 ## Public Testnet
-***Important!** As the amount of global Reticulum nodes and entrypoints have grown to a substantial quantity, the public Amsterdam Testnet entrypoint is slated for de-commisioning in the first quarter of 2026. If your own instances rely on this entrypoint for connectivity, it is high time to start configuring alternatives. Reticulum now includes a full on-network interface discovery and connectivity bootstrapping system. Read the [Bootstrapping Connectivity](https://reticulum.network/manual/gettingstartedfast.html#bootstrapping-connectivity) section of the manual for pointers.*
-
-If you just want to get started experimenting without building any physical
-networks, you are welcome to join the RNS Development Testnet.
-
-The testnet is just that, an informal network for testing and experimenting.
-It will be up most of the time, and anyone can join, but it also means that
-there's no guarantees for service availability.
-
-It probably goes without saying, but *don't use the testnet entry-points as 
-hardcoded or default interfaces in any applications you ship to users*. When
-shipping applications, the best practice is to provide your own default
-connectivity solutions, if needed and applicable, or in most cases, simply
-leave it up to the user which networks to connect to, and how.
-
-The testnet runs the very latest version of Reticulum (often even a short while
-before it is publicly released). Sometimes experimental versions of Reticulum
-might be deployed to nodes on the testnet, which means strange behaviour might
-occur. If none of that scares you, you can join the testnet via either TCP or
-I2P. Just add one of the following interfaces to your Reticulum configuration
-file:
-
-```
-# TCP/IP interface to the RNS Amsterdam Hub
-  [[RNS Testnet Amsterdam]]
-    type = TCPClientInterface
-    enabled = yes
-    target_host = amsterdam.connect.reticulum.network

+***Important!** Historically, a developer-targeted testnet was made available by the Reticulum project itself.

+>> Reticulum Network Stack
+
+To understand the foundational philosophy and goals of this system, read the [Zen of Reticulum](Zen%20of%20Reticulum.md).
+
+Reticulum is the cryptography-based networking stack for building local and wide-area networks with readily available hardware. It can operate even with very high latency and extremely low bandwidth. Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption and connectivity, initiator anonymity, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable delivery acknowledgements and more.
+
+The vision of Reticulum is to allow anyone to be their own network operator, and to make it cheap and easy to cover vast areas with a myriad of independent, inter-connectable and autonomous networks. Reticulum **is not** *one* network. It is **a tool** for building *thousands of networks*. Networks without kill-switches, surveillance, censorship and control. Networks that can freely interoperate, associate and disassociate with each other, and require no central oversight. Networks for human beings. *Networks for the people*.
+
+Reticulum is a complete networking stack, and does not rely on IP or higher layers, but it is possible to use IP as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks.
+
+Having no dependencies on traditional networking stacks frees up overhead that has been used to implement a networking stack built directly on cryptographic principles, allowing resilience and stable functionality, even in open and trustless networks.
+
+No kernel modules or drivers are required. Reticulum runs completely in userland, and can run on practically any system that runs Python 3.
+

+
+>> Reference Implementation
+
+The Python code in this repository is the Reference Implementation of Reticulum. The Reticulum Protocol is defined entirely and authoritatively by this reference implementation, and its associated manual. It is maintained by Mark Qvist, identified by the Reticulum Identity `B333<bc7291552be7a58f361522990465165c>`b.
+
+Compatibility with the Reticulum Protocol is defined as having full interoperability, and sufficient functional parity with this reference implementation. Any specific protocol implementation that achieves this is Reticulum. Any that does not is not Reticulum.
+
+The reference implementation is licensed under the Reticulum License.
+
+The Reticulum Protocol was dedicated to the Public Domain in 2016.
+
+>> Examples of Reticulum Applications
+
+If you want to quickly get an idea of what Reticulum can do, take a look at the [Programs Using Reticulum](https://reticulum.network/manual/software.html) section of the manual, or the following resources:
+
+• [LXMF](https://github.com/markqvist/lxmf) is a distributed, delay and disruption tolerant message transfer
+  protocol built on Reticulum
+
+• The [LXST](https://github.com/markqvist/lxst) protocol and framework provides real-time audio and signals
+  transport over Reticulum. It includes primitives and utilities for building voice-based applications and
+  hardware devices, such as the `B333rnphone`b program, that can be used to build hardware telephones.
+
+• For an off-grid, encrypted and resilient mesh communications platform, see [Nomad Network](https://github.com/markqvist/NomadNet)
+
+• The Android, Linux, macOS and Windows app [Sideband](https://github.com/markqvist/Sideband) has a graphical
+  interface and many advanced features, such as file transfers, image and voice messages, real-time voice calls,
+  a distributed telemetry system, mapping capabilities and full plugin extensibility.
+
+• [MeshChatX](https://git.quad4.io/RNS-Things/MeshChatX) is a full-featured LXMF client with many built-in tools
+  and functionalities, that also supports image and voice messages, file transfers and voice calls. It also
+  includes a built-in page browser for browsing Nomad Network nodes.
+
+• You can use the included [rnsh](https://reticulum.network/manual/using.html#the-rnsh-utility) program to
+  establish remote shell sessions over Reticulum.
+
+>> Where can Reticulum be used?
+
+Over practically any medium that can support at least a half-duplex channel with greater throughput than 5 bits per second, and an MTU of 500 bytes. Data radios, modems, LoRa radios, serial lines, AX.25 TNCs, amateur radio digital modes, WiFi and Ethernet devices, free-space optical links, and similar systems are all examples of the types of physical devices Reticulum can use.
+
+An open-source LoRa-based interface called [RNode](https://markqvist.github.io/Reticulum/manual/hardware.html#rnode) has been designed specifically for use with Reticulum. It is possible to build yourself, or it can be purchased as a complete transceiver that just needs a USB connection to the host.
+
+Reticulum can also be encapsulated over existing IP networks, so there's nothing stopping you from using it over wired Ethernet, your local WiFi network or the Internet, where it'll work just as well. In fact, one of the strengths of Reticulum is how easily it allows you to connect different mediums into a self-configuring, resilient and encrypted mesh, using any available mixture of available infrastructure.
+
+As an example, it's possible to set up a Raspberry Pi connected to both a LoRa radio, a packet radio TNC and a WiFi network. Once the interfaces are configured, Reticulum will take care of the rest, and any device on the WiFi network can communicate with nodes on the LoRa and packet radio sides of the network, and vice versa.
+
+>> How do I get started?
+
+The best way to get started with the Reticulum Network Stack depends on what you want to do. For full details and examples, have a look at the  [Getting Started Fast](https://markqvist.github.io/Reticulum/manual/gettingstartedfast.html)  section of the [Reticulum Manual](https://markqvist.github.io/Reticulum/manual/).
+
+To simply install Reticulum and related utilities on your system, the easiest way is via `B333pip`b. You can then start any program that uses Reticulum, or start Reticulum as a system service with [the rnsd utility](https://markqvist.github.io/Reticulum/manual/using.html#the-rnsd-utility).
+
+`B333
+`=
+pip install rns
+`=
+`b
+
+If you are using an operating system that blocks normal user package installation via `B333pip`b, you can return `B333pip`b to normal behaviour by editing the `B333~/.config/pip/pip.conf`b file, and adding the following directive in the `B333[global]`b section:
+
+`B333
+`=
+[global]
+break-system-packages = true
+`=
+`b
+
+Alternatively, you can use the `B333pipx`b tool to install Reticulum in an isolated environment:
+
+`B333
+`=
+pipx install rns
+`=
+`b
+
+When first started, Reticulum will create a default configuration file, providing basic connectivity to other Reticulum peers that might be locally reachable. The default config file contains a few examples, and references for creating a more complex configuration.
+
+If you have an old version of `B333pip`b on your system, you may need to upgrade it first with `B333pip install pip --upgrade`b. If you no not already have `B333pip`b installed, you can install it using the package manager of your system with `B333sudo apt install python3-pip`b or similar.
+
+For more detailed examples on how to expand communication over many mediums such as packet radio or LoRa, serial ports, or over fast IP links and the Internet using the UDP and TCP interfaces, take a look at the [Supported Interfaces](https://markqvist.github.io/Reticulum/manual/interfaces.html) section of the [Reticulum Manual](https://markqvist.github.io/Reticulum/manual/).
+
+>> Included Utilities
+Reticulum includes a range of useful utilities for managing your networks, viewing status and information, and other tasks. You can read more about these programs in the [Included Utility Programs](https://markqvist.github.io/Reticulum/manual/using.html#included-utility-programs) section of the [Reticulum Manual](https://markqvist.github.io/Reticulum/manual/).
+
+• The system daemon `B333rnsd`b for running Reticulum as an always-available service
+• An interface status utility called `B333rnstatus`b, that displays information about interfaces
+• The path lookup and management tool `B333rnpath`b letting you view and modify path tables
+• A diagnostics tool called `B333rnprobe`b for checking connectivity to destinations
+• A simple file transfer program called `B333rncp`b making it easy to transfer files between systems
+• The identity management and encryption utility `B333rnid`b let's you manage Identities and encrypt/decrypt files
+• The `B333rnsh`b program allows you to establish fully interactive shell session with remote systems
+• The remote command execution program `B333rnx`b let's you run simple commands and programs and retrieve output from remote systems
+• The `B333rngit`b program provides a full multi-repository Git node for serving repositories over Reticulum
+• The included `B333git-remote-rns`b helper allows you to interact with Git repositories over Reticulum
+
+All tools, including `B333rnx`b and `B333rncp`b, work reliably and well even over very low-bandwidth links like LoRa or Packet Radio. For full-featured remote shells over Reticulum, also have a look at the [rnsh](https://github.com/acehoss/rnsh) program.
+
+>> Supported interface types and devices
+
+Reticulum implements a range of generalised interface types that covers most of the communications hardware that Reticulum can run over. If your hardware is not supported, it's [simple to implement a custom interface module](https://markqvist.github.io/Reticulum/manual/interfaces.html#custom-interfaces).
+
+Currently, the following built-in interfaces are supported:
+
+• Any Ethernet device
+• LoRa using [RNode](https://unsigned.io/rnode/)
+• Packet Radio TNCs (with or without AX.25)
+• KISS-compatible hardware and software modems
+• Any device with a serial port
+• TCP over IP networks
+• UDP over IP networks
+• External programs via stdio or pipes
+• Custom hardware via stdio or pipes
+
+>> Performance
+Reticulum targets a *very* wide usable performance envelope, but prioritises functionality and performance on low-bandwidth mediums. The goal is to provide a dynamic performance envelope from 250 bits per second, to 1 gigabit per second on normal hardware.
+
+Currently, the usable performance envelope is approximately 150 bits per second to 500 megabits per second, with physical mediums faster than that not being saturated. Performance beyond the current level is intended for future upgrades, but not highly prioritised at this point in time.
+
+>> Current Status
+All core protocol features are implemented and functioning, but additions will probably occur as real-world use is explored and understood. The API and wire-format can be considered stable.
+
+>> Dependencies
+The installation of the default `B333rns`b package requires only two external dependencies, listed below. Almost all systems and distributions have readily available packages for these dependencies, and when the `B333rns`b package is installed with `B333pip`b, they will be downloaded and installed as well.
+
+• [PyCA/cryptography](https://github.com/pyca/cryptography)
+• [pyserial](https://github.com/pyserial/pyserial)
+
+On more unusual systems, and in some rare cases, it might not be possible to install or even compile one or more of the above modules. In such situations, you can use the `B333rnspure`b package instead, which require no external dependencies for installation. Please note that the contents of the `B333rns`b and `B333rnspure`b packages are *identical*. The only difference is that the `B333rnspure`b package lists no dependencies required for installation.
+
+No matter how Reticulum is installed and started, it will load external dependencies only if they are *needed* and *available*. If for example you want to use Reticulum on a system that cannot support [pyserial](https://github.com/pyserial/pyserial), it is perfectly possible to do so using the `B333rnspure`b package, but Reticulum will not be able to use serial-based interfaces. All other available modules will still be loaded when needed.
+
+**Please Note!** If you use the `B333rnspure`b package to run Reticulum on systems that do not support [PyCA/cryptography](https://github.com/pyca/cryptography), it is important that you read and understand the [Cryptographic Primitives](#cryptographic-primitives) section of this document.
+
+>> Bootstrapping Connectivity
+
+Reticulum is not a service you subscribe to, nor is it a single global network you "join". Reticulum provides functionality for discovering available public interfaces over the network itself, and the broader community has provided various directories of publicly available entrypoints to bootstrap connectivity.
+
+To learn how to establish initial connectivity over Reticulum, read the [Bootstrapping Connectivity](https://reticulum.network/manual/gettingstartedfast.html#bootstrapping-connectivity) section of the manual.
+
+If you already have a general idea of how this works, you can use community-run sites such as [directory.rns.recipes](https://directory.rns.recipes/) and [rmap.world](https://rmap.world) to find interface definitions for initial connectivity to the global distributed Reticulum backbone.
+
+>> Public Testnet
+***Important!** Historically, a developer-targeted testnet was made available by the Reticulum project itself. As the amount of global Reticulum nodes and entrypoints have grown to a substantial quantity, this public testnet, including the Amsterdam Testnet entrypoint, has now been decommissioned. If your still have instances that relied on this entrypoint for connectivity, transition to using the distributed backbone instead. Reticulum now includes a full on-network interface discovery and connectivity bootstrapping system. Read the [Bootstrapping Connectivity](https://reticulum.network/manual/gettingstartedfast.html#bootstrapping-connectivity) section of the manual for pointers.*

+
+>> Cryptographic Primitives
+Reticulum uses a simple suite of efficient, strong and well-tested cryptographic primitives, with widely available implementations that can be used both on general-purpose CPUs and on microcontrollers.
+
+One of the primary considerations for choosing this particular set of primitives is that they can be implemented *safely* with relatively few pitfalls, on practically all current computing platforms.
+
+The primitives listed here **are authoritative**. Anything claiming to be Reticulum, but not using these exact primitives **is not** Reticulum, and possibly an intentionally compromised or weakened clone. The utilised primitives are:
+
+• Reticulum Identity Keys are 512-bit Curve25519 keysets
+  • A 256-bit Ed25519 key for signatures
+  • A 256-bit X22519 key for ECDH key exchanges
+• HKDF for key derivation
+• Encrypted tokens are based on the [Fernet spec](https://github.com/fernet/spec/)
+  • Ephemeral keys derived from an ECDH key exchange on Curve25519
+  • HMAC using SHA256 for message authentication
+  • IVs must be generated through `B333os.urandom()`b or better
+  • AES-256 in CBC mode with PKCS7 padding
+  • No Fernet version and timestamp metadata fields
+• SHA-256
+• SHA-512
+
+In the default installation configuration, the `B333X25519`b, `B333Ed25519`b, and `B333AES-256-CBC`b primitives are provided by [OpenSSL](https://www.openssl.org/) (via the [PyCA/cryptography](https://github.com/pyca/cryptography) package). The hashing functions `B333SHA-256`b and `B333SHA-512`b are provided by the standard Python [hashlib](https://docs.python.org/3/library/hashlib.html). The `B333HKDF`b, `B333HMAC`b, `B333Token`b primitives, and the `B333PKCS7`b padding function are always provided by the following internal implementations:
+
+• [HKDF.py](RNS/Cryptography/HKDF.py)
+• [HMAC.py](RNS/Cryptography/HMAC.py)
+• [Token.py](RNS/Cryptography/Token.py)
+• [PKCS7.py](RNS/Cryptography/PKCS7.py)
+
+Reticulum also includes a complete implementation of all necessary primitives in pure Python. If OpenSSL and PyCA are not available on the system when Reticulum is started, Reticulum will instead use the internal pure-python primitives. A trivial consequence of this is performance, with the OpenSSL backend being *much* faster. The most important consequence however, is the potential loss of security by using primitives that has not seen the same amount of scrutiny, testing and review as those from OpenSSL.
+
+Please note that by default, installing Reticulum will **require** OpenSSL and PyCA to also be automatically installed if not already available. It is only possible to use the pure-python primitives if this requirement is specifically overridden by the user, for example by installing the `B333rnspure`b package instead of the normal `B333rns`b package, or by running directly from local source-code.
+
+If you want to use the internal pure-python primitives, it is **highly advisable** that you have a good understanding of the risks that this pose, and make an informed decision on whether those risks are acceptable to you.
+
+Reticulum is relatively young software, and should be considered as such. While it has been built with cryptography best-practices very foremost in mind, it _has not_ been externally security audited, and there could very well be privacy or security breaking bugs. If you want to help out, or help sponsor an audit, please do get in touch.

+# Zen of Reticulum
+
+## I: The Illusion Of The Center
+
+For the better part of a generation, we have been taught to visualize the digital world through the lens of hierarchy. The mental maps we carry are dominated by a single, misleading image: **The Cloud**.
+
+We imagine the network as a vast, ethereal space "up there" or "out there". A centralized repository of services and data to which we, the lowly clients, must connect. We build our software with this assumption hardcoded into our logic: *There is a server. The server has the authority. The server knows the way. I must find the server to function*.
+
+This is the Client-Server mental model, and it is the primary obstacle to understanding Reticulum.
+
+### Fallacy Of The Cloud
+
+The first step in the Zen of Reticulum is to realize that *there is no cloud*. There is only other people's computers. When you build for the cloud, you are building *for* a landlord. You are accepting that your application's existence is conditional on the permission, uptime, and continued goodwill of a central authority.
+
+In Reticulum, you must shift your thinking from "connecting to" to "being among". Reticulum is not a service you subscribe to - *it is a fabric you inhabit*. There is no "up there". There is only *here* and *there*, and the space between them is peer-to-peer.
+
+### Decentralization Or Uncentralizability?
+
+It is common to hear the word "decentralized" thrown around in modern tech circles. But often, this is merely a marketing term for "slightly distributed centralization". A blockchain with a few dominant miners, or a federated protocol with a few giant servers. *In practice*, it's still centralized. It simply has a few centers instead of one.
+
+Reticulum goes further. It wants **Uncentralizability**.
+
+This is not a wishful political stance, but a foundational mathematical characteristic of the protocol, onto which everything else has been built. Reticulum assumes that every peer on the network is potentially hostile, and every link is potentially compromised. It is designed with no "privileged" nodes. While some nodes may act as Transport Instances - forwarding traffic for others - they do so *blindly*, and they only know about their immediate surroundings, and nothing more. They route based on cryptographic proofs, not on administrative privilege. They cannot see who is talking to whom, nor can they selectively manipulate traffic without breaking their own ability to route entirely.
+
+The system is designed to make hierarchy structurally impossible. You cannot hijack an address, because there is no central registry to hijack. You cannot block a user, because there is no central switch to flip. You can offer paths through the network, but you can't force anyone to use them.
+
+### Death To The Address
+
+To break free of the center, you must also let go of the concept of the "Address".
+
+In the IP world, an address is a location. It is a coordinate in a *deeply hierarchical* and static grid. If you move your computer to a different house, your address changes. If your router reboots, your address might change. Your *identity* is bound to your *location*, and therefore, it is fragile, and easily controlled.
+
+Reticulum abolishes this link between *Identity* and *Location*.
+
+In Reticulum, an address is not a place; it is a **Hash of an Identity**. It is a cryptographic representation of *who* you are, not *where* you are. Because of this, your address is portable. You can take a laptop from a WiFi cafe in Berlin, to a LoRa mesh in the mountains, to a packet radio link on a boat, and your "address" - your *Destination Hash* - never changes.
+
+The network does not route to a place; it routes to a *person* (or a machine). When you send a packet, you are not targeting a coordinate in a grid; you are encrypting a message for a specific entity. The network dynamically discovers where that entity currently resides, and it does so in a way where no one really knows where that entity is actually located physically.
+
+**Consider:**
+
+- **The Old Way:** *"I am at `192.168.1.5`. Come find me"*.
+- **The Zen Way:** *"I am `<327c1b2f87c9353e01769b01090b18f2>`. Wherever I am, my peers can reach me"*.
+
+Once you stop thinking about servers and start thinking about portable identities, where everyone can always reach everyone else directly, the illusion of the center fades away. You realize there *is* no center holding the network together. No coordinators or bureaucrats required. The network is simply the sum of its peers, communicating directly, sovereignly, and without a master.
+
+
+## II: Physics Of Trust
+*Paranoia Is A Great Design Principle*
+
+If we accept that there is no center - that the network is a chaotic, peer-to-peer mesh - we are forced to confront a terrifying reality: **There is no one guarding the door**.
+
+In the traditional networking mindset, we rely on the concept of the "trusted core". We assume our local coffee shop WiFi is safe, or that the backbone providers are neutral custodians. We build our security like a castle: strong walls on the outside, soft and trusting on the inside. We use encryption only when we step out into the "wild" internet.
+
+### Hostile Environments
+
+The Zen of Reticulum requires you to invert this. You must assume that *every* environment is hostile. This isn't cynicism, just uncaring physics.
+
+When you transmit information over radio waves, you are shouting into a crowded room. Anyone can listen. When you traverse the internet, your packets pass through routers controlled by strangers, corporations, and state actors. Assuming privacy in this environment without cryptographic protection is not optimism but gross negligence.
+
+Reticulum is built on the premise that every link is tapped, and every peer is a potential adversary. If your system cannot survive an adversary owning the physical layer, it cannot survive at all.
+
+But this is the paradox: By assuming the network is hostile, you make it safe. When you accept the dangers for what they are, they become manageable. When you stop trusting the infrastructure and start trusting the math, you eliminate the single point of failure: Human integrity.
+
+### Encryption Is Not A Feature
+
+In the world of TCP/IP, encryption is an afterthought. It is a layer we slap on top of the protocol (HTTPS, TLS) to patch the security holes of the original design. It is a "feature" you sometimes *enable* for "sensitive data". This is fundamentally flawed, since all data is sensitive.
+
+In Reticulum, encryption is **gravity**.
+
+It is not optional. It is not a plugin. It is the *fundamental force that allows the network to exist*. If you were to strip the encryption from Reticulum, the routing would break. The Transport system uses cryptographic signatures and entropy to verify paths and pass information. If packets were plaintext, intermediate nodes could not prove that a route was valid, nor could endpoints prevent spoofing or tampering.
+
+In Reticulum, the entropy of the encrypted packet *is* the routing logic.
+
+To ask for a version of Reticulum without encryption is like asking for a version of the ocean without liquid. You are not asking for a feature change; you're asking for a different physical universe. We design for a universe where information has mass, structure, and integrity.
+
+### Zero-Trust Architectures
+
+We must unlearn our reliance on **Institutional Trust**.
+
+For decades, we have been trained to trust authorities. We trust a website because a chain of Certificate Authorities (companies we don't know) vouches for it. We trust an app because it is in an app store (run by a corporation we don't control). We trust a message because it comes from a phone number assigned by a telecom. Yet, everything in our digital information sphere today is more untrustworthy and risky than a medieval second-hand underwear market.
+
+Reticulum replaces institutional trust with **Cryptographic Proof**.
+
+In Reticulum, you do not trust a node because it has a nice hostname or because it is listed in a directory. You trust it because it holds the private key corresponding to the Destination Hash you are communicating with. This trust is binary, mathematical, and **absolute**. Either the signature matches, or it does not. There is no "maybe".
+
+This shift moves the power from the institution to the individual. You become the ultimate arbiter of your own trust relationships. You decide which keys to accept, which paths to follow, and which identities to recognize.
+
+**Consider:**
+
+- **The Old Way:** *"I trust this site because the browser says the lock icon is green"*.
+- **The Zen Way:** *"I trust this destination because I have verified its hash fingerprint out-of-band, and the math confirms the signature"*.
+
+When you internalize the Physics of Trust, you stop looking for protection from firewalls, VPNs, and Terms of Service agreements. You realize that true security comes from the design of the protocol itself. You can stop trusting the cloud, and you start trusting the code - because you can verify it yourself.
+
+
+## III: Merits Of Scarcity
+*Every Bit Counts*
+
+We have grown addicted to abundance. In the modern digital ecosystem, bandwidth is treated as an endless, flat ocean. We stream high-definition video without a thought, we ship entire libraries of code just to render a single button, and we measure performance in gigabits per second. This abundance has hollowed out our craft. When constraints vanish, efficiency dies, and with it, a certain kind of Clarity and Quality.
+
+Reticulum asks you to step out of the ocean and onto the tightrope.
+
+### The Bandwidth Fallacy
+
+The Zen of Reticulum requires the realization that **5 bits per second is a valid speed**.
+
+To a modern developer, this sounds like paralysis. But there is a profound freedom in limits: When you have a gigabit connection, you can be incredibly sloppy. You can be wasteful. You can push your problems onto the infrastructure. *"It’s slow? Get a faster router"*.
+
+But on a high-latency, low-bandwidth link (be it a noisy HF radio channel or a tenuous LoRa hop) you cannot push problems anywhere. You must solve them. The network does not negotiate with waste.
+
+This forces a shift from consumption to interaction. You are no longer, then, consuming a service provided by a fat pipe; you are engaging in a careful negotiation with the physical medium. The medium becomes a partner in the conversation, not just a dumb conduit. You suddenly need to *understand the world to be in it*.
+
+### Cost Of A Byte
+
+In a scarce economy, a byte is not just data, but energy, time, and space.
+
+Every byte you transmit consumes battery life on a solar-powered node. It occupies valuable airtime that could have been used by another peer. It represents a measurable slice of the electromagnetic spectrum.
+
+When you internalize this, you begin to write code differently. You stop asking, "How much data can I send?" and start asking, "What is the *minimum* amount of information required to convey this intent? How can I best utilize my informational entropy?"
+
+This is where the elegance of Reticulum shines. The protocol is designed to strip away the non-essential. A link establishment takes three very small packets. A destination hash fits in 16 bytes. The overhead is vanishingly small, leaving almost the entire channel for the message itself.
+
+**Consider:**
+
+- **The Old Way:** *"I need to send a status update. I'll send a JSON object with metadata, timestamps, and user profile info (15KB)."*
+- **The Zen Way:** *"I need to send a status update. I'll send a single byte representing the state code. The context is already known."*
+
+This is of course optimization, but more importantly, *it is a form of respect*. Efficiency in a shared medium is an act of stewardship. By taking only what you need from the network, you leave room for others. The network listens to those who speak with purpose.
+
+### Flow & Time
+
+Scarcity also teaches us about time. We have become addicted to the *synchronous* now - the instant ping, the real-time stream. But Reticulum embraces *asynchronous* time.
+
+When links are intermittent and latency is measured in minutes or hours, "real-time" is an illusion. Reticulum doesn't encourage **Store and Forward** as a mere fallback, but as a primary mode of existence. You write a message, it propagates when it can, and it arrives when it arrives.
+
+This changes the psychological texture of communication. It removes the anxiety of the immediate response. It allows for contemplation. You are not demanding the recipient's attention *right now*; you are placing a gift in their path, to be found when they are ready.
+
+By designing for delay, you design for resilience. You are no longer building a house of cards that collapses when a single packet drops. You are building a stone arch that distributes the load *over time*.
+
+### Liberation From Limits
+
+There is a strange optimism in scarcity. When you are forced to work within strict constraints, you are forced to prioritize. *You* must decide what truly matters. *That* is the real core of agency.
+
+In the infinite fantasy world of The Cloud, everything is urgent, so nothing is. In the economy of Reticulum, the cost of transmission forces you to weigh the value of your message. Do you really need to send that heart beat? Is that photo essential?
+
+When you strip away the noise, what remains is *signal*.
+
+This discipline creates a different kind of developer. It creates a craftsman who understands that the best code is the code you don't have to write. It creates a user who understands that the most powerful message is the one that is *understood*, not the one that is loudest. In the world of Reticulum, you are not a mere consumer of bandwidth; you are an architect of intent.
+
+
+## IV: Sovereignty Through Infrastructure
+**Be Your Own Network**
+
+We live in an era of digital tenancy. We lease our connectivity from ISPs. We rent our storage from cloud providers. We even borrow our identity from social media platforms. We are tenants in a house we did not build, governed by rules we did not write, subject to eviction at the whim of a landlord who has never met us.
+
+The Zen of Reticulum is the realization that you *can* own the house.
+
+### A Carrier-Grade Fallacy
+
+For decades, we have been gaslit into believing that networking is really not just hard, but impossible. It is presented as a dark art reserved for telcos and billionaires, requiring millions of dollars of fiber optics, climate-controlled data centers, and armies of engineers. We are told that building reliable infrastructure is "too complex" for the individual or small organization.
+
+This is a big, fat lie.
+
+Physics is simple. A radio wave needs a transmitter and a receiver. A packet needs a path. The "complexity" of the modern internet is largely bureaucratic - a mountain of billing systems, regulatory capture, and legacy cruft designed to keep the gatekeepers in power.
+
+Reticulum strips away the bureaucracy. It runs on hardware that costs the price of a dinner. It runs on spectrum that is free to use. It demonstrates that a robust, planetary-scale network does not require a Fortune 500 company. It requires only the will to deploy, and the distributed, uncoordinated efforts of many individuals.
+
+### Personal Infrastructure
+
+This is where the rubber meets the road. You can read about Reticulum, you can understand the theory, but the insights only arrive when you plug in a radio and run a Transport Node. Suddenly, you are no longer a consumer. You're an operator.
+
+This shift is subtle but profound. When you run your own infrastructure, the network ceases to be a service that is provided *to* you. It becomes a space that you *inhabit*. You become responsible for the flow of information. You gain an intimate understanding of the medium - the way the weather affects the radio waves, the way the topology changes, the way the packets dance through the ether.
+
+There is a quiet competence that comes from this. You stop asking "Is the internet down?" and start asking "Is *my* links up?" You stop waiting for a technician and start checking the logs. This is a form of strength. To understand the system that carries your words is to be free from the mystery that keeps you dependent.
+
+### The Ability To Disconnect
+
+Why go to the trouble? Why buy the radio, write the config, and leave the Pi running in the corner?
+
+Because the old, centralized network is fragile. And because most of us doesn't even really want to be there anymore.
+
+The internet we rely on today is a chain of single points of failure. Cut the undersea cable, and a continent goes dark. Shut down the power grid, and the cloud evaporates. Deprioritize the "wrong" traffic, and the flow of information is strangled.
+
+Sovereignty is the ability to survive the cut, whether or not that cut was an accident or on purpose.
+
+When you build your own infrastructure, you build a lifeline. Reticulum is designed to function over media that the traditional internet cannot touch - bare wires, battery-powered radios, ad-hoc WiFi meshes. When the grid fails, or the censors arrive, or the bill goes unpaid, your Reticulum network continues to hum.
+
+This is not about "dropping out" of society. It is about building a substrate on which an actual *Society* can function.
+
+**Consider:**
+
+- **The Old Way:** "My connection is slow. I should call my ISP and complain."
+- **The Zen Way:** "The path is noisy. I will adjust the antenna or find a better route."
+
+By taking ownership of the infrastructure, you take ownership of your voice. You stop shouting into someone else's megaphone and start building your own. The network is no longer something that happens to you; it is something you make happen.
+
+
+# V: Identity and Nomadism
+**A Fluid Self**
+
+In the old world, you are defined by your coordinates. If you are at `34.109.71.5`, you're *here*. If you unplug the cable and walk down the street, you vanish. Your digital self evaporates because it was tethered to the wall. You are a ghost in the endless machinations of gears, levers and transistors, bound to the hardware, and those that own it.
+
+This creates a subtle, constant anxiety. We are terrified of disconnecting because, in the architecture of the old web, disconnecting is a kind of death.
+
+The Zen of Reticulum offers a different way to be.
+
+### Portable Existence
+
+In Reticulum, your identity is not a location, or a username granted by a service. It is a cryptographic key - a complex, unique mathematical signature that exists independently of the physical world. You can carry it only in your mind, if you want to.
+
+Think of it less like a street address and more like a name. *A true name*.
+
+If you travel from Berlin to Tokyo, you do not change your name. You are still you. The people who know you can still recognize you. Reticulum applies this principle to the network layer. Your Destination Hash is **invariant**. It travels with you, stored securely on your device, *immutable as a stone*.
+
+This changes the relationship between you and the machine. You are not "logged into" the network via a specific gateway. You *are* the endpoint. The network does not connect to a place; *it converges on you*.
+
+### Roaming Nodes
+
+This freedom introduces a new concept of time and space: **Nomadism**.
+
+Because your identity is portable, your connectivity can be fluid. You can be sitting at a desk connected to a fiber backbone one moment, and walking through a field connected only to a long-range LoRa mesh the next. To the rest of the network, nothing has changed. Your friends do not need to update your contact info. The messages they send do not bounce back. The network senses the shift in the medium and reroutes the flow of data automatically.
+
+You are no longer a stationary node in a fixed grid. You are a wanderer in a fluid medium.
+
+The interfaces - whether it is WiFi, Ethernet, Packet Radio, or a physical wire - is merely the clothing your node wears. You change it to suit the environment. Underneath, you remain the same. This is the liberation of the protocol. It treats the physical medium as a transient circumstance, not a definition of self.
+
+**Consider:**
+
+- **The Old Way:** *"I lost connection. I have to reconnect to the VPN to tell them where I am now."*
+- **The Zen Way:** *"I moved. The network subtly bends to accomodate this new reality."*
+
+### Announcing Presence
+
+How does the network find a wanderer? It listens.
+
+In the IP world, we query directories. We ask a server, "Where is Mark?" The server checks its database and gives us a coordinate. This means that someone, somewhere, is keeping track of you. It assumes and *requires* surveillance.
+
+Reticulum replaces surveillance with **Announces**.
+
+Instead of asking a central authority where you are, you simply state your presence. You broadcast a cryptographic proof: "I am here, and I am who I say I am". This ripples out through the mesh. Your neighbors hear it, update their path tables, and pass it on.
+
+This is a quiet, organic process. It is the digital equivalent of lighting lanterns in the dark. You do not need to chase the light; you let the light find you. It respects your autonomy. You choose when to announce, how often to speak, and to whom. You also choose when to disappear - for but a moment or perpetually.
+
+### Anchor In The Flow
+
+There is a deep peace in this nomadism. It teaches you that stability does not come from standing still. Stability comes from *internal coherence*.
+
+By holding your own private key, you hold your own center of gravity. The world around you; the infrastructure, the topography and the availability of links can all shift chaotically. Storms can knock out towers. Cables can be cut. The internet can go down.
+
+But as long as you possess your key, you possess your identity. The entire infrastructure can be destroyed and rebuilt, and you are still you. Nothing lasts, yet nothing is lost.
+
+You become a sovereign entity moving through the noise, connected not by the rigidity of cables, but by the fluidity of recognition. The network becomes a place you inhabit, rather than a utility you subscribe to: You are at home in the ether.
+
+
+## VI: Ethics Of The Tool
+**Technology With Conscience**
+
+You have unlearned the center. You have accepted the physics of trust. You have embraced the economy of scarcity and the freedom of unbound nomadism. You are standing in a new space. Now, look at the tool in your hand.
+
+In the old world, we were taught that technology is neutral. We are told that "guns don't kill people, people do", or that a component is just a component, indifferent to what its combinatorial potential is. This is a convenient lie. It serves only to allow the builders to wash their hands of responsibility.
+
+But we know better now. We know that **architecture is politics**, and *politics is control*. The way you build a system determines how it will be used. If you build a system optimized for mass surveillance, you *will* get a panopticon. If you build a system optimized for centralized control, you *will* get a dictatorship. If you build a system optimized for extraction, you *will* get a parasite.
+
+The Zen of Reticulum asserts that a tool is never neutral.
+
+On the very contrary: A tool is intent, **crystallized**.
+
+### The Harm Principle
+
+Why does the Reticulum License forbid the software from being used in systems designed to harm humans? Is it not just a restriction on freedom?
+
+It is a restriction on *license*, yes, but it is an expansion of *freedom*.
+
+Building powerful tools without a moral compass is in no way virtuous or commendable, it is plain and simple irresponsibility.
+
+A tool that can easily be used to oppress is a real danger to the user. If you build a network that can be turned against you by a tyrant, you are not free. You are merely waiting for the leash to tighten. By encoding the "Harm Principle" into the legal DNA of the reference implementation, we are building a safeguard. We are stating, clearly and immutably, that *this tool* is for **life**, not for death.
+
+This aligns the software with the interests of humanity. It cements that the network cannot be conscripted into a kill-system, a weaponized drone controller, or a torture device without breaking the license and the law. It is a line drawn in the sand - not by a government or external authority, but by the creators of the tool itself.
+
+**Consider:**
+
+- **The Old Way:** *"It's just software. How people use it is not my problem."*
+- **The Zen Way:** *"This software is a habitat. I will not allow it to be used to build a cage."*
+
+It is *your* choice whether to align with this - we are not forcing this stance on anyone. If you choose to align with life over death, with creativity over destruction, we grant you an immensely powerful tool, to own and build with as you please. If you do not, we deny it.
+
+If you do not like this, we most assuredly do not need you here, and you are on your own.
+
+### Public Domain Protocol
+
+This leads to a vital distinction: The difference between the *idea* and the *implementation*.
+
+The protocol - the mathematical rules of how Reticulum works - is dedicated to the Public Domain. It belongs to humanity. **No one can own it**. Anyone can implement it, improve it, or adapt it. This is the core idea of free communication, which itself must be forever free.
+
+But the functional, deployed *reference implementation* - the Python code, the maintenance, the years of labor - has a conscience. This distinction is the engine of sustainability. It allows the protocol to be universal, while ensuring that the specific labor of the builders is not hijacked to undermine the foundational intent of the project itself. From this document, it should be very clear what this intent is.
+
+If you want to build a system with Reticulum that manipulates and damages users for profits or targets missiles, you can use the public domain protocol, and start from scratch. But you cannot take our work. You must do your own. This serves as a pillar of accountability. If you want to build a weapon, *you* go and forge the steel yourself, while the world observes. And when the blood is drawn - it is on **your** hands.
+
+### Preserving Human Agency
+
+We live in an era of predatory extraction. The open-source commons is being scraped, ingested, and regurgitated by machine learning algorithms, whose corporate owners seek to replace the very humans who built those commons. Our code, our words, and our creativity is being used to train systems that are specifically designed to make us obsolete, without offering anything else in return than serfdom and leashes.
+
+Reticulum stands against this.
+
+The license protects the software from being used to feed the beast. It draws a hard line: This tool is for *people*. It is for human-to-human connection. It is not a dataset to be strip-mined for the purpose of building a synthetic overlord, puppeteered by a miniscule conglomerate of controllers.
+
+This is a radical act of preservation. By protecting the code from AI appropriation, we are protecting space for human agency. We are ensuring that there remains a digital realm where the actors are flesh, blood and soul, where decisions are made by minds, not overlords hiding behind models.
+
+When you use Reticulum, you are using a tool that respects you. It does not see you as a product to be tracked. It does not see your data as fuel for an algorithm. It sees you as a sovereign, equal peer.
+
+This changes the foundational premise of using the technology. It restores dignity to the interaction. You are not the user of a service; you are a participant in a mutual covenant. The tool aligns with your autonomy, rather than eroding it.
+
+In this way, ethics is not a restriction, but a foundation. It is the foundation that helps ensure the network will still belong to you tomorrow.
+
+
+## VII: Design Patterns For Post-IP Systems
+**Practical Philosophy for Developers**
+
+The philosophy is useless if it cannot be hammered into code. The metaphors we have explored - nomadism, scarcity, trust - are not just poetry, but real-world engineering constraints. When you sit down to write software for Reticulum, these concepts must shape the very structure of your application.
+
+We are now moving from the *why* to the *how*. This is where the abstract becomes concrete, and where you will see the true depth of the patterns we have been weaving.
+
+### Store & Forward
+
+The web has trained us to be impatient. We write synchronous code. We fire a request and we wait, blocking the UI, holding our breath. If the response doesn't come in 250 milliseconds, we show a spinner. If it doesn't come in five seconds, we show an error. We treat network connectivity as a binary state: either we are "online" or we are "broken".
+
+This is brittle. It is a rejection of reality.
+
+In Reticulum, connectivity is a spectrum, and presence is asynchronous. If at all applicable to your intent, you must design your applications to embrace **Store & Forward**.
+
+Instead of demanding an immediate answer, your application should act as a patient participant. You create a message for someone or something in the mesh. The network holds it. It carries it from node to node, perhaps over hours or days, waiting for the recipient to appear. When they finally surface, the message is delivered. This requires a shift from "request/response" to "event/handler". How exactly you do this is a challenge for you to solve intelligently within your problem domain, but Reticulum-based systems already exist that does this extremely well, and you can use them for inspiration.
+
+**Consider:**
+
+- **The Old Way:** `Connect() -> Send() -> Wait() -> Crash if timeout.`
+- **The Zen Way:** `Send() -> Continue living. -> Receive() when it arrives.`
+
+This changes the user experience profoundly. It removes the anxiety of the loading bar. It creates a sense of continuity. The user is not "waiting for the network"; they are interacting with a persistent log of communication that lives in the network itself.
+
+### Naming Is Power
+
+In the IP world, we are slaves to the Domain Name System. We rely on a hierarchy of registrars to map human-readable names to machine-readable addresses. This hierarchy is a choke point. If the registrar revokes your domain, or if the DNS server goes down, you vanish.
+
+Reticulum dissolves this hierarchy with **Hash-based Identity**.
+
+In this design pattern, a name is not a string you look up; it is a cryptographic destination you verify. When you design for Reticulum, you stop asking the user for a URL and start asking for a Destination or Identity Hash.
+
+This feels strange at first. A hash like `<83b7328926fed0d2e6a10a7671f9e237>` looks alien compared to `myfriend.com`. But that alienness is the armor. It **cannot** be spoofed. It **cannot** be censored by a registrar. It is **absolute**.
+
+Designing for this means shifting your UI metaphors. You are no longer browsing a web of pages; you are managing a ledger of keys. You are building an "Address Book" that is actually a keyring. The names are given by the user, and the power stays with them. That hashes look complex is directly analogous to the strengths of the bonds formed by their use. It forces the user to engage in a moment of verification, an out-of-band handshake, which restores the human element of trust that SSL certificates stripped away.
+
+### The Interface Is The Medium
+
+One of the most liberating patterns in Reticulum is **Transport Agnosticism**.
+
+In traditional networking, your code is often littered with transport logic. "Am I on WiFi? Check bandwidth. Am I on Cellular? Check data plan. Am I on Ethernet?". You are constantly micromanaging the pipe.
+
+In Reticulum, you write to the API, and the API writes to the medium. You send a packet to a Destination. You do not care if that packet travels over a TCP tunnel, a LoRa radio wave, or a serial wire interface. That is the stack's concern.
+
+This allows you to write **Universal Applications**.
+Imagine a messaging app. You write it once. It works on a laptop connected to fiber. It works on a phone in the city using WiFi. And, without a single line of code changed, it works on a device in the wilderness, talking only to other devices via radio.
+
+The pattern is simple: **Never code to the hardware. Code to the intent.**
+
+**Consider:**
+
+- **The Old Way:** `socket.connect(ip, port)`
+- **The Zen Way:** `RNS.Packet(destination, data).send()`
+
+By abstracting the medium, you make your software immortal to changes in infrastructure. The user might switch from a 4G hotspot to a HF modem tomorrow. Your software doesn't need to know. It simply continues the conversation.
+
+### Emergent Patterns
+
+When you combine these patterns - *Store & Forward*, *Hash-based Identity*, and *Transport Agnosticism* - you create software that feels fundamentally different.
+
+It feels *grounded*. It doesn't flicker when the signal drops. It doesn't panic when the server is down. It has weight. It has persistence. It has *relevance*.
+
+You are no longer building a "client" that begs a "server" for attention. You are building an autonomous agent that exists within the mesh. It speaks when it needs to, listens when it can, and carries its identity with it wherever it goes.
+
+This is the culmination of the Zen. The code is not just a set of instructions: It is a behavioral envelope. It is a way of *being* in the network.
+
+
+## VIII: Fabric Of The Independent
+
+We have stripped away the illusions. We have seen that the center is empty, that trust *must* be hard, that resources are finite, and that we must own our infrastructure. We have seen that tools have ethics and that our identity can move fluidly.
+
+This is a reclaiming of the commons. For too long, we have allowed the most vital substrate of human society - *our ability to speak to one another* - to be colonized by entities that do not share our interests. We have allowed the architecture of our communication to be designed by accountants rather than architects.
+
+We are taking it back. Not by petitioning the masters, but by building the new world within, over, under and around the shell of the old.
+
+### The Work Is Finished
+
+The heavy lifting is done.
+
+The protocol is in the public domain, a gift to humanity that can never be taken away. The software is written, tested, and running on devices scattered across the globe. The manual lies open before you. The source code for the reference implementation is now distributed on hundreds of thousands of devices across the planet. No one can delete or destroy it. The hardware is accessible and abundant.
+
+It was a hard road to get here, but we got here. Now, there is no roadmap committee waiting for approval. There is no venture capital dictating the user experience. There is no CEO to sign off on the next feature release.
+
+There is only you.
+
+The barrier to entry is no longer complexity: It is the mere habit of dependency. You were conditioned to wait. Wait for the app update. Wait for the ISP to fix the line. Wait for the platform to allow the post. Wait for the government to change the policies. Wait for the likes. Wait for the revolution to be televised.
+
+The revolution never was televised.
+
+It is packetized.
+
+### Open Sky
+
+The future of this technology is a construction project.
+
+It looks like a single node on a windowsill, listening to the static. It looks like a message sent to a neighbor, bypassing the noise of the commercial web. It looks like a community mesh that grows, link by link, hop by hop, carried by hands that care more about connection than profit.
+
+You have the blueprints. You have the tools. You have the philosophy. The noise of the old world has fallen away, leaving you with the quiet clarity of the open spectrum.
+
+*Mark, early 2026*

+************************
+Using Git Over Reticulum
+************************
+
+A set of utilities for distributed collaborative software development and publishing is included in RNS.
+
+The system consists of two parts: The ``rngit`` node that hosts repositories, and the ``git-remote-rns`` helper that enables Git to communicate with rngit nodes. As soon as you have RNS installed on your system, you can transparently use Git with Reticulum-hosted repositories just like any other type of remote. Git over Reticulum uses URLs in the following format: ``rns://DESTINATION_HASH/group/repo``.
+
+If you set a branch to track a Reticulum remote as the default upstream, you can simply use ``git`` as you normally would; all commands work transparently and as expected.
+
+.. warning::
+   **The rngit program is a new addition to RNS!** This functionality was introduced in RNS 1.2.0. While great care has been taken to design a secure, but highly configurable and flexible permission system for allowing many users to interact with many different repositories on a single node, ``rngit`` has not been tested extensively in the wild! Be careful when hosting repositories, especially if they are public or semi-public.
+
+The rngit Utility
+=================
+
+The ``rngit`` utility provides full Git repository hosting and interaction over Reticulum. It allows you to host and manage Git repositories and releases on Reticulum nodes, and to interact with remote repositories using standard Git commands through the ``rns://`` URL scheme.
+
+**Usage Examples**
+
+Run ``rngit`` to start a repository node:
+
+.. code:: text
+
+  $ rngit
+
+  [Notice] Starting Reticulum Git Node...
+  [Notice] Reticulum Git Node listening on <0d7334d411d00120cbad24edf355fdd2>
+
+On the first run, ``rngit`` will create a default configuration file. You will then need to edit this, to point to your repository locations, configure access permissions, and perform any other necessary configuration.
+
+View your identity and destination hashes:
+
+.. code:: text
+
+  $ rngit --print-identity
+
+  Git Peer Identity         : <959e10e5efc1bd9d97a4083babe51dea>
+  Repository Node Identity  : <153cb870b4665b8c1c348896292b0bad>
+  Repositories Destination  : <0d7334d411d00120cbad24edf355fdd2>
+
+If the page server is enabled, the output will also include the Nomad Network destination hash.
+
+You can run ``rngit`` in service mode with logging to file:
+
+.. code:: text
+
+  $ rngit -s
+
+Clone a repository from a remote ``rngit`` node:
+
+.. code:: text
+
+  $ git clone rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo
+
+Add a Reticulum remote to an existing repository:
+
+.. code:: text
+
+  $ git remote add some_remote rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo
+
+Push changes to the Reticulum remote:
+
+.. code:: text
+
+  $ git push some_remote master
+
+Get changes from a remote repository:
+
+.. code:: text
+
+  $ git pull rns_remote master
+
+**All Command-Line Options (rngit)**
+
+.. code:: text
+
+  usage: rngit.py [-h] [--config CONFIG] [--rnsconfig RNSCONFIG] [-s] [-i] [-v]
+                  [-q] [--version]
+
+  Reticulum Git Repository Node
+
+  options:
+    -h, --help            show this help message and exit
+    --config CONFIG       path to alternative config directory
+    --rnsconfig RNSCONFIG
+                          path to alternative Reticulum config directory
+    -p, --print-identity  print identity and destination info and exit
+    -s, --service         rngit is running as a service and should log to file
+    -i, --interactive     drop into interactive shell after initialisation
+    -v, --verbose         increase verbosity
+    -q, --quiet           decrease verbosity
+    --version             show program's version number and exit
+
+**All Command-Line Options (git-remote-rns)**
+
+The ``git-remote-rns`` helper is automatically invoked by Git when interacting with ``rns://`` URLs. It is not typically run directly by users, but accepts the following environment variables for configuration:
+
+- ``RNGIT_CONFIG`` - Path to alternative client configuration directory
+- ``RNS_CONFIG`` - Path to alternative Reticulum configuration directory
+
+The client configuration file is located at ``~/.rngit/client_config`` and allows adjusting parameters such as the reference batch size for transfers.
+
+
+Repository Structure
+====================
+
+The ``rngit`` node organizes repositories into groups. Each group is a directory containing bare Git repositories. The repository path format is ``group_name/repo_name``. For example, a repository at ``/var/git/public/myrepo`` would be accessible as ``public/myrepo`` via the URL ``rns://DESTINATION_HASH/public/myrepo``.
+
+**Configuration**
+
+The ``rngit`` node configuration file is located at ``~/.rngit/config`` (or ``/etc/rngit/config`` for system-wide installations). The default configuration includes:
+
+- Repository group paths defining where to find bare repositories
+- Access permissions for groups and individual repositories
+- Announce intervals for network visibility
+- Optional statistics recording for repository activity
+
+Access permissions can be configured at the group level in the config file, or per-repository using ``.allowed`` files. Permissions use the format ``permission:target`` where permission is ``r`` (read), ``w`` (write), ``rw`` (read/write), ``c`` (create) or ``s`` (stats) and target is ``all``, ``none``, or a specific identity hash.
+
+The ``s`` (stats) permission allows viewing repository activity statistics, including views, fetches and pushes over time. To enable statistics recording, set ``record_stats = yes`` in the ``[rngit]`` section of the configuration file. You can also exclude specific identities from statistics by adding their hashes to ``stats_ignore_identities``.
+
+Repository-specific ``.allowed`` files can be static text files or executable scripts that output permission rules to stdout. A ``group.allowed`` file in a repository group directory applies to all repositories within that group.
+
+Serving Pages Over Nomad Network
+================================
+
+In addition to providing Git repository access via the Git remote helper protocol, ``rngit`` can also run a `Nomad Network <https://github.com/markqvist/nomadnet>`_ compatible page node. This allows users to browse repository information, view file contents, inspect commit history and access repository statistics through any Nomad Network client.
+
+When enabled, the page node provides a complete interface to your repositories, with automatic Markdown to Micron conversion, syntax-highlighted code browsing, and detailed commit, diff and statistics views.
+
+**Enabling the Git Page Node**
+
+To enable the page node, add the following to your ``~/.rngit/config`` file:
+
+.. code:: text
+
+  [pages]
+  serve_nomadnet = yes
+
+When the page node is enabled, ``rngit`` will listen on a Nomad Network node destination in addition to the Git repository destination. You can view the destination hash by running:
+
+.. code:: text
+
+  $ rngit --print-identity
+
+  Git Peer Identity         : <959e10e5efc1bd9d97a4083babe51dea>
+  Repository Node Identity  : <153cb870b4665b8c1c348896292b0bad>
+  Repositories Destination  : <0d7334d411d00120cbad24edf355fdd2>
+  Nomad Network Destination : <50824b711717f97c2fb1166ceddd5ea9>
+
+**Accessing Repository Pages**
+
+Once the page server is running, you can access it from any Nomad Network client by connecting to the Nomad Network destination. The page node provides the following views:
+
+- **Front Page** - Lists all repository groups accessible to your identity
+- **Group Page** - Shows all repositories within a group
+- **Repository Page** - Displays repository overview, description and README
+- **Releases** - List of releases for the repository, with information and downloads
+- **File Browser** - Browse directory trees and view and download file contents
+- **Commits View** - View commit history with pagination
+- **Commit Details** - Detailed commit information with file changes and diffs
+- **Refs View** - List branches and tags
+- **Statistics** - Activity charts showing views, fetches and pushes over time
+
+All pages respect the same permission system used for Git access. If an identity does not have read access to a repository, they will not be able to view its pages.
+
+Formatting & Syntax Highlighting
+================================
+
+If the ``pygments`` Python module is installed on your system, the page server will automatically apply syntax highlighting to code files. The highlighting supports a wide range of programming languages and uses a color theme optimized for terminal display.
+
+To enable syntax highlighting, install pygments:
+
+.. code:: text
+
+  pip install pygments
+
+**Markdown & Micron Support**
+
+README files and other Markdown documents are automatically converted to Micron markup for display in Nomad Network clients. You can also write your README files directly in Micron, in which case they will display and render as such in any Nomad Network client. The file browser also supports viewing both rendered and raw Markdown and Micron documents.
+
+Code blocks in Markdown can include language hints for syntax highlighting:
+
+.. code:: text
+
+  ```python
+  def hello_world():
+      print("Hello, Reticulum!")
+  ```
+
+Customizing Templates
+=====================
+
+The page server uses a template system that allows complete customization of the generated pages. Templates are stored in the ``~/.rngit/templates/`` directory as Micron files.
+
+The following template files are supported:
+
+- ``base.mu`` - Base template wrapping all pages
+- ``front.mu`` - Front page listing all groups
+- ``group.mu`` - Group page listing repositories
+- ``repo.mu`` - Repository overview page
+- ``releases.mu`` - Release list page
+- ``release.mu`` - Release details page
+- ``tree.mu`` - File browser pages
+- ``blob.mu`` - File content display
+- ``commits.mu`` - Commit history listing
+- ``commit.mu`` - Individual commit detail page
+- ``refs.mu`` - Branches and tags listing
+- ``stats.mu`` - Statistics page
+
+Templates can include the following variables:
+
+- ``{PAGE_CONTENT}`` - The main content of the page (required)
+- ``{NODE_NAME}`` - The configured node name
+- ``{NAVIGATION}`` - Breadcrumb navigation links
+- ``{VERSION}`` - The rngit version number
+- ``{GEN_TIME}`` - Page generation time
+
+**Dynamic Templates**
+
+Templates can be made executable to generate dynamic content. If a template file has the executable bit set, it will be executed and its stdout used as the template content.
+
+**Icon Sets**
+
+By default, the page server uses Nerd Font icons. If you prefer simpler icons or your terminal does not support Nerd Fonts, you can enable Unicode icons instead:
+
+.. code:: text
+
+  [pages]
+  serve_nomadnet = yes
+  unicode_icons = yes
+
+**Repository Statistics**
+
+When statistics recording is enabled (see the ``record_stats`` configuration option), the page server can display activity charts for each repository. The statistics page shows:
+
+- Total and peak views, fetches and pushes
+- Daily activity charts over a 90-day period
+- Combined activity visualization
+
+To view statistics, a user must have the ``s`` (stats) permission for the repository. See the Access Configuration section for details on setting permissions.
+
+**Repository Thanks**
+
+The page server includes a "Thanks" feature that allows users to express appreciation for a repository. On each repository page, a "Thanks" link is displayed showing the current thanks count. Clicking this link registers a thank you for the repository.
+
+**Configuration Example**
+
+A complete page server configuration might look like this:
+
+.. code:: text
+
+  [rngit]
+  node_name = My Git Server
+  announce_interval = 360
+  record_stats = yes
+
+  [repositories]
+  public = /var/git/public
+  internal = /var/git/internal
+
+  [access]
+  public = r:all
+  internal = rw:9710b86ba12c42d1d8f30f74fe509286
+
+  [pages]
+  serve_nomadnet = yes
+  unicode_icons = no
+
+
+Release Management
+==================
+
+In addition to hosting Git repositories, ``rngit`` provides a complete release management system. This allows you to publish versioned releases with associated artifacts, release notes and metadata. Releases are managed through the ``rngit release`` subcommand, and are also viewable through the Nomad Network page interface.
+
+**The Release Workflow**
+
+Creating a release involves specifying a Git tag and a directory containing build artifacts or other files to distribute. The ``rngit`` client will open your configured ``$EDITOR`` to compose release notes, then upload all artifacts to the remote repository node.
+
+To create a release, specify the tag name and path to artifacts:
+
+.. code:: text
+
+  $ rngit release create rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo v1.2.0:./dist
+
+This will:
+
+1. Verify that the tag ``v1.2.0`` exists in the repository
+2. Open your editor to write release notes
+3. Upload all files from the ``./dist`` directory
+4. Publish the release
+
+If no ``$EDITOR`` environment variable is set, ``rngit`` will try to use ``nano``, ``vim`` or ``vi``. The editor will show a template with instructions. Lines starting with ``#`` will be ignored, and if the remaining content is empty after stripping comments, the release creation will be cancelled.
+
+**Release Storage & Structure**
+
+Releases are stored on the server in a directory named ``repo_name.releases`` next to the bare repository. Each release is a subdirectory containing:
+
+- ``META`` - Release metadata in ConfigObj format
+- ``RELEASE.md`` or ``RELEASE.mu`` - Release notes
+- ``artifacts/`` - All uploaded files
+- ``THANKS`` - Appreciation count from users
+
+**Listing Releases**
+
+To view all releases for a repository:
+
+.. code:: text
+
+  $ rngit release list rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo
+
+  Tag          Status     Created              Objs  Notes
+  ------------------------------------------------------------------
+  v1.2.0       published  2025-01-15 14:32     3     Another release
+  v1.1.0       published  2024-12-03 09:15     2     Bug fix release
+  v1.0.0       published  2024-10-20 16:45     2     Initial release
+
+**Viewing Release Details**
+
+To see full information about a specific release:
+
+.. code:: text
+
+  $ rngit release view rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo v1.2.0
+
+  Release : 0.9.2

+    - myapp-1.2.0.tar.gz (1.5 MB)
+    - myapp-1.2.0.zip (1.6 MB)
+    - checksums.txt (256 B)
+
+**Deleting Releases**
+
+To remove a release:
+
+.. code:: text
+
+  $ rngit release delete rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo v1.2.0
+
+  Are you sure you want to delete release 'v1.2.0'? [y/N]: y
+  Release v1.2.0 deleted
+
+**Requirements & Validation**
+
+- The specified tag must exist in the remote repository
+- You must have ``release`` permission for the repository
+- The target artifacts directory must exist and contain at least one file
+- Release notes cannot be empty
+
+**Permissions**
+
+Release management requires the ``release`` permission, configured the same way as other repository permissions. In the config file or ``.allowed`` files, use ``rel:target`` to grant release management rights:
+
+.. code:: text
+
+  # In .allowed file or config
+  rel:all          # Allow everyone
+  rel:9710b86...   # Allow specific identity
+  rel:none         # Deny everyone
+
+**Nomad Network Interface**
+
+When the Nomad Network page server is enabled, releases are displayed on a dedicated releases page for each repository. Each release is listed with its tag, creation date, artifact count and a preview of the release notes. Clicking a release shows the full details including formatted release notes and a listing of all artifacts with their sizes.
+
+Only releases with ``published`` status are visible through the Nomad Network interface. Draft releases (if supported in future implementations) would only be visible through the command-line interface.
+
+**All Command-Line Options (rngit release)**
+
+.. code:: text

+The rngit Utility
+=================
+
+The ``rngit`` utility provides full Git repository hosting and interaction over Reticulum, as well as many other useful features for software development, collaboration and publishing. It allows you to host Git repositories on Reticulum nodes, interact with remote repositories using standard Git commands through the ``rns://`` URL scheme, and to publish software releases.
+
+The system consists of two parts: The ``rngit`` node that hosts and manages repositories, and the ``git-remote-rns`` helper that enables Git to communicate with rngit nodes. As soon as you have RNS installed on your system, you can transparently use Git with Reticulum-hosted repositories just like any other type of remote. Git over Reticulum uses URLs in the following format: ``rns://DESTINATION_HASH/group/repo``.
+
+If you set a branch to track a Reticulum remote as the default upstream, you can simply use ``git`` as you normally would; all commands work transparently and as expected.
+
+.. warning::
+   **The rngit program is a new addition to RNS!** This functionality was introduced in RNS 1.2.0. While great care has been taken to design a secure, but highly configurable and flexible permission system for allowing many users to interact with many different repositories on a single node, ``rngit`` has not been tested extensively in the wild! Be careful when hosting repositories, especially if they are public or semi-public.
+
+For the full documentation on the `rngit` system, see the :ref:`Using Git Over Reticulum<git-main>` chapter of this manual.

+The rnsh Utility
+================
+
+The ``rnsh`` utility provides a fully interactive remote shell over Reticulum.
+It allows you to establish encrypted, authenticated shell sessions on remote
+systems, complete with terminal emulation, pipe support, and window resizing.
+
+While the ``rnx`` utility is useful for simple remote command execution and
+retrieving output, ``rnsh`` provides a complete interactive terminal experience,
+making it ideal for remote administration and management tasks that require
+real-time interaction, just like SSH does for IP networks.
+
+``rnsh`` operates in two modes: a *listener* mode that accepts incoming
+connections, and an *initiator* mode that connects to a remote listener. Both
+sides authenticate using Reticulum Identities, ensuring that only authorised
+peers can establish sessions.
+
+.. note::
+   ``rnsh`` provides a genuine interactive terminal over Reticulum. It supports
+   full terminal emulation including escape sequences, window resizing, signal
+   forwarding, and piping of standard input, output and error streams. This
+   makes it suitable for running text editors, terminal multiplexers, and any
+   other interactive programs on remote systems.
+
+**Usage Examples**
+
+Start ``rnsh`` in listener mode, accepting connections from specific identities:
+
+.. code:: text
+
+  $ rnsh -l -a 941bed5e228775e5a8079fc38b1ccf3f -a 1b03013c25f1c2ca068a4f080b844a10
+
+You can also specify allowed identity hashes (one per line) in the file
+``~/.rnsh/allowed_identities`` or ``~/.config/rnsh/allowed_identities``, and
+simply run the program in listener mode:
+
+.. code:: text
+
+  $ rnsh -l
+
+Connect to a remote listener from another system:
+
+.. code:: text
+
+  $ rnsh 7a55144adf826958a9529a3bcf08b149
+
+Specify a command to run on the remote system, separating ``rnsh`` options from
+the remote command with ``--``:
+
+.. code:: text
+
+  $ rnsh 7a55144adf826958a9529a3bcf08b149 -- top
+
+Set a default command for the listener, in case the initiator does not supply
+one, or when remote command execution is disabled:
+
+.. code:: text
+
+  $ rnsh -l -- /bin/bash --login
+
+Use the ``-m`` flag to mirror the exit code of the remote process:
+
+.. code:: text
+
+  $ rnsh -m 7a55144adf826958a9529a3bcf08b149 -- /usr/local/bin/check-status
+
+Use the ``-p`` flag to display the identity and destination hash for a listener:
+
+.. code:: text
+
+  $ rnsh -l -p
+
+  Identity     : <984b74a3f768bef236af4371e6f248cd>
+  Listening on : 7a55144adf826958a9529a3bcf08b149
+
+Use a specific identity file rather than the default:
+
+.. code:: text
+
+  $ rnsh -l -i /path/to/identity
+
+Announce the listener destination on startup, and periodically:
+
+.. code:: text
+
+  $ rnsh -l -b 900
+
+The ``-b`` option specifies the announce period in seconds. Use ``0`` to
+announce only once at startup.
+
+**Authentication & Authorisation**
+
+By default, ``rnsh`` requires that connecting initiators identify themselves
+with a Reticulum Identity whose hash is present in the list of allowed
+identities. Allowed identities can be specified on the command line with the
+``-a`` option, and can be used multiple times:
+
+.. code:: text
+
+  $ rnsh -l -a 941bed5e228775e5a8079fc38b1ccf3f -a 1b03013c25f1c2ca068a4f080b844a10
+
+You can also maintain a list of allowed identity hashes in the file
+``~/.rnsh/allowed_identities`` or ``~/.config/rnsh/allowed_identities``,
+with one hex hash per line. This file is reloaded every time a new connection
+is received, so changes take effect immediately without restarting ``rnsh``.
+
+If you want to accept connections from any identity (for testing or in fully
+trusted environments), you can disable authentication with the ``-n`` option:
+
+.. code:: text
+
+  $ rnsh -l -n
+
+.. warning::
+   Disabling authentication with ``-n`` means that **any** Reticulum peer that
+   can reach your listener will be able to execute commands on your system. Only
+   use this option if you *really* know what you're doing.
+
+**Remote Command Control**
+
+When running in listener mode, ``rnsh`` allows you to control how remote
+commands are handled:
+
+- By default, the listener accepts the command sent by the initiator. If the
+  initiator does not supply a command, the listener's default shell is used.
+
+- Use ``-C`` (``--no-remote-command``) to disable execution of commands received
+  from the initiator. Only the listener's default command (or the command
+  specified after ``--``) will be executed:
+
+.. code:: text
+
+  $ rnsh -l -C -- /usr/local/bin/safe-script
+
+- Use ``-A`` (``--remote-command-as-args``) to append the initiator's command
+  to the listener's default command instead of replacing it. This can be useful
+  for restricting the remote to a specific program while still allowing the
+  initiator to pass arguments:
+
+.. code:: text
+
+  $ rnsh -l -A -- /usr/bin/top
+
+**Service Names**
+
+When running in listener mode, ``rnsh`` uses a service name to differentiate
+between multiple listener instances that may share the same identity. By
+default, the service name is ``default``. You can specify a different service
+name with the ``-s`` option:
+
+.. code:: text
+
+  $ rnsh -l -s monitoring
+
+This allows you to run multiple listeners on the same node, each with a
+different service name and purpose.
+
+**Initiator Options**
+
+When connecting to a remote listener, several options are available:
+
+- Use ``-N`` (``--no-id``) to disable sending your identity to the remote
+  listener. Note that the listener must have authentication disabled (``-n``)
+  for the connection to succeed in this case.
+
+- Use ``-m`` (``--mirror``) to make the initiator return with the exit code of
+  the remote process, rather than always returning ``0``.
+
+- Use ``-w`` (``--timeout``) to specify the connection and request timeout in
+  seconds. By default, the timeout matches the Reticulum path request timeout.
+
+**Identity & Destination**
+
+The default identity file for ``rnsh`` is stored at
+``~/.reticulum/identities/rnsh``, but you can specify a different one with the
+``-i`` option, which will be created if it does not already exist:
+
+.. code:: text
+
+  $ rnsh -l -i /path/to/identity
+
+To display the identity and destination information for a listener, use the
+``-p`` option. When combined with ``-l``, both the identity and the listening
+destination hash are displayed:
+
+.. code:: text
+
+  $ rnsh -p
+
+  Identity     : <984b74a3f768bef236af4371e6f248cd>
+
+  $ rnsh -l -p
+
+  Identity     : <984b74a3f768bef236af4371e6f248cd>
+  Listening on : 7a55144adf826958a9529a3bcf08b149
+
+**Verbosity**
+
+Like other Reticulum utilities, ``rnsh`` supports the ``-v`` and ``-q`` flags
+to increase or decrease logging verbosity. Multiple flags can be specified to
+further adjust the log level. The default log level is ``INFO`` for listeners
+and ``ERROR`` for initiators.
+
+.. code:: text
+
+  $ rnsh -l -vv       # Listener with debug-level output
+  $ rnsh -q 7a55144adf826958a9529a3bcf08b149   # Quiet initiator
+
+By default, all log output is routed to ``~/.rnsh/logfile`` for initiators.
+
+**Escape Sequences**
+
+During an active ``rnsh`` session, the following escape sequences are
+available. These are only recognised immediately after a newline character:
+
+- ``~~`` - Send a literal tilde character
+- ``~.`` - Terminate the session and exit immediately
+- ``~L`` - Toggle line-interactive mode
+- ``~?`` - Display the escape sequence quick reference

+****************
+Zen of Reticulum
+****************
+
+The Illusion Of The Center
+==========================
+
+For the better part of a generation, we have been taught to visualize the digital world through the lens of hierarchy. The mental maps we carry are dominated by a single, misleading image: **The Cloud**.
+
+We imagine the network as a vast, ethereal space "up there" or "out there". A centralized repository of services and data to which we, the lowly clients, must connect. We build our software with this assumption hardcoded into our logic: *There is a server. The server has the authority. The server knows the way. I must find the server to function*.
+
+This is the Client-Server mental model, and it is the primary obstacle to understanding Reticulum.
+
+Fallacy Of The Cloud
+--------------------
+
+The first step in the Zen of Reticulum is to realize that *there is no cloud*. There is only other people's computers. When you build for the cloud, you are building *for* a landlord. You are accepting that your application's existence is conditional on the permission, uptime, and continued goodwill of a central authority.
+
+In Reticulum, you must shift your thinking from "connecting to" to "being among". Reticulum is not a service you subscribe to - *it is a fabric you inhabit*. There is no "up there". There is only *here* and *there*, and the space between them is peer-to-peer.
+
+Decentralization Or Uncentralizability?
+---------------------------------------
+
+It is common to hear the word "decentralized" thrown around in modern tech circles. But often, this is merely a marketing term for "slightly distributed centralization". A blockchain with a few dominant miners, or a federated protocol with a few giant servers. *In practice*, it's still centralized. It simply has a few centers instead of one.
+
+Reticulum goes further. It wants **Uncentralizability**.
+
+This is not a wishful political stance, but a foundational mathematical characteristic of the protocol, onto which everything else has been built. Reticulum assumes that every peer on the network is potentially hostile, and every link is potentially compromised. It is designed with no "privileged" nodes. While some nodes may act as Transport Instances - forwarding traffic for others - they do so *blindly*, and they only know about their immediate surroundings, and nothing more. They route based on cryptographic proofs, not on administrative privilege. They cannot see who is talking to whom, nor can they selectively manipulate traffic without breaking their own ability to route entirely.
+
+The system is designed to make hierarchy structurally impossible. You cannot hijack an address, because there is no central registry to hijack. You cannot block a user, because there is no central switch to flip. You can offer paths through the network, but you can't force anyone to use them.
+
+Death To The Address
+--------------------
+
+To break free of the center, you must also let go of the concept of the "Address".
+
+In the IP world, an address is a location. It is a coordinate in a *deeply hierarchical* and static grid. If you move your computer to a different house, your address changes. If your router reboots, your address might change. Your *identity* is bound to your *location*, and therefore, it is fragile, and easily controlled.
+
+Reticulum abolishes this link between *Identity* and *Location*.
+
+In Reticulum, an address is not a place; it is a **Hash of an Identity**. It is a cryptographic representation of *who* you are, not *where* you are. Because of this, your address is portable. You can take a laptop from a WiFi cafe in Berlin, to a LoRa mesh in the mountains, to a packet radio link on a boat, and your "address" - your *Destination Hash* - never changes.
+
+The network does not route to a place; it routes to a *person* (or a machine). When you send a packet, you are not targeting a coordinate in a grid; you are encrypting a message for a specific entity. The network dynamically discovers where that entity currently resides, and it does so in a way where no one really knows where that entity is actually located physically.
+
+**Consider:**
+
+- **The Old Way:** *"I am at* ``192.168.1.5``. *Come find me"*.
+- **The Zen Way:** *"I am* ``<327c1b2f87c9353e01769b01090b18f2>``. *Wherever I am, my peers can reach me"*.
+
+Once you stop thinking about servers and start thinking about portable identities, where everyone can always reach everyone else directly, the illusion of the center fades away. You realize there *is* no center holding the network together. No coordinators or bureaucrats required. The network is simply the sum of its peers, communicating directly, sovereignly, and without a master.
+
+
+Physics Of Trust
+================
+*Paranoia Is A Great Design Principle*
+
+If we accept that there is no center - that the network is a chaotic, peer-to-peer mesh - we are forced to confront a terrifying reality: **There is no one guarding the door**.
+
+In the traditional networking mindset, we rely on the concept of the "trusted core". We assume our local coffee shop WiFi is safe, or that the backbone providers are neutral custodians. We build our security like a castle: strong walls on the outside, soft and trusting on the inside. We use encryption only when we step out into the "wild" internet.
+
+Hostile Environments
+--------------------
+
+The Zen of Reticulum requires you to invert this. You must assume that *every* environment is hostile. This isn't cynicism, just uncaring physics.
+
+When you transmit information over radio waves, you are shouting into a crowded room. Anyone can listen. When you traverse the internet, your packets pass through routers controlled by strangers, corporations, and state actors. Assuming privacy in this environment without cryptographic protection is not optimism but gross negligence.
+
+Reticulum is built on the premise that every link is tapped, and every peer is a potential adversary. If your system cannot survive an adversary owning the physical layer, it cannot survive at all.
+
+But this is the paradox: By assuming the network is hostile, you make it safe. When you accept the dangers for what they are, they become manageable. When you stop trusting the infrastructure and start trusting the math, you eliminate the single point of failure: Human integrity.
+
+Encryption Is Not A Feature
+---------------------------
+
+In the world of TCP/IP, encryption is an afterthought. It is a layer we slap on top of the protocol (HTTPS, TLS) to patch the security holes of the original design. It is a "feature" you sometimes *enable* for "sensitive data". This is fundamentally flawed, since all data is sensitive.
+
+In Reticulum, encryption is **gravity**.
+
+It is not optional. It is not a plugin. It is the *fundamental force that allows the network to exist*. If you were to strip the encryption from Reticulum, the routing would break. The Transport system uses cryptographic signatures and entropy to verify paths and pass information. If packets were plaintext, intermediate nodes could not prove that a route was valid, nor could endpoints prevent spoofing or tampering.
+
+In Reticulum, the entropy of the encrypted packet *is* the routing logic.
+
+To ask for a version of Reticulum without encryption is like asking for a version of the ocean without liquid. You are not asking for a feature change; you're asking for a different physical universe. We design for a universe where information has mass, structure, and integrity.
+
+Zero-Trust Architectures
+------------------------
+
+We must unlearn our reliance on **Institutional Trust**.
+
+For decades, we have been trained to trust authorities. We trust a website because a chain of Certificate Authorities (companies we don't know) vouches for it. We trust an app because it is in an app store (run by a corporation we don't control). We trust a message because it comes from a phone number assigned by a telecom. Yet, everything in our digital information sphere today is more untrustworthy and risky than a medieval second-hand underwear market.
+
+Reticulum replaces institutional trust with **Cryptographic Proof**.
+
+In Reticulum, you do not trust a node because it has a nice hostname or because it is listed in a directory. You trust it because it holds the private key corresponding to the Destination Hash you are communicating with. This trust is binary, mathematical, and **absolute**. Either the signature matches, or it does not. There is no "maybe".
+
+This shift moves the power from the institution to the individual. You become the ultimate arbiter of your own trust relationships. You decide which keys to accept, which paths to follow, and which identities to recognize.
+
+**Consider:**
+
+- **The Old Way:** *"I trust this site because the browser says the lock icon is green"*.
+- **The Zen Way:** *"I trust this destination because I have verified its hash fingerprint out-of-band, and the math confirms the signature"*.
+
+When you internalize the Physics of Trust, you stop looking for protection from firewalls, VPNs, and Terms of Service agreements. You realize that true security comes from the design of the protocol itself. You can stop trusting the cloud, and you start trusting the code - because you can verify it yourself.
+
+
+Merits Of Scarcity
+==================
+*Every Bit Counts*
+
+We have grown addicted to abundance. In the modern digital ecosystem, bandwidth is treated as an endless, flat ocean. We stream high-definition video without a thought, we ship entire libraries of code just to render a single button, and we measure performance in gigabits per second. This abundance has hollowed out our craft. When constraints vanish, efficiency dies, and with it, a certain kind of Clarity and Quality.
+
+Reticulum asks you to step out of the ocean and onto the tightrope.
+
+The Bandwidth Fallacy
+---------------------
+
+The Zen of Reticulum requires the realization that **5 bits per second is a valid speed**.
+
+To a modern developer, this sounds like paralysis. But there is a profound freedom in limits: When you have a gigabit connection, you can be incredibly sloppy. You can be wasteful. You can push your problems onto the infrastructure. *"It’s slow? Get a faster router"*.
+
+But on a high-latency, low-bandwidth link (be it a noisy HF radio channel or a tenuous LoRa hop) you cannot push problems anywhere. You must solve them. The network does not negotiate with waste.
+
+This forces a shift from consumption to interaction. You are no longer, then, consuming a service provided by a fat pipe; you are engaging in a careful negotiation with the physical medium. The medium becomes a partner in the conversation, not just a dumb conduit. You suddenly need to *understand the world to be in it*.
+
+Cost Of A Byte
+--------------
+
+In a scarce economy, a byte is not just data, but energy, time, and space.
+
+Every byte you transmit consumes battery life on a solar-powered node. It occupies valuable airtime that could have been used by another peer. It represents a measurable slice of the electromagnetic spectrum.
+
+When you internalize this, you begin to write code differently. You stop asking, "How much data can I send?" and start asking, "What is the *minimum* amount of information required to convey this intent? How can I best utilize my informational entropy?"
+
+This is where the elegance of Reticulum shines. The protocol is designed to strip away the non-essential. A link establishment takes three very small packets. A destination hash fits in 16 bytes. The overhead is vanishingly small, leaving almost the entire channel for the message itself.
+
+**Consider:**
+
+- **The Old Way:** *"I need to send a status update. I'll send a JSON object with metadata, timestamps, and user profile info (15KB)."*
+- **The Zen Way:** *"I need to send a status update. I'll send a single byte representing the state code. The context is already known."*
+
+This is of course optimization, but more importantly, *it is a form of respect*. Efficiency in a shared medium is an act of stewardship. By taking only what you need from the network, you leave room for others. The network listens to those who speak with purpose.
+
+Flow & Time
+-----------
+
+Scarcity also teaches us about time. We have become addicted to the *synchronous* now - the instant ping, the real-time stream. But Reticulum embraces *asynchronous* time.
+
+When links are intermittent and latency is measured in minutes or hours, "real-time" is an illusion. Reticulum doesn't encourage **Store and Forward** as a mere fallback, but as a primary mode of existence. You write a message, it propagates when it can, and it arrives when it arrives.
+
+This changes the psychological texture of communication. It removes the anxiety of the immediate response. It allows for contemplation. You are not demanding the recipient's attention *right now*; you are placing a gift in their path, to be found when they are ready.
+
+By designing for delay, you design for resilience. You are no longer building a house of cards that collapses when a single packet drops. You are building a stone arch that distributes the load *over time*.
+
+Liberation From Limits
+----------------------
+
+There is a strange optimism in scarcity. When you are forced to work within strict constraints, you are forced to prioritize. *You* must decide what truly matters. *That* is the real core of agency.
+
+In the infinite fantasy world of The Cloud, everything is urgent, so nothing is. In the economy of Reticulum, the cost of transmission forces you to weigh the value of your message. Do you really need to send that heart beat? Is that photo essential?
+
+When you strip away the noise, what remains is *signal*.
+
+This discipline creates a different kind of developer. It creates a craftsman who understands that the best code is the code you don't have to write. It creates a user who understands that the most powerful message is the one that is *understood*, not the one that is loudest. In the world of Reticulum, you are not a mere consumer of bandwidth; you are an architect of intent.
+
+
+Sovereignty Through Infrastructure
+==================================
+**Be Your Own Network**
+
+We live in an era of digital tenancy. We lease our connectivity from ISPs. We rent our storage from cloud providers. We even borrow our identity from social media platforms. We are tenants in a house we did not build, governed by rules we did not write, subject to eviction at the whim of a landlord who has never met us.
+
+The Zen of Reticulum is the realization that you *can* own the house.
+
+A Carrier-Grade Fallacy
+-----------------------
+
+For decades, we have been gaslit into believing that networking is really not just hard, but impossible. It is presented as a dark art reserved for telcos and billionaires, requiring millions of dollars of fiber optics, climate-controlled data centers, and armies of engineers. We are told that building reliable infrastructure is "too complex" for the individual or small organization.
+
+This is a big, fat lie.
+
+Physics is simple. A radio wave needs a transmitter and a receiver. A packet needs a path. The "complexity" of the modern internet is largely bureaucratic - a mountain of billing systems, regulatory capture, and legacy cruft designed to keep the gatekeepers in power.
+
+Reticulum strips away the bureaucracy. It runs on hardware that costs the price of a dinner. It runs on spectrum that is free to use. It demonstrates that a robust, planetary-scale network does not require a Fortune 500 company. It requires only the will to deploy, and the distributed, uncoordinated efforts of many individuals.
+
+Personal Infrastructure
+-----------------------
+
+This is where the rubber meets the road. You can read about Reticulum, you can understand the theory, but the insights only arrive when you plug in a radio and run a Transport Node. Suddenly, you are no longer a consumer. You're an operator.
+
+This shift is subtle but profound. When you run your own infrastructure, the network ceases to be a service that is provided *to* you. It becomes a space that you *inhabit*. You become responsible for the flow of information. You gain an intimate understanding of the medium - the way the weather affects the radio waves, the way the topology changes, the way the packets dance through the ether.
+
+There is a quiet competence that comes from this. You stop asking "Is the internet down?" and start asking "Is *my* links up?" You stop waiting for a technician and start checking the logs. This is a form of strength. To understand the system that carries your words is to be free from the mystery that keeps you dependent.
+
+The Ability To Disconnect
+-------------------------
+
+Why go to the trouble? Why buy the radio, write the config, and leave the Pi running in the corner?
+
+Because the old, centralized network is fragile. And because most of us doesn't even really want to be there anymore.
+
+The internet we rely on today is a chain of single points of failure. Cut the undersea cable, and a continent goes dark. Shut down the power grid, and the cloud evaporates. Deprioritize the "wrong" traffic, and the flow of information is strangled.
+
+Sovereignty is the ability to survive the cut, whether or not that cut was an accident or on purpose.
+
+When you build your own infrastructure, you build a lifeline. Reticulum is designed to function over media that the traditional internet cannot touch - bare wires, battery-powered radios, ad-hoc WiFi meshes. When the grid fails, or the censors arrive, or the bill goes unpaid, your Reticulum network continues to hum.
+
+This is not about "dropping out" of society. It is about building a substrate on which an actual *Society* can function.
+
+**Consider:**
+
+- **The Old Way:** "My connection is slow. I should call my ISP and complain."
+- **The Zen Way:** "The path is noisy. I will adjust the antenna or find a better route."
+
+By taking ownership of the infrastructure, you take ownership of your voice. You stop shouting into someone else's megaphone and start building your own. The network is no longer something that happens to you; it is something you make happen.
+
+
+Identity and Nomadism
+=====================
+**A Fluid Self**
+
+In the old world, you are defined by your coordinates. If you are at ``34.109.71.5``, you're *here*. If you unplug the cable and walk down the street, you vanish. Your digital self evaporates because it was tethered to the wall. You are a ghost in the endless machinations of gears, levers and transistors, bound to the hardware, and those that own it.
+
+This creates a subtle, constant anxiety. We are terrified of disconnecting because, in the architecture of the old web, disconnecting is a kind of death.
+
+The Zen of Reticulum offers a different way to be.
+
+Portable Existence
+------------------
+
+In Reticulum, your identity is not a location, or a username granted by a service. It is a cryptographic key - a complex, unique mathematical signature that exists independently of the physical world. You can carry it only in your mind, if you want to.
+
+Think of it less like a street address and more like a name. *A true name*.
+
+If you travel from Berlin to Tokyo, you do not change your name. You are still you. The people who know you can still recognize you. Reticulum applies this principle to the network layer. Your Destination Hash is **invariant**. It travels with you, stored securely on your device, *immutable as a stone*.
+
+This changes the relationship between you and the machine. You are not "logged into" the network via a specific gateway. You *are* the endpoint. The network does not connect to a place; *it converges on you*.
+
+Roaming Nodes
+-------------
+
+This freedom introduces a new concept of time and space: **Nomadism**.
+
+Because your identity is portable, your connectivity can be fluid. You can be sitting at a desk connected to a fiber backbone one moment, and walking through a field connected only to a long-range LoRa mesh the next. To the rest of the network, nothing has changed. Your friends do not need to update your contact info. The messages they send do not bounce back. The network senses the shift in the medium and reroutes the flow of data automatically.
+
+You are no longer a stationary node in a fixed grid. You are a wanderer in a fluid medium.
+
+The interfaces - whether it is WiFi, Ethernet, Packet Radio, or a physical wire - is merely the clothing your node wears. You change it to suit the environment. Underneath, you remain the same. This is the liberation of the protocol. It treats the physical medium as a transient circumstance, not a definition of self.
+
+**Consider:**
+
+- **The Old Way:** *"I lost connection. I have to reconnect to the VPN to tell them where I am now."*
+- **The Zen Way:** *"I moved. The network subtly bends to accomodate this new reality."*
+
+Announcing Presence
+-------------------
+
+How does the network find a wanderer? It listens.
+
+In the IP world, we query directories. We ask a server, "Where is Mark?" The server checks its database and gives us a coordinate. This means that someone, somewhere, is keeping track of you. It assumes and *requires* surveillance.
+
+Reticulum replaces surveillance with **Announces**.
+
+Instead of asking a central authority where you are, you simply state your presence. You broadcast a cryptographic proof: "I am here, and I am who I say I am". This ripples out through the mesh. Your neighbors hear it, update their path tables, and pass it on.
+
+This is a quiet, organic process. It is the digital equivalent of lighting lanterns in the dark. You do not need to chase the light; you let the light find you. It respects your autonomy. You choose when to announce, how often to speak, and to whom. You also choose when to disappear - for but a moment or perpetually.
+
+Anchor In The Flow
+------------------
+
+There is a deep peace in this nomadism. It teaches you that stability does not come from standing still. Stability comes from *internal coherence*.
+
+By holding your own private key, you hold your own center of gravity. The world around you; the infrastructure, the topography and the availability of links can all shift chaotically. Storms can knock out towers. Cables can be cut. The internet can go down.
+
+But as long as you possess your key, you possess your identity. The entire infrastructure can be destroyed and rebuilt, and you are still you. Nothing lasts, yet nothing is lost.
+
+You become a sovereign entity moving through the noise, connected not by the rigidity of cables, but by the fluidity of recognition. The network becomes a place you inhabit, rather than a utility you subscribe to: You are at home in the ether.
+
+
+Ethics Of The Tool
+==================
+**Technology With Conscience**
+
+You have unlearned the center. You have accepted the physics of trust. You have embraced the economy of scarcity and the freedom of unbound nomadism. You are standing in a new space. Now, look at the tool in your hand.
+
+In the old world, we were taught that technology is neutral. We are told that "guns don't kill people, people do", or that a component is just a component, indifferent to what its combinatorial potential is. This is a convenient lie. It serves only to allow the builders to wash their hands of responsibility.
+
+But we know better now. We know that **architecture is politics**, and *politics is control*. The way you build a system determines how it will be used. If you build a system optimized for mass surveillance, you *will* get a panopticon. If you build a system optimized for centralized control, you *will* get a dictatorship. If you build a system optimized for extraction, you *will* get a parasite.
+
+The Zen of Reticulum asserts that a tool is never neutral.
+
+On the very contrary: A tool is intent, **crystallized**.
+
+The Harm Principle
+------------------
+
+Why does the Reticulum License forbid the software from being used in systems designed to harm humans? Is it not just a restriction on freedom?
+
+It is a restriction on *license*, yes, but it is an expansion of *freedom*.
+
+Building powerful tools without a moral compass is in no way virtuous or commendable, it is plain and simple irresponsibility.
+
+A tool that can easily be used to oppress is a real danger to the user. If you build a network that can be turned against you by a tyrant, you are not free. You are merely waiting for the leash to tighten. By encoding the "Harm Principle" into the legal DNA of the reference implementation, we are building a safeguard. We are stating, clearly and immutably, that *this tool* is for **life**, not for death.
+
+This aligns the software with the interests of humanity. It cements that the network cannot be conscripted into a kill-system, a weaponized drone controller, or a torture device without breaking the license and the law. It is a line drawn in the sand - not by a government or external authority, but by the creators of the tool itself.
+
+**Consider:**
+
+- **The Old Way:** *"It's just software. How people use it is not my problem."*
+- **The Zen Way:** *"This software is a habitat. I will not allow it to be used to build a cage."*
+
+It is *your* choice whether to align with this - we are not forcing this stance on anyone. If you choose to align with life over death, with creativity over destruction, we grant you an immensely powerful tool, to own and build with as you please. If you do not, we deny it.
+
+If you do not like this, we most assuredly do not need you here, and you are on your own.
+
+Public Domain Protocol
+----------------------
+
+This leads to a vital distinction: The difference between the *idea* and the *implementation*.
+
+The protocol - the mathematical rules of how Reticulum works - is dedicated to the Public Domain. It belongs to humanity. **No one can own it**. Anyone can implement it, improve it, or adapt it. This is the core idea of free communication, which itself must be forever free.
+
+But the functional, deployed *reference implementation* - the Python code, the maintenance, the years of labor - has a conscience. This distinction is the engine of sustainability. It allows the protocol to be universal, while ensuring that the specific labor of the builders is not hijacked to undermine the foundational intent of the project itself. From this document, it should be very clear what this intent is.
+
+If you want to build a system with Reticulum that manipulates and damages users for profits or targets missiles, you can use the public domain protocol, and start from scratch. But you cannot take our work. You must do your own. This serves as a pillar of accountability. If you want to build a weapon, *you* go and forge the steel yourself, while the world observes. And when the blood is drawn - it is on **your** hands.
+
+Preserving Human Agency
+-----------------------
+
+We live in an era of predatory extraction. The open-source commons is being scraped, ingested, and regurgitated by machine learning algorithms, whose corporate owners seek to replace the very humans who built those commons. Our code, our words, and our creativity is being used to train systems that are specifically designed to make us obsolete, without offering anything else in return than serfdom and leashes.
+
+Reticulum stands against this.
+
+The license protects the software from being used to feed the beast. It draws a hard line: This tool is for *people*. It is for human-to-human connection. It is not a dataset to be strip-mined for the purpose of building a synthetic overlord, puppeteered by a miniscule conglomerate of controllers.
+
+This is a radical act of preservation. By protecting the code from AI appropriation, we are protecting space for human agency. We are ensuring that there remains a digital realm where the actors are flesh, blood and soul, where decisions are made by minds, not overlords hiding behind models.
+
+When you use Reticulum, you are using a tool that respects you. It does not see you as a product to be tracked. It does not see your data as fuel for an algorithm. It sees you as a sovereign, equal peer.
+
+This changes the foundational premise of using the technology. It restores dignity to the interaction. You are not the user of a service; you are a participant in a mutual covenant. The tool aligns with your autonomy, rather than eroding it.
+
+In this way, ethics is not a restriction, but a foundation. It is the foundation that helps ensure the network will still belong to you tomorrow.
+
+
+Design Patterns For Post-IP Systems
+===================================
+**Practical Philosophy for Developers**
+
+The philosophy is useless if it cannot be hammered into code. The metaphors we have explored - nomadism, scarcity, trust - are not just poetry, but real-world engineering constraints. When you sit down to write software for Reticulum, these concepts must shape the very structure of your application.
+
+We are now moving from the *why* to the *how*. This is where the abstract becomes concrete, and where you will see the true depth of the patterns we have been weaving.
+
+Store & Forward
+---------------
+
+The web has trained us to be impatient. We write synchronous code. We fire a request and we wait, blocking the UI, holding our breath. If the response doesn't come in 250 milliseconds, we show a spinner. If it doesn't come in five seconds, we show an error. We treat network connectivity as a binary state: either we are "online" or we are "broken".
+
+This is brittle. It is a rejection of reality.
+
+In Reticulum, connectivity is a spectrum, and presence is asynchronous. If at all applicable to your intent, you must design your applications to embrace **Store & Forward**.
+
+Instead of demanding an immediate answer, your application should act as a patient participant. You create a message for someone or something in the mesh. The network holds it. It carries it from node to node, perhaps over hours or days, waiting for the recipient to appear. When they finally surface, the message is delivered. This requires a shift from "request/response" to "event/handler". How exactly you do this is a challenge for you to solve intelligently within your problem domain, but Reticulum-based systems already exist that does this extremely well, and you can use them for inspiration.
+
+**Consider:**
+
+- **The Old Way:** ``Connect() -> Send() -> Wait() -> Crash if timeout.``
+- **The Zen Way:** ``Send() -> Continue living. -> Receive() when it arrives.``
+
+This changes the user experience profoundly. It removes the anxiety of the loading bar. It creates a sense of continuity. The user is not "waiting for the network"; they are interacting with a persistent log of communication that lives in the network itself.
+
+Naming Is Power
+---------------
+
+In the IP world, we are slaves to the Domain Name System. We rely on a hierarchy of registrars to map human-readable names to machine-readable addresses. This hierarchy is a choke point. If the registrar revokes your domain, or if the DNS server goes down, you vanish.
+
+Reticulum dissolves this hierarchy with **Hash-based Identity**.
+
+In this design pattern, a name is not a string you look up; it is a cryptographic destination you verify. When you design for Reticulum, you stop asking the user for a URL and start asking for a Destination or Identity Hash.
+
+This feels strange at first. A hash like ``<83b7328926fed0d2e6a10a7671f9e237>`` looks alien compared to ``myfriend.com``. But that alienness is the armor. It **cannot** be spoofed. It **cannot** be censored by a registrar. It is **absolute**.
+
+Designing for this means shifting your UI metaphors. You are no longer browsing a web of pages; you are managing a ledger of keys. You are building an "Address Book" that is actually a keyring. The names are given by the user, and the power stays with them. That hashes look complex is directly analogous to the strengths of the bonds formed by their use. It forces the user to engage in a moment of verification, an out-of-band handshake, which restores the human element of trust that SSL certificates stripped away.
+
+The Interface Is The Medium
+---------------------------
+
+One of the most liberating patterns in Reticulum is **Transport Agnosticism**.
+
+In traditional networking, your code is often littered with transport logic. "Am I on WiFi? Check bandwidth. Am I on Cellular? Check data plan. Am I on Ethernet?". You are constantly micromanaging the pipe.
+
+In Reticulum, you write to the API, and the API writes to the medium. You send a packet to a Destination. You do not care if that packet travels over a TCP tunnel, a LoRa radio wave, or a serial wire interface. That is the stack's concern.
+
+This allows you to write **Universal Applications**.
+Imagine a messaging app. You write it once. It works on a laptop connected to fiber. It works on a phone in the city using WiFi. And, without a single line of code changed, it works on a device in the wilderness, talking only to other devices via radio.
+
+The pattern is simple: **Never code to the hardware. Code to the intent.**
+
+**Consider:**
+
+- **The Old Way:** ``socket.connect(ip, port)``, and then a whole lot more
+- **The Zen Way:** ``RNS.Packet(destination, data).send()``
+
+By abstracting the medium, you make your software immortal to changes in infrastructure. The user might switch from a 4G hotspot to a HF modem tomorrow. Your software doesn't need to know. It simply continues the conversation.
+
+Emergent Patterns
+-----------------
+
+When you combine these patterns - *Store & Forward*, *Hash-based Identity*, and *Transport Agnosticism* - you create software that feels fundamentally different.
+
+It feels *grounded*. It doesn't flicker when the signal drops. It doesn't panic when the server is down. It has weight. It has persistence. It has *relevance*.
+
+You are no longer building a "client" that begs a "server" for attention. You are building an autonomous agent that exists within the mesh. It speaks when it needs to, listens when it can, and carries its identity with it wherever it goes.
+
+This is the culmination of the Zen. The code is not just a set of instructions: It is a behavioral envelope. It is a way of *being* in the network.
+
+
+Fabric Of The Independent
+=========================
+
+We have stripped away the illusions. We have seen that the center is empty, that trust *must* be hard, that resources are finite, and that we must own our infrastructure. We have seen that tools have ethics and that our identity can move fluidly.
+
+This is a reclaiming of the commons. For too long, we have allowed the most vital substrate of human society - *our ability to speak to one another* - to be colonized by entities that do not share our interests. We have allowed the architecture of our communication to be designed by accountants rather than architects.
+
+We are taking it back. Not by petitioning the masters, but by building the new world within, over, under and around the shell of the old.
+
+The Work Is Finished
+--------------------
+
+The heavy lifting is done.
+
+The protocol is in the public domain, a gift to humanity that can never be taken away. The software is written, tested, and running on devices scattered across the globe. The manual lies open before you. The source code for the reference implementation is now distributed on hundreds of thousands of devices across the planet. No one can delete or destroy it. The hardware is accessible and abundant.
+
+It was a hard road to get here, but we got here. Now, there is no roadmap committee waiting for approval. There is no venture capital dictating the user experience. There is no CEO to sign off on the next feature release.
+
+There is only you.
+
+The barrier to entry is no longer complexity: It is the mere habit of dependency. You were conditioned to wait. Wait for the app update. Wait for the ISP to fix the line. Wait for the platform to allow the post. Wait for the government to change the policies. Wait for the likes. Wait for the revolution to be televised.
+
+The revolution never was televised.
+
+It is packetized.
+
+Open Sky
+--------
+
+The future of this technology is a construction project.
+
+It looks like a single node on a windowsill, listening to the static. It looks like a message sent to a neighbor, bypassing the noise of the commercial web. It looks like a community mesh that grows, link by link, hop by hop, carried by hands that care more about connection than profit.
+
+You have the blueprints. You have the tools. You have the philosophy. The noise of the old world has fallen away, leaving you with the quiet clarity of the open spectrum.
+

+<p>A set of utilities for distributed collaborative software development and publishing is included in RNS.</p>
+<p>The system consists of two parts: The <code class="docutils literal notranslate"><span class="pre">rngit</span></code> node that hosts repositories, and the <code class="docutils literal notranslate"><span class="pre">git-remote-rns</span></code> helper that enables Git to communicate with rngit nodes. As soon as you have RNS installed on your system, you can transparently use Git with Reticulum-hosted repositories just like any other type of remote. Git over Reticulum uses URLs in the following format: <code class="docutils literal notranslate"><span class="pre">rns://DESTINATION_HASH/group/repo</span></code>.</p>
+<p>If you set a branch to track a Reticulum remote as the default upstream, you can simply use <code class="docutils literal notranslate"><span class="pre">git</span></code> as you normally would; all commands work transparently and as expected.</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p><strong>The rngit program is a new addition to RNS!</strong> This functionality was introduced in RNS 1.2.0. While great care has been taken to design a secure, but highly configurable and flexible permission system for allowing many users to interact with many different repositories on a single node, <code class="docutils literal notranslate"><span class="pre">rngit</span></code> has not been tested extensively in the wild! Be careful when hosting repositories, especially if they are public or semi-public.</p>
+</div>
+<section id="the-rngit-utility">
+<h2>The rngit Utility<a class="headerlink" href="#the-rngit-utility" title="Link to this heading">¶</a></h2>
+<p>The <code class="docutils literal notranslate"><span class="pre">rngit</span></code> utility provides full Git repository hosting and interaction over Reticulum. It allows you to host and manage Git repositories and releases on Reticulum nodes, and to interact with remote repositories using standard Git commands through the <code class="docutils literal notranslate"><span class="pre">rns://</span></code> URL scheme.</p>
+<p><strong>Usage Examples</strong></p>
+<p>Run <code class="docutils literal notranslate"><span class="pre">rngit</span></code> to start a repository node:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rngit
+
+[Notice] Starting Reticulum Git Node...
+[Notice] Reticulum Git Node listening on &lt;0d7334d411d00120cbad24edf355fdd2&gt;
+</pre></div>
+</div>
+<p>On the first run, <code class="docutils literal notranslate"><span class="pre">rngit</span></code> will create a default configuration file. You will then need to edit this, to point to your repository locations, configure access permissions, and perform any other necessary configuration.</p>
+<p>View your identity and destination hashes:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rngit --print-identity
+
+Git Peer Identity         : &lt;959e10e5efc1bd9d97a4083babe51dea&gt;
+Repository Node Identity  : &lt;153cb870b4665b8c1c348896292b0bad&gt;
+Repositories Destination  : &lt;0d7334d411d00120cbad24edf355fdd2&gt;
+</pre></div>
+</div>
+<p>If the page server is enabled, the output will also include the Nomad Network destination hash.</p>
+<p>You can run <code class="docutils literal notranslate"><span class="pre">rngit</span></code> in service mode with logging to file:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rngit -s
+</pre></div>
+</div>
+<p>Clone a repository from a remote <code class="docutils literal notranslate"><span class="pre">rngit</span></code> node:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ git clone rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo
+</pre></div>
+</div>
+<p>Add a Reticulum remote to an existing repository:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ git remote add some_remote rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo

+<h2>Repository Structure<a class="headerlink" href="#repository-structure" title="Link to this heading">¶</a></h2>
+<p>The <code class="docutils literal notranslate"><span class="pre">rngit</span></code> node organizes repositories into groups. Each group is a directory containing bare Git repositories. The repository path format is <code class="docutils literal notranslate"><span class="pre">group_name/repo_name</span></code>. For example, a repository at <code class="docutils literal notranslate"><span class="pre">/var/git/public/myrepo</span></code> would be accessible as <code class="docutils literal notranslate"><span class="pre">public/myrepo</span></code> via the URL <code class="docutils literal notranslate"><span class="pre">rns://DESTINATION_HASH/public/myrepo</span></code>.</p>
+<p><strong>Configuration</strong></p>
+<p>The <code class="docutils literal notranslate"><span class="pre">rngit</span></code> node configuration file is located at <code class="docutils literal notranslate"><span class="pre">~/.rngit/config</span></code> (or <code class="docutils literal notranslate"><span class="pre">/etc/rngit/config</span></code> for system-wide installations). The default configuration includes:</p>
+<ul class="simple">
+<li><p>Repository group paths defining where to find bare repositories</p></li>
+<li><p>Access permissions for groups and individual repositories</p></li>
+<li><p>Announce intervals for network visibility</p></li>
+<li><p>Optional statistics recording for repository activity</p></li>
+</ul>
+<p>Access permissions can be configured at the group level in the config file, or per-repository using <code class="docutils literal notranslate"><span class="pre">.allowed</span></code> files. Permissions use the format <code class="docutils literal notranslate"><span class="pre">permission:target</span></code> where permission is <code class="docutils literal notranslate"><span class="pre">r</span></code> (read), <code class="docutils literal notranslate"><span class="pre">w</span></code> (write), <code class="docutils literal notranslate"><span class="pre">rw</span></code> (read/write), <code class="docutils literal notranslate"><span class="pre">c</span></code> (create) or <code class="docutils literal notranslate"><span class="pre">s</span></code> (stats) and target is <code class="docutils literal notranslate"><span class="pre">all</span></code>, <code class="docutils literal notranslate"><span class="pre">none</span></code>, or a specific identity hash.</p>
+<p>The <code class="docutils literal notranslate"><span class="pre">s</span></code> (stats) permission allows viewing repository activity statistics, including views, fetches and pushes over time. To enable statistics recording, set <code class="docutils literal notranslate"><span class="pre">record_stats</span> <span class="pre">=</span> <span class="pre">yes</span></code> in the <code class="docutils literal notranslate"><span class="pre">[rngit]</span></code> section of the configuration file. You can also exclude specific identities from statistics by adding their hashes to <code class="docutils literal notranslate"><span class="pre">stats_ignore_identities</span></code>.</p>
+<p>Repository-specific <code class="docutils literal notranslate"><span class="pre">.allowed</span></code> files can be static text files or executable scripts that output permission rules to stdout. A <code class="docutils literal notranslate"><span class="pre">group.allowed</span></code> file in a repository group directory applies to all repositories within that group.</p>

+<h2>Serving Pages Over Nomad Network<a class="headerlink" href="#serving-pages-over-nomad-network" title="Link to this heading">¶</a></h2>
+<p>In addition to providing Git repository access via the Git remote helper protocol, <code class="docutils literal notranslate"><span class="pre">rngit</span></code> can also run a <a class="reference external" href="https://github.com/markqvist/nomadnet">Nomad Network</a> compatible page node. This allows users to browse repository information, view file contents, inspect commit history and access repository statistics through any Nomad Network client.</p>
+<p>When enabled, the page node provides a complete interface to your repositories, with automatic Markdown to Micron conversion, syntax-highlighted code browsing, and detailed commit, diff and statistics views.</p>
+<p><strong>Enabling the Git Page Node</strong></p>
+<p>To enable the page node, add the following to your <code class="docutils literal notranslate"><span class="pre">~/.rngit/config</span></code> file:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>[pages]
+serve_nomadnet = yes
+</pre></div>
+</div>
+<p>When the page node is enabled, <code class="docutils literal notranslate"><span class="pre">rngit</span></code> will listen on a Nomad Network node destination in addition to the Git repository destination. You can view the destination hash by running:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rngit --print-identity
+
+Git Peer Identity         : &lt;959e10e5efc1bd9d97a4083babe51dea&gt;

+Repositories Destination  : &lt;0d7334d411d00120cbad24edf355fdd2&gt;
+Nomad Network Destination : &lt;50824b711717f97c2fb1166ceddd5ea9&gt;
+</pre></div>
+</div>
+<p><strong>Accessing Repository Pages</strong></p>
+<p>Once the page server is running, you can access it from any Nomad Network client by connecting to the Nomad Network destination. The page node provides the following views:</p>
+<ul class="simple">
+<li><p><strong>Front Page</strong> - Lists all repository groups accessible to your identity</p></li>
+<li><p><strong>Group Page</strong> - Shows all repositories within a group</p></li>
+<li><p><strong>Repository Page</strong> - Displays repository overview, description and README</p></li>
+<li><p><strong>Releases</strong> - List of releases for the repository, with information and downloads</p></li>
+<li><p><strong>File Browser</strong> - Browse directory trees and view and download file contents</p></li>
+<li><p><strong>Commits View</strong> - View commit history with pagination</p></li>
+<li><p><strong>Commit Details</strong> - Detailed commit information with file changes and diffs</p></li>
+<li><p><strong>Refs View</strong> - List branches and tags</p></li>
+<li><p><strong>Statistics</strong> - Activity charts showing views, fetches and pushes over time</p></li>
+</ul>
+<p>All pages respect the same permission system used for Git access. If an identity does not have read access to a repository, they will not be able to view its pages.</p>

+<section id="formatting-syntax-highlighting">
+<h2>Formatting &amp; Syntax Highlighting<a class="headerlink" href="#formatting-syntax-highlighting" title="Link to this heading">¶</a></h2>
+<p>If the <code class="docutils literal notranslate"><span class="pre">pygments</span></code> Python module is installed on your system, the page server will automatically apply syntax highlighting to code files. The highlighting supports a wide range of programming languages and uses a color theme optimized for terminal display.</p>
+<p>To enable syntax highlighting, install pygments:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>pip install pygments
+</pre></div>
+</div>
+<p><strong>Markdown &amp; Micron Support</strong></p>
+<p>README files and other Markdown documents are automatically converted to Micron markup for display in Nomad Network clients. You can also write your README files directly in Micron, in which case they will display and render as such in any Nomad Network client. The file browser also supports viewing both rendered and raw Markdown and Micron documents.</p>
+<p>Code blocks in Markdown can include language hints for syntax highlighting:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>```python
+def hello_world():
+    print(&quot;Hello, Reticulum!&quot;)

+</section>
+<section id="customizing-templates">
+<h2>Customizing Templates<a class="headerlink" href="#customizing-templates" title="Link to this heading">¶</a></h2>
+<p>The page server uses a template system that allows complete customization of the generated pages. Templates are stored in the <code class="docutils literal notranslate"><span class="pre">~/.rngit/templates/</span></code> directory as Micron files.</p>
+<p>The following template files are supported:</p>
+<ul class="simple">
+<li><p><code class="docutils literal notranslate"><span class="pre">base.mu</span></code> - Base template wrapping all pages</p></li>
+<li><p><code class="docutils literal notranslate"><span class="pre">front.mu</span></code> - Front page listing all groups</p></li>
+<li><p><code class="docutils literal notranslate"><span class="pre">group.mu</span></code> - Group page listing repositories</p></li>

+<li><p><code class="docutils literal notranslate"><span class="pre">stats.mu</span></code> - Statistics page</p></li>
+</ul>
+<p>Templates can include the following variables:</p>
+<ul class="simple">
+<li><p><code class="docutils literal notranslate"><span class="pre">{PAGE_CONTENT}</span></code> - The main content of the page (required)</p></li>
+<li><p><code class="docutils literal notranslate"><span class="pre">{NODE_NAME}</span></code> - The configured node name</p></li>

+<li><p><code class="docutils literal notranslate"><span class="pre">{GEN_TIME}</span></code> - Page generation time</p></li>
+</ul>
+<p><strong>Dynamic Templates</strong></p>
+<p>Templates can be made executable to generate dynamic content. If a template file has the executable bit set, it will be executed and its stdout used as the template content.</p>
+<p><strong>Icon Sets</strong></p>
+<p>By default, the page server uses Nerd Font icons. If you prefer simpler icons or your terminal does not support Nerd Fonts, you can enable Unicode icons instead:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>[pages]
+serve_nomadnet = yes
+unicode_icons = yes
+</pre></div>
+</div>
+<p><strong>Repository Statistics</strong></p>
+<p>When statistics recording is enabled (see the <code class="docutils literal notranslate"><span class="pre">record_stats</span></code> configuration option), the page server can display activity charts for each repository. The statistics page shows:</p>
+<ul class="simple">
+<li><p>Total and peak views, fetches and pushes</p></li>
+<li><p>Daily activity charts over a 90-day period</p></li>
+<li><p>Combined activity visualization</p></li>
+</ul>
+<p>To view statistics, a user must have the <code class="docutils literal notranslate"><span class="pre">s</span></code> (stats) permission for the repository. See the Access Configuration section for details on setting permissions.</p>
+<p><strong>Repository Thanks</strong></p>
+<p>The page server includes a “Thanks” feature that allows users to express appreciation for a repository. On each repository page, a “Thanks” link is displayed showing the current thanks count. Clicking this link registers a thank you for the repository.</p>
+<p><strong>Configuration Example</strong></p>
+<p>A complete page server configuration might look like this:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>[rngit]

+<h2>Release Management<a class="headerlink" href="#release-management" title="Link to this heading">¶</a></h2>
+<p>In addition to hosting Git repositories, <code class="docutils literal notranslate"><span class="pre">rngit</span></code> provides a complete release management system. This allows you to publish versioned releases with associated artifacts, release notes and metadata. Releases are managed through the <code class="docutils literal notranslate"><span class="pre">rngit</span> <span class="pre">release</span></code> subcommand, and are also viewable through the Nomad Network page interface.</p>
+<p><strong>The Release Workflow</strong></p>
+<p>Creating a release involves specifying a Git tag and a directory containing build artifacts or other files to distribute. The <code class="docutils literal notranslate"><span class="pre">rngit</span></code> client will open your configured <code class="docutils literal notranslate"><span class="pre">$EDITOR</span></code> to compose release notes, then upload all artifacts to the remote repository node.</p>
+<p>To create a release, specify the tag name and path to artifacts:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rngit release create rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo v1.2.0:./dist

+<p>This will:</p>
+<ol class="arabic simple">
+<li><p>Verify that the tag <code class="docutils literal notranslate"><span class="pre">v1.2.0</span></code> exists in the repository</p></li>

+<li><p>Upload all files from the <code class="docutils literal notranslate"><span class="pre">./dist</span></code> directory</p></li>
+<li><p>Publish the release</p></li>
+</ol>
+<p>If no <code class="docutils literal notranslate"><span class="pre">$EDITOR</span></code> environment variable is set, <code class="docutils literal notranslate"><span class="pre">rngit</span></code> will try to use <code class="docutils literal notranslate"><span class="pre">nano</span></code>, <code class="docutils literal notranslate"><span class="pre">vim</span></code> or <code class="docutils literal notranslate"><span class="pre">vi</span></code>. The editor will show a template with instructions. Lines starting with <code class="docutils literal notranslate"><span class="pre">#</span></code> will be ignored, and if the remaining content is empty after stripping comments, the release creation will be cancelled.</p>
+<p><strong>Release Storage &amp; Structure</strong></p>
+<p>Releases are stored on the server in a directory named <code class="docutils literal notranslate"><span class="pre">repo_name.releases</span></code> next to the bare repository. Each release is a subdirectory containing:</p>
+<ul class="simple">
+<li><p><code class="docutils literal notranslate"><span class="pre">META</span></code> - Release metadata in ConfigObj format</p></li>
+<li><p><code class="docutils literal notranslate"><span class="pre">RELEASE.md</span></code> or <code class="docutils literal notranslate"><span class="pre">RELEASE.mu</span></code> - Release notes</p></li>

+<p><strong>Requirements &amp; Validation</strong></p>
+<ul class="simple">
+<li><p>The specified tag must exist in the remote repository</p></li>
+<li><p>You must have <code class="docutils literal notranslate"><span class="pre">release</span></code> permission for the repository</p></li>
+<li><p>The target artifacts directory must exist and contain at least one file</p></li>
+<li><p>Release notes cannot be empty</p></li>
+</ul>
+<p><strong>Permissions</strong></p>
+<p>Release management requires the <code class="docutils literal notranslate"><span class="pre">release</span></code> permission, configured the same way as other repository permissions. In the config file or <code class="docutils literal notranslate"><span class="pre">.allowed</span></code> files, use <code class="docutils literal notranslate"><span class="pre">rel:target</span></code> to grant release management rights:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span># In .allowed file or config
+rel:all          # Allow everyone
+rel:9710b86...   # Allow specific identity
+rel:none         # Deny everyone
+</pre></div>
+</div>
+<p><strong>Nomad Network Interface</strong></p>
+<p>When the Nomad Network page server is enabled, releases are displayed on a dedicated releases page for each repository. Each release is listed with its tag, creation date, artifact count and a preview of the release notes. Clicking a release shows the full details including formatted release notes and a listing of all artifacts with their sizes.</p>
+<p>Only releases with <code class="docutils literal notranslate"><span class="pre">published</span></code> status are visible through the Nomad Network interface. Draft releases (if supported in future implementations) would only be visible through the command-line interface.</p>

+<p>The <code class="docutils literal notranslate"><span class="pre">rngit</span></code> utility provides full Git repository hosting and interaction over Reticulum, as well as many other useful features for software development, collaboration and publishing. It allows you to host Git repositories on Reticulum nodes, interact with remote repositories using standard Git commands through the <code class="docutils literal notranslate"><span class="pre">rns://</span></code> URL scheme, and to publish software releases.</p>
+<p>The system consists of two parts: The <code class="docutils literal notranslate"><span class="pre">rngit</span></code> node that hosts and manages repositories, and the <code class="docutils literal notranslate"><span class="pre">git-remote-rns</span></code> helper that enables Git to communicate with rngit nodes. As soon as you have RNS installed on your system, you can transparently use Git with Reticulum-hosted repositories just like any other type of remote. Git over Reticulum uses URLs in the following format: <code class="docutils literal notranslate"><span class="pre">rns://DESTINATION_HASH/group/repo</span></code>.</p>
+<p>If you set a branch to track a Reticulum remote as the default upstream, you can simply use <code class="docutils literal notranslate"><span class="pre">git</span></code> as you normally would; all commands work transparently and as expected.</p>

+<p>The <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> utility provides a fully interactive remote shell over Reticulum.
+It allows you to establish encrypted, authenticated shell sessions on remote
+systems, complete with terminal emulation, pipe support, and window resizing.</p>
+<p>While the <code class="docutils literal notranslate"><span class="pre">rnx</span></code> utility is useful for simple remote command execution and
+retrieving output, <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> provides a complete interactive terminal experience,
+making it ideal for remote administration and management tasks that require
+real-time interaction, just like SSH does for IP networks.</p>
+<p><code class="docutils literal notranslate"><span class="pre">rnsh</span></code> operates in two modes: a <em>listener</em> mode that accepts incoming
+connections, and an <em>initiator</em> mode that connects to a remote listener. Both
+sides authenticate using Reticulum Identities, ensuring that only authorised
+peers can establish sessions.</p>
+<div class="admonition note">
+<p class="admonition-title">Note</p>
+<p><code class="docutils literal notranslate"><span class="pre">rnsh</span></code> provides a genuine interactive terminal over Reticulum. It supports
+full terminal emulation including escape sequences, window resizing, signal
+forwarding, and piping of standard input, output and error streams. This
+makes it suitable for running text editors, terminal multiplexers, and any
+other interactive programs on remote systems.</p>
+</div>
+<p><strong>Usage Examples</strong></p>
+<p>Start <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> in listener mode, accepting connections from specific identities:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -a 941bed5e228775e5a8079fc38b1ccf3f -a 1b03013c25f1c2ca068a4f080b844a10
+</pre></div>
+</div>
+<p>You can also specify allowed identity hashes (one per line) in the file
+<code class="docutils literal notranslate"><span class="pre">~/.rnsh/allowed_identities</span></code> or <code class="docutils literal notranslate"><span class="pre">~/.config/rnsh/allowed_identities</span></code>, and
+simply run the program in listener mode:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l
+</pre></div>
+</div>
+<p>Connect to a remote listener from another system:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh 7a55144adf826958a9529a3bcf08b149
+</pre></div>
+</div>
+<p>Specify a command to run on the remote system, separating <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> options from
+the remote command with <code class="docutils literal notranslate"><span class="pre">--</span></code>:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh 7a55144adf826958a9529a3bcf08b149 -- top
+</pre></div>
+</div>
+<p>Set a default command for the listener, in case the initiator does not supply
+one, or when remote command execution is disabled:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -- /bin/bash --login
+</pre></div>
+</div>
+<p>Use the <code class="docutils literal notranslate"><span class="pre">-m</span></code> flag to mirror the exit code of the remote process:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -m 7a55144adf826958a9529a3bcf08b149 -- /usr/local/bin/check-status
+</pre></div>
+</div>
+<p>Use the <code class="docutils literal notranslate"><span class="pre">-p</span></code> flag to display the identity and destination hash for a listener:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -p
+
+Identity     : &lt;984b74a3f768bef236af4371e6f248cd&gt;
+Listening on : 7a55144adf826958a9529a3bcf08b149
+</pre></div>
+</div>
+<p>Use a specific identity file rather than the default:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -i /path/to/identity
+</pre></div>
+</div>
+<p>Announce the listener destination on startup, and periodically:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -b 900
+</pre></div>
+</div>
+<p>The <code class="docutils literal notranslate"><span class="pre">-b</span></code> option specifies the announce period in seconds. Use <code class="docutils literal notranslate"><span class="pre">0</span></code> to
+announce only once at startup.</p>
+<p><strong>Authentication &amp; Authorisation</strong></p>
+<p>By default, <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> requires that connecting initiators identify themselves
+with a Reticulum Identity whose hash is present in the list of allowed
+identities. Allowed identities can be specified on the command line with the
+<code class="docutils literal notranslate"><span class="pre">-a</span></code> option, and can be used multiple times:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -a 941bed5e228775e5a8079fc38b1ccf3f -a 1b03013c25f1c2ca068a4f080b844a10
+</pre></div>
+</div>
+<p>You can also maintain a list of allowed identity hashes in the file
+<code class="docutils literal notranslate"><span class="pre">~/.rnsh/allowed_identities</span></code> or <code class="docutils literal notranslate"><span class="pre">~/.config/rnsh/allowed_identities</span></code>,
+with one hex hash per line. This file is reloaded every time a new connection
+is received, so changes take effect immediately without restarting <code class="docutils literal notranslate"><span class="pre">rnsh</span></code>.</p>
+<p>If you want to accept connections from any identity (for testing or in fully
+trusted environments), you can disable authentication with the <code class="docutils literal notranslate"><span class="pre">-n</span></code> option:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -n
+</pre></div>
+</div>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Disabling authentication with <code class="docutils literal notranslate"><span class="pre">-n</span></code> means that <strong>any</strong> Reticulum peer that
+can reach your listener will be able to execute commands on your system. Only
+use this option if you <em>really</em> know what you’re doing.</p>
+</div>
+<p><strong>Remote Command Control</strong></p>
+<p>When running in listener mode, <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> allows you to control how remote
+commands are handled:</p>
+<ul class="simple">
+<li><p>By default, the listener accepts the command sent by the initiator. If the
+initiator does not supply a command, the listener’s default shell is used.</p></li>
+<li><p>Use <code class="docutils literal notranslate"><span class="pre">-C</span></code> (<code class="docutils literal notranslate"><span class="pre">--no-remote-command</span></code>) to disable execution of commands received
+from the initiator. Only the listener’s default command (or the command
+specified after <code class="docutils literal notranslate"><span class="pre">--</span></code>) will be executed:</p></li>
+</ul>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -C -- /usr/local/bin/safe-script
+</pre></div>
+</div>
+<ul class="simple">
+<li><p>Use <code class="docutils literal notranslate"><span class="pre">-A</span></code> (<code class="docutils literal notranslate"><span class="pre">--remote-command-as-args</span></code>) to append the initiator’s command
+to the listener’s default command instead of replacing it. This can be useful
+for restricting the remote to a specific program while still allowing the
+initiator to pass arguments:</p></li>
+</ul>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -A -- /usr/bin/top
+</pre></div>
+</div>
+<p><strong>Service Names</strong></p>
+<p>When running in listener mode, <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> uses a service name to differentiate
+between multiple listener instances that may share the same identity. By
+default, the service name is <code class="docutils literal notranslate"><span class="pre">default</span></code>. You can specify a different service
+name with the <code class="docutils literal notranslate"><span class="pre">-s</span></code> option:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -s monitoring
+</pre></div>
+</div>
+<p>This allows you to run multiple listeners on the same node, each with a
+different service name and purpose.</p>
+<p><strong>Initiator Options</strong></p>
+<p>When connecting to a remote listener, several options are available:</p>
+<ul class="simple">
+<li><p>Use <code class="docutils literal notranslate"><span class="pre">-N</span></code> (<code class="docutils literal notranslate"><span class="pre">--no-id</span></code>) to disable sending your identity to the remote
+listener. Note that the listener must have authentication disabled (<code class="docutils literal notranslate"><span class="pre">-n</span></code>)
+for the connection to succeed in this case.</p></li>
+<li><p>Use <code class="docutils literal notranslate"><span class="pre">-m</span></code> (<code class="docutils literal notranslate"><span class="pre">--mirror</span></code>) to make the initiator return with the exit code of
+the remote process, rather than always returning <code class="docutils literal notranslate"><span class="pre">0</span></code>.</p></li>
+<li><p>Use <code class="docutils literal notranslate"><span class="pre">-w</span></code> (<code class="docutils literal notranslate"><span class="pre">--timeout</span></code>) to specify the connection and request timeout in
+seconds. By default, the timeout matches the Reticulum path request timeout.</p></li>
+</ul>
+<p><strong>Identity &amp; Destination</strong></p>
+<p>The default identity file for <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> is stored at
+<code class="docutils literal notranslate"><span class="pre">~/.reticulum/identities/rnsh</span></code>, but you can specify a different one with the
+<code class="docutils literal notranslate"><span class="pre">-i</span></code> option, which will be created if it does not already exist:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -i /path/to/identity
+</pre></div>
+</div>
+<p>To display the identity and destination information for a listener, use the
+<code class="docutils literal notranslate"><span class="pre">-p</span></code> option. When combined with <code class="docutils literal notranslate"><span class="pre">-l</span></code>, both the identity and the listening
+destination hash are displayed:</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -p
+
+Identity     : &lt;984b74a3f768bef236af4371e6f248cd&gt;
+
+$ rnsh -l -p
+
+Identity     : &lt;984b74a3f768bef236af4371e6f248cd&gt;
+Listening on : 7a55144adf826958a9529a3bcf08b149
+</pre></div>
+</div>
+<p><strong>Verbosity</strong></p>
+<p>Like other Reticulum utilities, <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> supports the <code class="docutils literal notranslate"><span class="pre">-v</span></code> and <code class="docutils literal notranslate"><span class="pre">-q</span></code> flags
+to increase or decrease logging verbosity. Multiple flags can be specified to
+further adjust the log level. The default log level is <code class="docutils literal notranslate"><span class="pre">INFO</span></code> for listeners
+and <code class="docutils literal notranslate"><span class="pre">ERROR</span></code> for initiators.</p>
+<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>$ rnsh -l -vv       # Listener with debug-level output
+$ rnsh -q 7a55144adf826958a9529a3bcf08b149   # Quiet initiator
+</pre></div>
+</div>
+<p>By default, all log output is routed to <code class="docutils literal notranslate"><span class="pre">~/.rnsh/logfile</span></code> for initiators.</p>
+<p><strong>Escape Sequences</strong></p>
+<p>During an active <code class="docutils literal notranslate"><span class="pre">rnsh</span></code> session, the following escape sequences are
+available. These are only recognised immediately after a newline character:</p>
+<ul class="simple">
+<li><p><code class="docutils literal notranslate"><span class="pre">~~</span></code> - Send a literal tilde character</p></li>
+<li><p><code class="docutils literal notranslate"><span class="pre">~.</span></code> - Terminate the session and exit immediately</p></li>

+<li><p><code class="docutils literal notranslate"><span class="pre">~?</span></code> - Display the escape sequence quick reference</p></li>
+</ul>

+<h2>The Illusion Of The Center<a class="headerlink" href="#the-illusion-of-the-center" title="Link to this heading">¶</a></h2>
+<p>For the better part of a generation, we have been taught to visualize the digital world through the lens of hierarchy. The mental maps we carry are dominated by a single, misleading image: <strong>The Cloud</strong>.</p>
+<p>We imagine the network as a vast, ethereal space “up there” or “out there”. A centralized repository of services and data to which we, the lowly clients, must connect. We build our software with this assumption hardcoded into our logic: <em>There is a server. The server has the authority. The server knows the way. I must find the server to function</em>.</p>
+<p>This is the Client-Server mental model, and it is the primary obstacle to understanding Reticulum.</p>
+<section id="fallacy-of-the-cloud">
+<h3>Fallacy Of The Cloud<a class="headerlink" href="#fallacy-of-the-cloud" title="Link to this heading">¶</a></h3>
+<p>The first step in the Zen of Reticulum is to realize that <em>there is no cloud</em>. There is only other people’s computers. When you build for the cloud, you are building <em>for</em> a landlord. You are accepting that your application’s existence is conditional on the permission, uptime, and continued goodwill of a central authority.</p>
+<p>In Reticulum, you must shift your thinking from “connecting to” to “being among”. Reticulum is not a service you subscribe to - <em>it is a fabric you inhabit</em>. There is no “up there”. There is only <em>here</em> and <em>there</em>, and the space between them is peer-to-peer.</p>
+</section>
+<section id="decentralization-or-uncentralizability">
+<h3>Decentralization Or Uncentralizability?<a class="headerlink" href="#decentralization-or-uncentralizability" title="Link to this heading">¶</a></h3>
+<p>It is common to hear the word “decentralized” thrown around in modern tech circles. But often, this is merely a marketing term for “slightly distributed centralization”. A blockchain with a few dominant miners, or a federated protocol with a few giant servers. <em>In practice</em>, it’s still centralized. It simply has a few centers instead of one.</p>
+<p>Reticulum goes further. It wants <strong>Uncentralizability</strong>.</p>
+<p>This is not a wishful political stance, but a foundational mathematical characteristic of the protocol, onto which everything else has been built. Reticulum assumes that every peer on the network is potentially hostile, and every link is potentially compromised. It is designed with no “privileged” nodes. While some nodes may act as Transport Instances - forwarding traffic for others - they do so <em>blindly</em>, and they only know about their immediate surroundings, and nothing more. They route based on cryptographic proofs, not on administrative privilege. They cannot see who is talking to whom, nor can they selectively manipulate traffic without breaking their own ability to route entirely.</p>
+<p>The system is designed to make hierarchy structurally impossible. You cannot hijack an address, because there is no central registry to hijack. You cannot block a user, because there is no central switch to flip. You can offer paths through the network, but you can’t force anyone to use them.</p>
+</section>
+<section id="death-to-the-address">
+<h3>Death To The Address<a class="headerlink" href="#death-to-the-address" title="Link to this heading">¶</a></h3>
+<p>To break free of the center, you must also let go of the concept of the “Address”.</p>
+<p>In the IP world, an address is a location. It is a coordinate in a <em>deeply hierarchical</em> and static grid. If you move your computer to a different house, your address changes. If your router reboots, your address might change. Your <em>identity</em> is bound to your <em>location</em>, and therefore, it is fragile, and easily controlled.</p>
+<p>Reticulum abolishes this link between <em>Identity</em> and <em>Location</em>.</p>
+<p>In Reticulum, an address is not a place; it is a <strong>Hash of an Identity</strong>. It is a cryptographic representation of <em>who</em> you are, not <em>where</em> you are. Because of this, your address is portable. You can take a laptop from a WiFi cafe in Berlin, to a LoRa mesh in the mountains, to a packet radio link on a boat, and your “address” - your <em>Destination Hash</em> - never changes.</p>
+<p>The network does not route to a place; it routes to a <em>person</em> (or a machine). When you send a packet, you are not targeting a coordinate in a grid; you are encrypting a message for a specific entity. The network dynamically discovers where that entity currently resides, and it does so in a way where no one really knows where that entity is actually located physically.</p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> <em>“I am at</em> <code class="docutils literal notranslate"><span class="pre">192.168.1.5</span></code>. <em>Come find me”</em>.</p></li>
+<li><p><strong>The Zen Way:</strong> <em>“I am</em> <code class="docutils literal notranslate"><span class="pre">&lt;327c1b2f87c9353e01769b01090b18f2&gt;</span></code>. <em>Wherever I am, my peers can reach me”</em>.</p></li>
+</ul>
+<p>Once you stop thinking about servers and start thinking about portable identities, where everyone can always reach everyone else directly, the illusion of the center fades away. You realize there <em>is</em> no center holding the network together. No coordinators or bureaucrats required. The network is simply the sum of its peers, communicating directly, sovereignly, and without a master.</p>

+<h2>Physics Of Trust<a class="headerlink" href="#physics-of-trust" title="Link to this heading">¶</a></h2>
+<p><em>Paranoia Is A Great Design Principle</em></p>
+<p>If we accept that there is no center - that the network is a chaotic, peer-to-peer mesh - we are forced to confront a terrifying reality: <strong>There is no one guarding the door</strong>.</p>
+<p>In the traditional networking mindset, we rely on the concept of the “trusted core”. We assume our local coffee shop WiFi is safe, or that the backbone providers are neutral custodians. We build our security like a castle: strong walls on the outside, soft and trusting on the inside. We use encryption only when we step out into the “wild” internet.</p>
+<section id="hostile-environments">
+<h3>Hostile Environments<a class="headerlink" href="#hostile-environments" title="Link to this heading">¶</a></h3>
+<p>The Zen of Reticulum requires you to invert this. You must assume that <em>every</em> environment is hostile. This isn’t cynicism, just uncaring physics.</p>
+<p>When you transmit information over radio waves, you are shouting into a crowded room. Anyone can listen. When you traverse the internet, your packets pass through routers controlled by strangers, corporations, and state actors. Assuming privacy in this environment without cryptographic protection is not optimism but gross negligence.</p>
+<p>Reticulum is built on the premise that every link is tapped, and every peer is a potential adversary. If your system cannot survive an adversary owning the physical layer, it cannot survive at all.</p>
+<p>But this is the paradox: By assuming the network is hostile, you make it safe. When you accept the dangers for what they are, they become manageable. When you stop trusting the infrastructure and start trusting the math, you eliminate the single point of failure: Human integrity.</p>
+</section>
+<section id="encryption-is-not-a-feature">
+<h3>Encryption Is Not A Feature<a class="headerlink" href="#encryption-is-not-a-feature" title="Link to this heading">¶</a></h3>
+<p>In the world of TCP/IP, encryption is an afterthought. It is a layer we slap on top of the protocol (HTTPS, TLS) to patch the security holes of the original design. It is a “feature” you sometimes <em>enable</em> for “sensitive data”. This is fundamentally flawed, since all data is sensitive.</p>
+<p>In Reticulum, encryption is <strong>gravity</strong>.</p>
+<p>It is not optional. It is not a plugin. It is the <em>fundamental force that allows the network to exist</em>. If you were to strip the encryption from Reticulum, the routing would break. The Transport system uses cryptographic signatures and entropy to verify paths and pass information. If packets were plaintext, intermediate nodes could not prove that a route was valid, nor could endpoints prevent spoofing or tampering.</p>
+<p>In Reticulum, the entropy of the encrypted packet <em>is</em> the routing logic.</p>
+<p>To ask for a version of Reticulum without encryption is like asking for a version of the ocean without liquid. You are not asking for a feature change; you’re asking for a different physical universe. We design for a universe where information has mass, structure, and integrity.</p>

+<section id="zero-trust-architectures">
+<h3>Zero-Trust Architectures<a class="headerlink" href="#zero-trust-architectures" title="Link to this heading">¶</a></h3>
+<p>We must unlearn our reliance on <strong>Institutional Trust</strong>.</p>
+<p>For decades, we have been trained to trust authorities. We trust a website because a chain of Certificate Authorities (companies we don’t know) vouches for it. We trust an app because it is in an app store (run by a corporation we don’t control). We trust a message because it comes from a phone number assigned by a telecom. Yet, everything in our digital information sphere today is more untrustworthy and risky than a medieval second-hand underwear market.</p>
+<p>Reticulum replaces institutional trust with <strong>Cryptographic Proof</strong>.</p>
+<p>In Reticulum, you do not trust a node because it has a nice hostname or because it is listed in a directory. You trust it because it holds the private key corresponding to the Destination Hash you are communicating with. This trust is binary, mathematical, and <strong>absolute</strong>. Either the signature matches, or it does not. There is no “maybe”.</p>
+<p>This shift moves the power from the institution to the individual. You become the ultimate arbiter of your own trust relationships. You decide which keys to accept, which paths to follow, and which identities to recognize.</p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> <em>“I trust this site because the browser says the lock icon is green”</em>.</p></li>
+<li><p><strong>The Zen Way:</strong> <em>“I trust this destination because I have verified its hash fingerprint out-of-band, and the math confirms the signature”</em>.</p></li>
+</ul>
+<p>When you internalize the Physics of Trust, you stop looking for protection from firewalls, VPNs, and Terms of Service agreements. You realize that true security comes from the design of the protocol itself. You can stop trusting the cloud, and you start trusting the code - because you can verify it yourself.</p>

+<h2>Merits Of Scarcity<a class="headerlink" href="#merits-of-scarcity" title="Link to this heading">¶</a></h2>
+<p><em>Every Bit Counts</em></p>
+<p>We have grown addicted to abundance. In the modern digital ecosystem, bandwidth is treated as an endless, flat ocean. We stream high-definition video without a thought, we ship entire libraries of code just to render a single button, and we measure performance in gigabits per second. This abundance has hollowed out our craft. When constraints vanish, efficiency dies, and with it, a certain kind of Clarity and Quality.</p>
+<p>Reticulum asks you to step out of the ocean and onto the tightrope.</p>
+<section id="the-bandwidth-fallacy">
+<h3>The Bandwidth Fallacy<a class="headerlink" href="#the-bandwidth-fallacy" title="Link to this heading">¶</a></h3>
+<p>The Zen of Reticulum requires the realization that <strong>5 bits per second is a valid speed</strong>.</p>
+<p>To a modern developer, this sounds like paralysis. But there is a profound freedom in limits: When you have a gigabit connection, you can be incredibly sloppy. You can be wasteful. You can push your problems onto the infrastructure. <em>“It’s slow? Get a faster router”</em>.</p>
+<p>But on a high-latency, low-bandwidth link (be it a noisy HF radio channel or a tenuous LoRa hop) you cannot push problems anywhere. You must solve them. The network does not negotiate with waste.</p>
+<p>This forces a shift from consumption to interaction. You are no longer, then, consuming a service provided by a fat pipe; you are engaging in a careful negotiation with the physical medium. The medium becomes a partner in the conversation, not just a dumb conduit. You suddenly need to <em>understand the world to be in it</em>.</p>
+</section>
+<section id="cost-of-a-byte">
+<h3>Cost Of A Byte<a class="headerlink" href="#cost-of-a-byte" title="Link to this heading">¶</a></h3>
+<p>In a scarce economy, a byte is not just data, but energy, time, and space.</p>
+<p>Every byte you transmit consumes battery life on a solar-powered node. It occupies valuable airtime that could have been used by another peer. It represents a measurable slice of the electromagnetic spectrum.</p>
+<p>When you internalize this, you begin to write code differently. You stop asking, “How much data can I send?” and start asking, “What is the <em>minimum</em> amount of information required to convey this intent? How can I best utilize my informational entropy?”</p>
+<p>This is where the elegance of Reticulum shines. The protocol is designed to strip away the non-essential. A link establishment takes three very small packets. A destination hash fits in 16 bytes. The overhead is vanishingly small, leaving almost the entire channel for the message itself.</p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> <em>“I need to send a status update. I’ll send a JSON object with metadata, timestamps, and user profile info (15KB).”</em></p></li>
+<li><p><strong>The Zen Way:</strong> <em>“I need to send a status update. I’ll send a single byte representing the state code. The context is already known.”</em></p></li>
+</ul>
+<p>This is of course optimization, but more importantly, <em>it is a form of respect</em>. Efficiency in a shared medium is an act of stewardship. By taking only what you need from the network, you leave room for others. The network listens to those who speak with purpose.</p>
+</section>
+<section id="flow-time">
+<h3>Flow &amp; Time<a class="headerlink" href="#flow-time" title="Link to this heading">¶</a></h3>
+<p>Scarcity also teaches us about time. We have become addicted to the <em>synchronous</em> now - the instant ping, the real-time stream. But Reticulum embraces <em>asynchronous</em> time.</p>
+<p>When links are intermittent and latency is measured in minutes or hours, “real-time” is an illusion. Reticulum doesn’t encourage <strong>Store and Forward</strong> as a mere fallback, but as a primary mode of existence. You write a message, it propagates when it can, and it arrives when it arrives.</p>
+<p>This changes the psychological texture of communication. It removes the anxiety of the immediate response. It allows for contemplation. You are not demanding the recipient’s attention <em>right now</em>; you are placing a gift in their path, to be found when they are ready.</p>
+<p>By designing for delay, you design for resilience. You are no longer building a house of cards that collapses when a single packet drops. You are building a stone arch that distributes the load <em>over time</em>.</p>
+</section>
+<section id="liberation-from-limits">
+<h3>Liberation From Limits<a class="headerlink" href="#liberation-from-limits" title="Link to this heading">¶</a></h3>
+<p>There is a strange optimism in scarcity. When you are forced to work within strict constraints, you are forced to prioritize. <em>You</em> must decide what truly matters. <em>That</em> is the real core of agency.</p>
+<p>In the infinite fantasy world of The Cloud, everything is urgent, so nothing is. In the economy of Reticulum, the cost of transmission forces you to weigh the value of your message. Do you really need to send that heart beat? Is that photo essential?</p>
+<p>When you strip away the noise, what remains is <em>signal</em>.</p>
+<p>This discipline creates a different kind of developer. It creates a craftsman who understands that the best code is the code you don’t have to write. It creates a user who understands that the most powerful message is the one that is <em>understood</em>, not the one that is loudest. In the world of Reticulum, you are not a mere consumer of bandwidth; you are an architect of intent.</p>

+<h2>Sovereignty Through Infrastructure<a class="headerlink" href="#sovereignty-through-infrastructure" title="Link to this heading">¶</a></h2>
+<p><strong>Be Your Own Network</strong></p>
+<p>We live in an era of digital tenancy. We lease our connectivity from ISPs. We rent our storage from cloud providers. We even borrow our identity from social media platforms. We are tenants in a house we did not build, governed by rules we did not write, subject to eviction at the whim of a landlord who has never met us.</p>
+<p>The Zen of Reticulum is the realization that you <em>can</em> own the house.</p>
+<section id="a-carrier-grade-fallacy">
+<h3>A Carrier-Grade Fallacy<a class="headerlink" href="#a-carrier-grade-fallacy" title="Link to this heading">¶</a></h3>
+<p>For decades, we have been gaslit into believing that networking is really not just hard, but impossible. It is presented as a dark art reserved for telcos and billionaires, requiring millions of dollars of fiber optics, climate-controlled data centers, and armies of engineers. We are told that building reliable infrastructure is “too complex” for the individual or small organization.</p>
+<p>This is a big, fat lie.</p>
+<p>Physics is simple. A radio wave needs a transmitter and a receiver. A packet needs a path. The “complexity” of the modern internet is largely bureaucratic - a mountain of billing systems, regulatory capture, and legacy cruft designed to keep the gatekeepers in power.</p>
+<p>Reticulum strips away the bureaucracy. It runs on hardware that costs the price of a dinner. It runs on spectrum that is free to use. It demonstrates that a robust, planetary-scale network does not require a Fortune 500 company. It requires only the will to deploy, and the distributed, uncoordinated efforts of many individuals.</p>
+</section>
+<section id="personal-infrastructure">
+<h3>Personal Infrastructure<a class="headerlink" href="#personal-infrastructure" title="Link to this heading">¶</a></h3>
+<p>This is where the rubber meets the road. You can read about Reticulum, you can understand the theory, but the insights only arrive when you plug in a radio and run a Transport Node. Suddenly, you are no longer a consumer. You’re an operator.</p>
+<p>This shift is subtle but profound. When you run your own infrastructure, the network ceases to be a service that is provided <em>to</em> you. It becomes a space that you <em>inhabit</em>. You become responsible for the flow of information. You gain an intimate understanding of the medium - the way the weather affects the radio waves, the way the topology changes, the way the packets dance through the ether.</p>
+<p>There is a quiet competence that comes from this. You stop asking “Is the internet down?” and start asking “Is <em>my</em> links up?” You stop waiting for a technician and start checking the logs. This is a form of strength. To understand the system that carries your words is to be free from the mystery that keeps you dependent.</p>

+<p>Why go to the trouble? Why buy the radio, write the config, and leave the Pi running in the corner?</p>
+<p>Because the old, centralized network is fragile. And because most of us doesn’t even really want to be there anymore.</p>
+<p>The internet we rely on today is a chain of single points of failure. Cut the undersea cable, and a continent goes dark. Shut down the power grid, and the cloud evaporates. Deprioritize the “wrong” traffic, and the flow of information is strangled.</p>
+<p>Sovereignty is the ability to survive the cut, whether or not that cut was an accident or on purpose.</p>
+<p>When you build your own infrastructure, you build a lifeline. Reticulum is designed to function over media that the traditional internet cannot touch - bare wires, battery-powered radios, ad-hoc WiFi meshes. When the grid fails, or the censors arrive, or the bill goes unpaid, your Reticulum network continues to hum.</p>
+<p>This is not about “dropping out” of society. It is about building a substrate on which an actual <em>Society</em> can function.</p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> “My connection is slow. I should call my ISP and complain.”</p></li>
+<li><p><strong>The Zen Way:</strong> “The path is noisy. I will adjust the antenna or find a better route.”</p></li>
+</ul>
+<p>By taking ownership of the infrastructure, you take ownership of your voice. You stop shouting into someone else’s megaphone and start building your own. The network is no longer something that happens to you; it is something you make happen.</p>

+<p>In Reticulum, your identity is not a location, or a username granted by a service. It is a cryptographic key - a complex, unique mathematical signature that exists independently of the physical world. You can carry it only in your mind, if you want to.</p>
+<p>Think of it less like a street address and more like a name. <em>A true name</em>.</p>
+<p>If you travel from Berlin to Tokyo, you do not change your name. You are still you. The people who know you can still recognize you. Reticulum applies this principle to the network layer. Your Destination Hash is <strong>invariant</strong>. It travels with you, stored securely on your device, <em>immutable as a stone</em>.</p>
+<p>This changes the relationship between you and the machine. You are not “logged into” the network via a specific gateway. You <em>are</em> the endpoint. The network does not connect to a place; <em>it converges on you</em>.</p>

+<h3>Roaming Nodes<a class="headerlink" href="#roaming-nodes" title="Link to this heading">¶</a></h3>
+<p>This freedom introduces a new concept of time and space: <strong>Nomadism</strong>.</p>
+<p>Because your identity is portable, your connectivity can be fluid. You can be sitting at a desk connected to a fiber backbone one moment, and walking through a field connected only to a long-range LoRa mesh the next. To the rest of the network, nothing has changed. Your friends do not need to update your contact info. The messages they send do not bounce back. The network senses the shift in the medium and reroutes the flow of data automatically.</p>
+<p>You are no longer a stationary node in a fixed grid. You are a wanderer in a fluid medium.</p>
+<p>The interfaces - whether it is WiFi, Ethernet, Packet Radio, or a physical wire - is merely the clothing your node wears. You change it to suit the environment. Underneath, you remain the same. This is the liberation of the protocol. It treats the physical medium as a transient circumstance, not a definition of self.</p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> <em>“I lost connection. I have to reconnect to the VPN to tell them where I am now.”</em></p></li>
+<li><p><strong>The Zen Way:</strong> <em>“I moved. The network subtly bends to accomodate this new reality.”</em></p></li>

+<section id="announcing-presence">
+<h3>Announcing Presence<a class="headerlink" href="#announcing-presence" title="Link to this heading">¶</a></h3>
+<p>How does the network find a wanderer? It listens.</p>
+<p>In the IP world, we query directories. We ask a server, “Where is Mark?” The server checks its database and gives us a coordinate. This means that someone, somewhere, is keeping track of you. It assumes and <em>requires</em> surveillance.</p>
+<p>Reticulum replaces surveillance with <strong>Announces</strong>.</p>
+<p>Instead of asking a central authority where you are, you simply state your presence. You broadcast a cryptographic proof: “I am here, and I am who I say I am”. This ripples out through the mesh. Your neighbors hear it, update their path tables, and pass it on.</p>
+<p>This is a quiet, organic process. It is the digital equivalent of lighting lanterns in the dark. You do not need to chase the light; you let the light find you. It respects your autonomy. You choose when to announce, how often to speak, and to whom. You also choose when to disappear - for but a moment or perpetually.</p>

+<h3>Anchor In The Flow<a class="headerlink" href="#anchor-in-the-flow" title="Link to this heading">¶</a></h3>
+<p>There is a deep peace in this nomadism. It teaches you that stability does not come from standing still. Stability comes from <em>internal coherence</em>.</p>
+<p>By holding your own private key, you hold your own center of gravity. The world around you; the infrastructure, the topography and the availability of links can all shift chaotically. Storms can knock out towers. Cables can be cut. The internet can go down.</p>
+<p>But as long as you possess your key, you possess your identity. The entire infrastructure can be destroyed and rebuilt, and you are still you. Nothing lasts, yet nothing is lost.</p>
+<p>You become a sovereign entity moving through the noise, connected not by the rigidity of cables, but by the fluidity of recognition. The network becomes a place you inhabit, rather than a utility you subscribe to: You are at home in the ether.</p>

+<h2>Ethics Of The Tool<a class="headerlink" href="#ethics-of-the-tool" title="Link to this heading">¶</a></h2>
+<p><strong>Technology With Conscience</strong></p>
+<p>You have unlearned the center. You have accepted the physics of trust. You have embraced the economy of scarcity and the freedom of unbound nomadism. You are standing in a new space. Now, look at the tool in your hand.</p>
+<p>In the old world, we were taught that technology is neutral. We are told that “guns don’t kill people, people do”, or that a component is just a component, indifferent to what its combinatorial potential is. This is a convenient lie. It serves only to allow the builders to wash their hands of responsibility.</p>
+<p>But we know better now. We know that <strong>architecture is politics</strong>, and <em>politics is control</em>. The way you build a system determines how it will be used. If you build a system optimized for mass surveillance, you <em>will</em> get a panopticon. If you build a system optimized for centralized control, you <em>will</em> get a dictatorship. If you build a system optimized for extraction, you <em>will</em> get a parasite.</p>
+<p>The Zen of Reticulum asserts that a tool is never neutral.</p>
+<p>On the very contrary: A tool is intent, <strong>crystallized</strong>.</p>
+<section id="the-harm-principle">
+<h3>The Harm Principle<a class="headerlink" href="#the-harm-principle" title="Link to this heading">¶</a></h3>
+<p>Why does the Reticulum License forbid the software from being used in systems designed to harm humans? Is it not just a restriction on freedom?</p>
+<p>It is a restriction on <em>license</em>, yes, but it is an expansion of <em>freedom</em>.</p>
+<p>Building powerful tools without a moral compass is in no way virtuous or commendable, it is plain and simple irresponsibility.</p>
+<p>A tool that can easily be used to oppress is a real danger to the user. If you build a network that can be turned against you by a tyrant, you are not free. You are merely waiting for the leash to tighten. By encoding the “Harm Principle” into the legal DNA of the reference implementation, we are building a safeguard. We are stating, clearly and immutably, that <em>this tool</em> is for <strong>life</strong>, not for death.</p>
+<p>This aligns the software with the interests of humanity. It cements that the network cannot be conscripted into a kill-system, a weaponized drone controller, or a torture device without breaking the license and the law. It is a line drawn in the sand - not by a government or external authority, but by the creators of the tool itself.</p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> <em>“It’s just software. How people use it is not my problem.”</em></p></li>
+<li><p><strong>The Zen Way:</strong> <em>“This software is a habitat. I will not allow it to be used to build a cage.”</em></p></li>
+</ul>
+<p>It is <em>your</em> choice whether to align with this - we are not forcing this stance on anyone. If you choose to align with life over death, with creativity over destruction, we grant you an immensely powerful tool, to own and build with as you please. If you do not, we deny it.</p>
+<p>If you do not like this, we most assuredly do not need you here, and you are on your own.</p>

+<section id="public-domain-protocol">
+<h3>Public Domain Protocol<a class="headerlink" href="#public-domain-protocol" title="Link to this heading">¶</a></h3>
+<p>This leads to a vital distinction: The difference between the <em>idea</em> and the <em>implementation</em>.</p>
+<p>The protocol - the mathematical rules of how Reticulum works - is dedicated to the Public Domain. It belongs to humanity. <strong>No one can own it</strong>. Anyone can implement it, improve it, or adapt it. This is the core idea of free communication, which itself must be forever free.</p>
+<p>But the functional, deployed <em>reference implementation</em> - the Python code, the maintenance, the years of labor - has a conscience. This distinction is the engine of sustainability. It allows the protocol to be universal, while ensuring that the specific labor of the builders is not hijacked to undermine the foundational intent of the project itself. From this document, it should be very clear what this intent is.</p>
+<p>If you want to build a system with Reticulum that manipulates and damages users for profits or targets missiles, you can use the public domain protocol, and start from scratch. But you cannot take our work. You must do your own. This serves as a pillar of accountability. If you want to build a weapon, <em>you</em> go and forge the steel yourself, while the world observes. And when the blood is drawn - it is on <strong>your</strong> hands.</p>

+<h3>Preserving Human Agency<a class="headerlink" href="#preserving-human-agency" title="Link to this heading">¶</a></h3>
+<p>We live in an era of predatory extraction. The open-source commons is being scraped, ingested, and regurgitated by machine learning algorithms, whose corporate owners seek to replace the very humans who built those commons. Our code, our words, and our creativity is being used to train systems that are specifically designed to make us obsolete, without offering anything else in return than serfdom and leashes.</p>
+<p>Reticulum stands against this.</p>
+<p>The license protects the software from being used to feed the beast. It draws a hard line: This tool is for <em>people</em>. It is for human-to-human connection. It is not a dataset to be strip-mined for the purpose of building a synthetic overlord, puppeteered by a miniscule conglomerate of controllers.</p>
+<p>This is a radical act of preservation. By protecting the code from AI appropriation, we are protecting space for human agency. We are ensuring that there remains a digital realm where the actors are flesh, blood and soul, where decisions are made by minds, not overlords hiding behind models.</p>
+<p>When you use Reticulum, you are using a tool that respects you. It does not see you as a product to be tracked. It does not see your data as fuel for an algorithm. It sees you as a sovereign, equal peer.</p>
+<p>This changes the foundational premise of using the technology. It restores dignity to the interaction. You are not the user of a service; you are a participant in a mutual covenant. The tool aligns with your autonomy, rather than eroding it.</p>
+<p>In this way, ethics is not a restriction, but a foundation. It is the foundation that helps ensure the network will still belong to you tomorrow.</p>

+<h2>Design Patterns For Post-IP Systems<a class="headerlink" href="#design-patterns-for-post-ip-systems" title="Link to this heading">¶</a></h2>
+<p><strong>Practical Philosophy for Developers</strong></p>
+<p>The philosophy is useless if it cannot be hammered into code. The metaphors we have explored - nomadism, scarcity, trust - are not just poetry, but real-world engineering constraints. When you sit down to write software for Reticulum, these concepts must shape the very structure of your application.</p>
+<p>We are now moving from the <em>why</em> to the <em>how</em>. This is where the abstract becomes concrete, and where you will see the true depth of the patterns we have been weaving.</p>
+<section id="store-forward">
+<h3>Store &amp; Forward<a class="headerlink" href="#store-forward" title="Link to this heading">¶</a></h3>
+<p>The web has trained us to be impatient. We write synchronous code. We fire a request and we wait, blocking the UI, holding our breath. If the response doesn’t come in 250 milliseconds, we show a spinner. If it doesn’t come in five seconds, we show an error. We treat network connectivity as a binary state: either we are “online” or we are “broken”.</p>
+<p>This is brittle. It is a rejection of reality.</p>
+<p>In Reticulum, connectivity is a spectrum, and presence is asynchronous. If at all applicable to your intent, you must design your applications to embrace <strong>Store &amp; Forward</strong>.</p>
+<p>Instead of demanding an immediate answer, your application should act as a patient participant. You create a message for someone or something in the mesh. The network holds it. It carries it from node to node, perhaps over hours or days, waiting for the recipient to appear. When they finally surface, the message is delivered. This requires a shift from “request/response” to “event/handler”. How exactly you do this is a challenge for you to solve intelligently within your problem domain, but Reticulum-based systems already exist that does this extremely well, and you can use them for inspiration.</p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> <code class="docutils literal notranslate"><span class="pre">Connect()</span> <span class="pre">-&gt;</span> <span class="pre">Send()</span> <span class="pre">-&gt;</span> <span class="pre">Wait()</span> <span class="pre">-&gt;</span> <span class="pre">Crash</span> <span class="pre">if</span> <span class="pre">timeout.</span></code></p></li>
+<li><p><strong>The Zen Way:</strong> <code class="docutils literal notranslate"><span class="pre">Send()</span> <span class="pre">-&gt;</span> <span class="pre">Continue</span> <span class="pre">living.</span> <span class="pre">-&gt;</span> <span class="pre">Receive()</span> <span class="pre">when</span> <span class="pre">it</span> <span class="pre">arrives.</span></code></p></li>
+</ul>
+<p>This changes the user experience profoundly. It removes the anxiety of the loading bar. It creates a sense of continuity. The user is not “waiting for the network”; they are interacting with a persistent log of communication that lives in the network itself.</p>
+</section>
+<section id="naming-is-power">
+<h3>Naming Is Power<a class="headerlink" href="#naming-is-power" title="Link to this heading">¶</a></h3>
+<p>In the IP world, we are slaves to the Domain Name System. We rely on a hierarchy of registrars to map human-readable names to machine-readable addresses. This hierarchy is a choke point. If the registrar revokes your domain, or if the DNS server goes down, you vanish.</p>
+<p>Reticulum dissolves this hierarchy with <strong>Hash-based Identity</strong>.</p>
+<p>In this design pattern, a name is not a string you look up; it is a cryptographic destination you verify. When you design for Reticulum, you stop asking the user for a URL and start asking for a Destination or Identity Hash.</p>
+<p>This feels strange at first. A hash like <code class="docutils literal notranslate"><span class="pre">&lt;83b7328926fed0d2e6a10a7671f9e237&gt;</span></code> looks alien compared to <code class="docutils literal notranslate"><span class="pre">myfriend.com</span></code>. But that alienness is the armor. It <strong>cannot</strong> be spoofed. It <strong>cannot</strong> be censored by a registrar. It is <strong>absolute</strong>.</p>
+<p>Designing for this means shifting your UI metaphors. You are no longer browsing a web of pages; you are managing a ledger of keys. You are building an “Address Book” that is actually a keyring. The names are given by the user, and the power stays with them. That hashes look complex is directly analogous to the strengths of the bonds formed by their use. It forces the user to engage in a moment of verification, an out-of-band handshake, which restores the human element of trust that SSL certificates stripped away.</p>

+<section id="the-interface-is-the-medium">
+<h3>The Interface Is The Medium<a class="headerlink" href="#the-interface-is-the-medium" title="Link to this heading">¶</a></h3>
+<p>One of the most liberating patterns in Reticulum is <strong>Transport Agnosticism</strong>.</p>
+<p>In traditional networking, your code is often littered with transport logic. “Am I on WiFi? Check bandwidth. Am I on Cellular? Check data plan. Am I on Ethernet?”. You are constantly micromanaging the pipe.</p>
+<p>In Reticulum, you write to the API, and the API writes to the medium. You send a packet to a Destination. You do not care if that packet travels over a TCP tunnel, a LoRa radio wave, or a serial wire interface. That is the stack’s concern.</p>
+<p>This allows you to write <strong>Universal Applications</strong>.
+Imagine a messaging app. You write it once. It works on a laptop connected to fiber. It works on a phone in the city using WiFi. And, without a single line of code changed, it works on a device in the wilderness, talking only to other devices via radio.</p>
+<p>The pattern is simple: <strong>Never code to the hardware. Code to the intent.</strong></p>
+<p><strong>Consider:</strong></p>
+<ul class="simple">
+<li><p><strong>The Old Way:</strong> <code class="docutils literal notranslate"><span class="pre">socket.connect(ip,</span> <span class="pre">port)</span></code>, and then a whole lot more</p></li>
+<li><p><strong>The Zen Way:</strong> <code class="docutils literal notranslate"><span class="pre">RNS.Packet(destination,</span> <span class="pre">data).send()</span></code></p></li>
+</ul>
+<p>By abstracting the medium, you make your software immortal to changes in infrastructure. The user might switch from a 4G hotspot to a HF modem tomorrow. Your software doesn’t need to know. It simply continues the conversation.</p>
+</section>
+<section id="emergent-patterns">
+<h3>Emergent Patterns<a class="headerlink" href="#emergent-patterns" title="Link to this heading">¶</a></h3>
+<p>When you combine these patterns - <em>Store &amp; Forward</em>, <em>Hash-based Identity</em>, and <em>Transport Agnosticism</em> - you create software that feels fundamentally different.</p>
+<p>It feels <em>grounded</em>. It doesn’t flicker when the signal drops. It doesn’t panic when the server is down. It has weight. It has persistence. It has <em>relevance</em>.</p>
+<p>You are no longer building a “client” that begs a “server” for attention. You are building an autonomous agent that exists within the mesh. It speaks when it needs to, listens when it can, and carries its identity with it wherever it goes.</p>
+<p>This is the culmination of the Zen. The code is not just a set of instructions: It is a behavioral envelope. It is a way of <em>being</em> in the network.</p>

+<p>This is a reclaiming of the commons. For too long, we have allowed the most vital substrate of human society - <em>our ability to speak to one another</em> - to be colonized by entities that do not share our interests. We have allowed the architecture of our communication to be designed by accountants rather than architects.</p>
+<p>We are taking it back. Not by petitioning the masters, but by building the new world within, over, under and around the shell of the old.</p>

+<p>The heavy lifting is done.</p>
+<p>The protocol is in the public domain, a gift to humanity that can never be taken away. The software is written, tested, and running on devices scattered across the globe. The manual lies open before you. The source code for the reference implementation is now distributed on hundreds of thousands of devices across the planet. No one can delete or destroy it. The hardware is accessible and abundant.</p>
+<p>It was a hard road to get here, but we got here. Now, there is no roadmap committee waiting for approval. There is no venture capital dictating the user experience. There is no CEO to sign off on the next feature release.</p>
+<p>There is only you.</p>
+<p>The barrier to entry is no longer complexity: It is the mere habit of dependency. You were conditioned to wait. Wait for the app update. Wait for the ISP to fix the line. Wait for the platform to allow the post. Wait for the government to change the policies. Wait for the likes. Wait for the revolution to be televised.</p>

+************************
+Using Git Over Reticulum
+************************
+
+A set of utilities for distributed collaborative software development and publishing is included in RNS.
+
+The system consists of two parts: The ``rngit`` node that hosts repositories, and the ``git-remote-rns`` helper that enables Git to communicate with rngit nodes. As soon as you have RNS installed on your system, you can transparently use Git with Reticulum-hosted repositories just like any other type of remote. Git over Reticulum uses URLs in the following format: ``rns://DESTINATION_HASH/group/repo``.
+
+If you set a branch to track a Reticulum remote as the default upstream, you can simply use ``git`` as you normally would; all commands work transparently and as expected.
+
+.. warning::
+   **The rngit program is a new addition to RNS!** This functionality was introduced in RNS 1.2.0. While great care has been taken to design a secure, but highly configurable and flexible permission system for allowing many users to interact with many different repositories on a single node, ``rngit`` has not been tested extensively in the wild! Be careful when hosting repositories, especially if they are public or semi-public.
+
+The rngit Utility
+=================
+
+The ``rngit`` utility provides full Git repository hosting and interaction over Reticulum. It allows you to host and manage Git repositories and releases on Reticulum nodes, and to interact with remote repositories using standard Git commands through the ``rns://`` URL scheme.
+
+**Usage Examples**
+
+Run ``rngit`` to start a repository node:
+
+.. code:: text
+
+  $ rngit
+
+  [Notice] Starting Reticulum Git Node...
+  [Notice] Reticulum Git Node listening on <0d7334d411d00120cbad24edf355fdd2>
+
+On the first run, ``rngit`` will create a default configuration file. You will then need to edit this, to point to your repository locations, configure access permissions, and perform any other necessary configuration.
+
+View your identity and destination hashes:
+
+.. code:: text
+
+  $ rngit --print-identity
+
+  Git Peer Identity         : <959e10e5efc1bd9d97a4083babe51dea>
+  Repository Node Identity  : <153cb870b4665b8c1c348896292b0bad>
+  Repositories Destination  : <0d7334d411d00120cbad24edf355fdd2>
+
+If the page server is enabled, the output will also include the Nomad Network destination hash.
+
+You can run ``rngit`` in service mode with logging to file:
+
+.. code:: text
+
+  $ rngit -s
+
+Clone a repository from a remote ``rngit`` node:
+
+.. code:: text
+
+  $ git clone rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo
+
+Add a Reticulum remote to an existing repository:
+
+.. code:: text
+
+  $ git remote add some_remote rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo
+
+Push changes to the Reticulum remote:
+
+.. code:: text
+
+  $ git push some_remote master
+
+Get changes from a remote repository:
+
+.. code:: text
+
+  $ git pull rns_remote master
+
+**All Command-Line Options (rngit)**
+
+.. code:: text
+
+  usage: rngit.py [-h] [--config CONFIG] [--rnsconfig RNSCONFIG] [-s] [-i] [-v]
+                  [-q] [--version]
+
+  Reticulum Git Repository Node
+
+  options:
+    -h, --help            show this help message and exit
+    --config CONFIG       path to alternative config directory
+    --rnsconfig RNSCONFIG
+                          path to alternative Reticulum config directory
+    -p, --print-identity  print identity and destination info and exit
+    -s, --service         rngit is running as a service and should log to file
+    -i, --interactive     drop into interactive shell after initialisation
+    -v, --verbose         increase verbosity
+    -q, --quiet           decrease verbosity
+    --version             show program's version number and exit
+
+**All Command-Line Options (git-remote-rns)**
+
+The ``git-remote-rns`` helper is automatically invoked by Git when interacting with ``rns://`` URLs. It is not typically run directly by users, but accepts the following environment variables for configuration:
+
+- ``RNGIT_CONFIG`` - Path to alternative client configuration directory
+- ``RNS_CONFIG`` - Path to alternative Reticulum configuration directory
+
+The client configuration file is located at ``~/.rngit/client_config`` and allows adjusting parameters such as the reference batch size for transfers.
+
+
+Repository Structure
+====================
+
+The ``rngit`` node organizes repositories into groups. Each group is a directory containing bare Git repositories. The repository path format is ``group_name/repo_name``. For example, a repository at ``/var/git/public/myrepo`` would be accessible as ``public/myrepo`` via the URL ``rns://DESTINATION_HASH/public/myrepo``.
+
+**Configuration**
+
+The ``rngit`` node configuration file is located at ``~/.rngit/config`` (or ``/etc/rngit/config`` for system-wide installations). The default configuration includes:
+
+- Repository group paths defining where to find bare repositories
+- Access permissions for groups and individual repositories
+- Announce intervals for network visibility
+- Optional statistics recording for repository activity
+
+Access permissions can be configured at the group level in the config file, or per-repository using ``.allowed`` files. Permissions use the format ``permission:target`` where permission is ``r`` (read), ``w`` (write), ``rw`` (read/write), ``c`` (create) or ``s`` (stats) and target is ``all``, ``none``, or a specific identity hash.
+
+The ``s`` (stats) permission allows viewing repository activity statistics, including views, fetches and pushes over time. To enable statistics recording, set ``record_stats = yes`` in the ``[rngit]`` section of the configuration file. You can also exclude specific identities from statistics by adding their hashes to ``stats_ignore_identities``.
+
+Repository-specific ``.allowed`` files can be static text files or executable scripts that output permission rules to stdout. A ``group.allowed`` file in a repository group directory applies to all repositories within that group.
+
+Serving Pages Over Nomad Network
+================================
+
+In addition to providing Git repository access via the Git remote helper protocol, ``rngit`` can also run a `Nomad Network <https://github.com/markqvist/nomadnet>`_ compatible page node. This allows users to browse repository information, view file contents, inspect commit history and access repository statistics through any Nomad Network client.
+
+When enabled, the page node provides a complete interface to your repositories, with automatic Markdown to Micron conversion, syntax-highlighted code browsing, and detailed commit, diff and statistics views.
+
+**Enabling the Git Page Node**
+
+To enable the page node, add the following to your ``~/.rngit/config`` file:
+
+.. code:: text
+
+  [pages]
+  serve_nomadnet = yes
+
+When the page node is enabled, ``rngit`` will listen on a Nomad Network node destination in addition to the Git repository destination. You can view the destination hash by running:
+
+.. code:: text
+
+  $ rngit --print-identity
+
+  Git Peer Identity         : <959e10e5efc1bd9d97a4083babe51dea>
+  Repository Node Identity  : <153cb870b4665b8c1c348896292b0bad>
+  Repositories Destination  : <0d7334d411d00120cbad24edf355fdd2>
+  Nomad Network Destination : <50824b711717f97c2fb1166ceddd5ea9>
+
+**Accessing Repository Pages**
+
+Once the page server is running, you can access it from any Nomad Network client by connecting to the Nomad Network destination. The page node provides the following views:
+
+- **Front Page** - Lists all repository groups accessible to your identity
+- **Group Page** - Shows all repositories within a group
+- **Repository Page** - Displays repository overview, description and README
+- **Releases** - List of releases for the repository, with information and downloads
+- **File Browser** - Browse directory trees and view and download file contents
+- **Commits View** - View commit history with pagination
+- **Commit Details** - Detailed commit information with file changes and diffs
+- **Refs View** - List branches and tags
+- **Statistics** - Activity charts showing views, fetches and pushes over time
+
+All pages respect the same permission system used for Git access. If an identity does not have read access to a repository, they will not be able to view its pages.
+
+Formatting & Syntax Highlighting
+================================
+
+If the ``pygments`` Python module is installed on your system, the page server will automatically apply syntax highlighting to code files. The highlighting supports a wide range of programming languages and uses a color theme optimized for terminal display.
+
+To enable syntax highlighting, install pygments:
+
+.. code:: text
+
+  pip install pygments
+
+**Markdown & Micron Support**
+
+README files and other Markdown documents are automatically converted to Micron markup for display in Nomad Network clients. You can also write your README files directly in Micron, in which case they will display and render as such in any Nomad Network client. The file browser also supports viewing both rendered and raw Markdown and Micron documents.
+
+Code blocks in Markdown can include language hints for syntax highlighting:
+
+.. code:: text
+
+  ```python
+  def hello_world():
+      print("Hello, Reticulum!")
+  ```
+
+Customizing Templates
+=====================
+
+The page server uses a template system that allows complete customization of the generated pages. Templates are stored in the ``~/.rngit/templates/`` directory as Micron files.
+
+The following template files are supported:
+
+- ``base.mu`` - Base template wrapping all pages
+- ``front.mu`` - Front page listing all groups
+- ``group.mu`` - Group page listing repositories
+- ``repo.mu`` - Repository overview page
+- ``releases.mu`` - Release list page
+- ``release.mu`` - Release details page
+- ``tree.mu`` - File browser pages
+- ``blob.mu`` - File content display
+- ``commits.mu`` - Commit history listing
+- ``commit.mu`` - Individual commit detail page
+- ``refs.mu`` - Branches and tags listing
+- ``stats.mu`` - Statistics page
+
+Templates can include the following variables:
+
+- ``{PAGE_CONTENT}`` - The main content of the page (required)
+- ``{NODE_NAME}`` - The configured node name
+- ``{NAVIGATION}`` - Breadcrumb navigation links
+- ``{VERSION}`` - The rngit version number
+- ``{GEN_TIME}`` - Page generation time
+
+**Dynamic Templates**
+
+Templates can be made executable to generate dynamic content. If a template file has the executable bit set, it will be executed and its stdout used as the template content.
+
+**Icon Sets**
+
+By default, the page server uses Nerd Font icons. If you prefer simpler icons or your terminal does not support Nerd Fonts, you can enable Unicode icons instead:
+
+.. code:: text
+
+  [pages]
+  serve_nomadnet = yes
+  unicode_icons = yes
+
+**Repository Statistics**
+
+When statistics recording is enabled (see the ``record_stats`` configuration option), the page server can display activity charts for each repository. The statistics page shows:
+
+- Total and peak views, fetches and pushes
+- Daily activity charts over a 90-day period
+- Combined activity visualization
+
+To view statistics, a user must have the ``s`` (stats) permission for the repository. See the Access Configuration section for details on setting permissions.
+
+**Repository Thanks**
+
+The page server includes a "Thanks" feature that allows users to express appreciation for a repository. On each repository page, a "Thanks" link is displayed showing the current thanks count. Clicking this link registers a thank you for the repository.
+
+**Configuration Example**
+
+A complete page server configuration might look like this:
+
+.. code:: text
+
+  [rngit]
+  node_name = My Git Server
+  announce_interval = 360
+  record_stats = yes
+
+  [repositories]
+  public = /var/git/public
+  internal = /var/git/internal
+
+  [access]
+  public = r:all
+  internal = rw:9710b86ba12c42d1d8f30f74fe509286
+
+  [pages]
+  serve_nomadnet = yes
+  unicode_icons = no
+
+
+Release Management
+==================
+
+In addition to hosting Git repositories, ``rngit`` provides a complete release management system. This allows you to publish versioned releases with associated artifacts, release notes and metadata. Releases are managed through the ``rngit release`` subcommand, and are also viewable through the Nomad Network page interface.
+
+**The Release Workflow**
+
+Creating a release involves specifying a Git tag and a directory containing build artifacts or other files to distribute. The ``rngit`` client will open your configured ``$EDITOR`` to compose release notes, then upload all artifacts to the remote repository node.
+
+To create a release, specify the tag name and path to artifacts:
+
+.. code:: text
+
+  $ rngit release create rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo v1.2.0:./dist
+
+This will:
+
+1. Verify that the tag ``v1.2.0`` exists in the repository
+2. Open your editor to write release notes
+3. Upload all files from the ``./dist`` directory
+4. Publish the release
+
+If no ``$EDITOR`` environment variable is set, ``rngit`` will try to use ``nano``, ``vim`` or ``vi``. The editor will show a template with instructions. Lines starting with ``#`` will be ignored, and if the remaining content is empty after stripping comments, the release creation will be cancelled.
+
+**Release Storage & Structure**
+
+Releases are stored on the server in a directory named ``repo_name.releases`` next to the bare repository. Each release is a subdirectory containing:
+
+- ``META`` - Release metadata in ConfigObj format
+- ``RELEASE.md`` or ``RELEASE.mu`` - Release notes
+- ``artifacts/`` - All uploaded files
+- ``THANKS`` - Appreciation count from users
+
+**Listing Releases**
+
+To view all releases for a repository:
+
+.. code:: text
+
+  $ rngit release list rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo
+
+  Tag          Status     Created              Objs  Notes
+  ------------------------------------------------------------------
+  v1.2.0       published  2025-01-15 14:32     3     Another release
+  v1.1.0       published  2024-12-03 09:15     2     Bug fix release
+  v1.0.0       published  2024-10-20 16:45     2     Initial release
+
+**Viewing Release Details**
+
+To see full information about a specific release:
+
+.. code:: text
+
+  $ rngit release view rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo v1.2.0
+
+  Release : 0.9.2        
+  Status  : published
+  Created : 2026-05-04 23:53:09
+  Thanks  : 5
+
+  Release Notes
+  =============
+
+  Version 1.2.0 release notes...
+
+  Artifacts (4)
+  =============
+    - myapp-1.2.0.tar.gz (1.5 MB)
+    - myapp-1.2.0.zip (1.6 MB)
+    - checksums.txt (256 B)
+
+**Deleting Releases**
+
+To remove a release:
+
+.. code:: text
+
+  $ rngit release delete rns://50824b711717f97c2fb1166ceddd5ea9/public/myrepo v1.2.0
+
+  Are you sure you want to delete release 'v1.2.0'? [y/N]: y
+  Release v1.2.0 deleted
+
+**Requirements & Validation**
+
+- The specified tag must exist in the remote repository
+- You must have ``release`` permission for the repository
+- The target artifacts directory must exist and contain at least one file
+- Release notes cannot be empty
+
+**Permissions**
+
+Release management requires the ``release`` permission, configured the same way as other repository permissions. In the config file or ``.allowed`` files, use ``rel:target`` to grant release management rights:
+
+.. code:: text
+
+  # In .allowed file or config
+  rel:all          # Allow everyone
+  rel:9710b86...   # Allow specific identity
+  rel:none         # Deny everyone
+
+**Nomad Network Interface**
+
+When the Nomad Network page server is enabled, releases are displayed on a dedicated releases page for each repository. Each release is listed with its tag, creation date, artifact count and a preview of the release notes. Clicking a release shows the full details including formatted release notes and a listing of all artifacts with their sizes.
+
+Only releases with ``published`` status are visible through the Nomad Network interface. Draft releases (if supported in future implementations) would only be visible through the command-line interface.
+
+**All Command-Line Options (rngit release)**

+The rngit Utility
+=================
+
+The ``rngit`` utility provides full Git repository hosting and interaction over Reticulum, as well as many other useful features for software development, collaboration and publishing. It allows you to host Git repositories on Reticulum nodes, interact with remote repositories using standard Git commands through the ``rns://`` URL scheme, and to publish software releases.
+
+The system consists of two parts: The ``rngit`` node that hosts and manages repositories, and the ``git-remote-rns`` helper that enables Git to communicate with rngit nodes. As soon as you have RNS installed on your system, you can transparently use Git with Reticulum-hosted repositories just like any other type of remote. Git over Reticulum uses URLs in the following format: ``rns://DESTINATION_HASH/group/repo``.
+
+If you set a branch to track a Reticulum remote as the default upstream, you can simply use ``git`` as you normally would; all commands work transparently and as expected.
+
+.. warning::
+   **The rngit program is a new addition to RNS!** This functionality was introduced in RNS 1.2.0. While great care has been taken to design a secure, but highly configurable and flexible permission system for allowing many users to interact with many different repositories on a single node, ``rngit`` has not been tested extensively in the wild! Be careful when hosting repositories, especially if they are public or semi-public.
+
+For the full documentation on the `rngit` system, see the :ref:`Using Git Over Reticulum<git-main>` chapter of this manual.

+The rnsh Utility
+================
+
+The ``rnsh`` utility provides a fully interactive remote shell over Reticulum.
+It allows you to establish encrypted, authenticated shell sessions on remote
+systems, complete with terminal emulation, pipe support, and window resizing.
+
+While the ``rnx`` utility is useful for simple remote command execution and
+retrieving output, ``rnsh`` provides a complete interactive terminal experience,
+making it ideal for remote administration and management tasks that require
+real-time interaction, just like SSH does for IP networks.
+
+``rnsh`` operates in two modes: a *listener* mode that accepts incoming
+connections, and an *initiator* mode that connects to a remote listener. Both
+sides authenticate using Reticulum Identities, ensuring that only authorised
+peers can establish sessions.
+
+.. note::
+   ``rnsh`` provides a genuine interactive terminal over Reticulum. It supports
+   full terminal emulation including escape sequences, window resizing, signal
+   forwarding, and piping of standard input, output and error streams. This
+   makes it suitable for running text editors, terminal multiplexers, and any
+   other interactive programs on remote systems.
+
+**Usage Examples**
+
+Start ``rnsh`` in listener mode, accepting connections from specific identities:
+
+.. code:: text
+
+  $ rnsh -l -a 941bed5e228775e5a8079fc38b1ccf3f -a 1b03013c25f1c2ca068a4f080b844a10
+
+You can also specify allowed identity hashes (one per line) in the file
+``~/.rnsh/allowed_identities`` or ``~/.config/rnsh/allowed_identities``, and
+simply run the program in listener mode:
+
+.. code:: text
+
+  $ rnsh -l
+
+Connect to a remote listener from another system:
+
+.. code:: text
+
+  $ rnsh 7a55144adf826958a9529a3bcf08b149
+
+Specify a command to run on the remote system, separating ``rnsh`` options from
+the remote command with ``--``:
+
+.. code:: text
+
+  $ rnsh 7a55144adf826958a9529a3bcf08b149 -- top
+
+Set a default command for the listener, in case the initiator does not supply
+one, or when remote command execution is disabled:
+
+.. code:: text
+
+  $ rnsh -l -- /bin/bash --login
+
+Use the ``-m`` flag to mirror the exit code of the remote process:
+
+.. code:: text
+
+  $ rnsh -m 7a55144adf826958a9529a3bcf08b149 -- /usr/local/bin/check-status
+
+Use the ``-p`` flag to display the identity and destination hash for a listener:
+
+.. code:: text
+
+  $ rnsh -l -p
+
+  Identity     : <984b74a3f768bef236af4371e6f248cd>
+  Listening on : 7a55144adf826958a9529a3bcf08b149
+
+Use a specific identity file rather than the default:
+
+.. code:: text
+
+  $ rnsh -l -i /path/to/identity
+
+Announce the listener destination on startup, and periodically:
+
+.. code:: text
+
+  $ rnsh -l -b 900
+
+The ``-b`` option specifies the announce period in seconds. Use ``0`` to
+announce only once at startup.
+
+**Authentication & Authorisation**
+
+By default, ``rnsh`` requires that connecting initiators identify themselves
+with a Reticulum Identity whose hash is present in the list of allowed
+identities. Allowed identities can be specified on the command line with the
+``-a`` option, and can be used multiple times:
+
+.. code:: text
+
+  $ rnsh -l -a 941bed5e228775e5a8079fc38b1ccf3f -a 1b03013c25f1c2ca068a4f080b844a10
+
+You can also maintain a list of allowed identity hashes in the file
+``~/.rnsh/allowed_identities`` or ``~/.config/rnsh/allowed_identities``,
+with one hex hash per line. This file is reloaded every time a new connection
+is received, so changes take effect immediately without restarting ``rnsh``.
+
+If you want to accept connections from any identity (for testing or in fully
+trusted environments), you can disable authentication with the ``-n`` option:
+
+.. code:: text
+
+  $ rnsh -l -n
+
+.. warning::
+   Disabling authentication with ``-n`` means that **any** Reticulum peer that
+   can reach your listener will be able to execute commands on your system. Only
+   use this option if you *really* know what you're doing.
+
+**Remote Command Control**
+
+When running in listener mode, ``rnsh`` allows you to control how remote
+commands are handled:
+
+- By default, the listener accepts the command sent by the initiator. If the
+  initiator does not supply a command, the listener's default shell is used.
+
+- Use ``-C`` (``--no-remote-command``) to disable execution of commands received
+  from the initiator. Only the listener's default command (or the command
+  specified after ``--``) will be executed:
+
+.. code:: text
+
+  $ rnsh -l -C -- /usr/local/bin/safe-script
+
+- Use ``-A`` (``--remote-command-as-args``) to append the initiator's command
+  to the listener's default command instead of replacing it. This can be useful
+  for restricting the remote to a specific program while still allowing the
+  initiator to pass arguments:
+
+.. code:: text
+
+  $ rnsh -l -A -- /usr/bin/top
+
+**Service Names**
+
+When running in listener mode, ``rnsh`` uses a service name to differentiate
+between multiple listener instances that may share the same identity. By
+default, the service name is ``default``. You can specify a different service
+name with the ``-s`` option:
+
+.. code:: text
+
+  $ rnsh -l -s monitoring
+
+This allows you to run multiple listeners on the same node, each with a
+different service name and purpose.
+
+**Initiator Options**
+
+When connecting to a remote listener, several options are available:
+
+- Use ``-N`` (``--no-id``) to disable sending your identity to the remote
+  listener. Note that the listener must have authentication disabled (``-n``)
+  for the connection to succeed in this case.
+
+- Use ``-m`` (``--mirror``) to make the initiator return with the exit code of
+  the remote process, rather than always returning ``0``.
+
+- Use ``-w`` (``--timeout``) to specify the connection and request timeout in
+  seconds. By default, the timeout matches the Reticulum path request timeout.
+
+**Identity & Destination**
+
+The default identity file for ``rnsh`` is stored at
+``~/.reticulum/identities/rnsh``, but you can specify a different one with the
+``-i`` option, which will be created if it does not already exist:
+
+.. code:: text
+
+  $ rnsh -l -i /path/to/identity
+
+To display the identity and destination information for a listener, use the
+``-p`` option. When combined with ``-l``, both the identity and the listening
+destination hash are displayed:
+
+.. code:: text
+
+  $ rnsh -p
+
+  Identity     : <984b74a3f768bef236af4371e6f248cd>
+
+  $ rnsh -l -p
+
+  Identity     : <984b74a3f768bef236af4371e6f248cd>

+Like other Reticulum utilities, ``rnsh`` supports the ``-v`` and ``-q`` flags
+to increase or decrease logging verbosity. Multiple flags can be specified to
+further adjust the log level. The default log level is ``INFO`` for listeners
+and ``ERROR`` for initiators.
+
+.. code:: text
+
+  $ rnsh -l -vv       # Listener with debug-level output
+  $ rnsh -q 7a55144adf826958a9529a3bcf08b149   # Quiet initiator
+
+By default, all log output is routed to ``~/.rnsh/logfile`` for initiators.
+
+**Escape Sequences**
+
+During an active ``rnsh`` session, the following escape sequences are
+available. These are only recognised immediately after a newline character:
+
+- ``~~`` - Send a literal tilde character
+- ``~.`` - Terminate the session and exit immediately
+- ``~L`` - Toggle line-interactive mode
+- ``~?`` - Display the escape sequence quick reference

+****************
+Zen of Reticulum
+****************
+
+The Illusion Of The Center
+==========================
+
+For the better part of a generation, we have been taught to visualize the digital world through the lens of hierarchy. The mental maps we carry are dominated by a single, misleading image: **The Cloud**.
+
+We imagine the network as a vast, ethereal space "up there" or "out there". A centralized repository of services and data to which we, the lowly clients, must connect. We build our software with this assumption hardcoded into our logic: *There is a server. The server has the authority. The server knows the way. I must find the server to function*.
+
+This is the Client-Server mental model, and it is the primary obstacle to understanding Reticulum.
+
+Fallacy Of The Cloud
+--------------------
+
+The first step in the Zen of Reticulum is to realize that *there is no cloud*. There is only other people's computers. When you build for the cloud, you are building *for* a landlord. You are accepting that your application's existence is conditional on the permission, uptime, and continued goodwill of a central authority.
+
+In Reticulum, you must shift your thinking from "connecting to" to "being among". Reticulum is not a service you subscribe to - *it is a fabric you inhabit*. There is no "up there". There is only *here* and *there*, and the space between them is peer-to-peer.
+
+Decentralization Or Uncentralizability?
+---------------------------------------
+
+It is common to hear the word "decentralized" thrown around in modern tech circles. But often, this is merely a marketing term for "slightly distributed centralization". A blockchain with a few dominant miners, or a federated protocol with a few giant servers. *In practice*, it's still centralized. It simply has a few centers instead of one.
+
+Reticulum goes further. It wants **Uncentralizability**.
+
+This is not a wishful political stance, but a foundational mathematical characteristic of the protocol, onto which everything else has been built. Reticulum assumes that every peer on the network is potentially hostile, and every link is potentially compromised. It is designed with no "privileged" nodes. While some nodes may act as Transport Instances - forwarding traffic for others - they do so *blindly*, and they only know about their immediate surroundings, and nothing more. They route based on cryptographic proofs, not on administrative privilege. They cannot see who is talking to whom, nor can they selectively manipulate traffic without breaking their own ability to route entirely.
+
+The system is designed to make hierarchy structurally impossible. You cannot hijack an address, because there is no central registry to hijack. You cannot block a user, because there is no central switch to flip. You can offer paths through the network, but you can't force anyone to use them.
+
+Death To The Address
+--------------------
+
+To break free of the center, you must also let go of the concept of the "Address".
+
+In the IP world, an address is a location. It is a coordinate in a *deeply hierarchical* and static grid. If you move your computer to a different house, your address changes. If your router reboots, your address might change. Your *identity* is bound to your *location*, and therefore, it is fragile, and easily controlled.
+
+Reticulum abolishes this link between *Identity* and *Location*.
+
+In Reticulum, an address is not a place; it is a **Hash of an Identity**. It is a cryptographic representation of *who* you are, not *where* you are. Because of this, your address is portable. You can take a laptop from a WiFi cafe in Berlin, to a LoRa mesh in the mountains, to a packet radio link on a boat, and your "address" - your *Destination Hash* - never changes.
+
+The network does not route to a place; it routes to a *person* (or a machine). When you send a packet, you are not targeting a coordinate in a grid; you are encrypting a message for a specific entity. The network dynamically discovers where that entity currently resides, and it does so in a way where no one really knows where that entity is actually located physically.
+
+**Consider:**
+
+- **The Old Way:** *"I am at* ``192.168.1.5``. *Come find me"*.
+- **The Zen Way:** *"I am* ``<327c1b2f87c9353e01769b01090b18f2>``. *Wherever I am, my peers can reach me"*.
+
+Once you stop thinking about servers and start thinking about portable identities, where everyone can always reach everyone else directly, the illusion of the center fades away. You realize there *is* no center holding the network together. No coordinators or bureaucrats required. The network is simply the sum of its peers, communicating directly, sovereignly, and without a master.
+
+
+Physics Of Trust
+================
+*Paranoia Is A Great Design Principle*
+
+If we accept that there is no center - that the network is a chaotic, peer-to-peer mesh - we are forced to confront a terrifying reality: **There is no one guarding the door**.
+
+In the traditional networking mindset, we rely on the concept of the "trusted core". We assume our local coffee shop WiFi is safe, or that the backbone providers are neutral custodians. We build our security like a castle: strong walls on the outside, soft and trusting on the inside. We use encryption only when we step out into the "wild" internet.
+
+Hostile Environments
+--------------------
+
+The Zen of Reticulum requires you to invert this. You must assume that *every* environment is hostile. This isn't cynicism, just uncaring physics.
+
+When you transmit information over radio waves, you are shouting into a crowded room. Anyone can listen. When you traverse the internet, your packets pass through routers controlled by strangers, corporations, and state actors. Assuming privacy in this environment without cryptographic protection is not optimism but gross negligence.
+
+Reticulum is built on the premise that every link is tapped, and every peer is a potential adversary. If your system cannot survive an adversary owning the physical layer, it cannot survive at all.
+
+But this is the paradox: By assuming the network is hostile, you make it safe. When you accept the dangers for what they are, they become manageable. When you stop trusting the infrastructure and start trusting the math, you eliminate the single point of failure: Human integrity.
+
+Encryption Is Not A Feature
+---------------------------
+
+In the world of TCP/IP, encryption is an afterthought. It is a layer we slap on top of the protocol (HTTPS, TLS) to patch the security holes of the original design. It is a "feature" you sometimes *enable* for "sensitive data". This is fundamentally flawed, since all data is sensitive.
+
+In Reticulum, encryption is **gravity**.
+
+It is not optional. It is not a plugin. It is the *fundamental force that allows the network to exist*. If you were to strip the encryption from Reticulum, the routing would break. The Transport system uses cryptographic signatures and entropy to verify paths and pass information. If packets were plaintext, intermediate nodes could not prove that a route was valid, nor could endpoints prevent spoofing or tampering.
+
+In Reticulum, the entropy of the encrypted packet *is* the routing logic.
+
+To ask for a version of Reticulum without encryption is like asking for a version of the ocean without liquid. You are not asking for a feature change; you're asking for a different physical universe. We design for a universe where information has mass, structure, and integrity.
+
+Zero-Trust Architectures
+------------------------
+
+We must unlearn our reliance on **Institutional Trust**.
+
+For decades, we have been trained to trust authorities. We trust a website because a chain of Certificate Authorities (companies we don't know) vouches for it. We trust an app because it is in an app store (run by a corporation we don't control). We trust a message because it comes from a phone number assigned by a telecom. Yet, everything in our digital information sphere today is more untrustworthy and risky than a medieval second-hand underwear market.
+
+Reticulum replaces institutional trust with **Cryptographic Proof**.
+
+In Reticulum, you do not trust a node because it has a nice hostname or because it is listed in a directory. You trust it because it holds the private key corresponding to the Destination Hash you are communicating with. This trust is binary, mathematical, and **absolute**. Either the signature matches, or it does not. There is no "maybe".
+
+This shift moves the power from the institution to the individual. You become the ultimate arbiter of your own trust relationships. You decide which keys to accept, which paths to follow, and which identities to recognize.
+
+**Consider:**
+
+- **The Old Way:** *"I trust this site because the browser says the lock icon is green"*.
+- **The Zen Way:** *"I trust this destination because I have verified its hash fingerprint out-of-band, and the math confirms the signature"*.
+
+When you internalize the Physics of Trust, you stop looking for protection from firewalls, VPNs, and Terms of Service agreements. You realize that true security comes from the design of the protocol itself. You can stop trusting the cloud, and you start trusting the code - because you can verify it yourself.
+
+
+Merits Of Scarcity
+==================
+*Every Bit Counts*
+
+We have grown addicted to abundance. In the modern digital ecosystem, bandwidth is treated as an endless, flat ocean. We stream high-definition video without a thought, we ship entire libraries of code just to render a single button, and we measure performance in gigabits per second. This abundance has hollowed out our craft. When constraints vanish, efficiency dies, and with it, a certain kind of Clarity and Quality.
+
+Reticulum asks you to step out of the ocean and onto the tightrope.
+
+The Bandwidth Fallacy
+---------------------
+
+The Zen of Reticulum requires the realization that **5 bits per second is a valid speed**.
+
+To a modern developer, this sounds like paralysis. But there is a profound freedom in limits: When you have a gigabit connection, you can be incredibly sloppy. You can be wasteful. You can push your problems onto the infrastructure. *"It’s slow? Get a faster router"*.
+
+But on a high-latency, low-bandwidth link (be it a noisy HF radio channel or a tenuous LoRa hop) you cannot push problems anywhere. You must solve them. The network does not negotiate with waste.
+
+This forces a shift from consumption to interaction. You are no longer, then, consuming a service provided by a fat pipe; you are engaging in a careful negotiation with the physical medium. The medium becomes a partner in the conversation, not just a dumb conduit. You suddenly need to *understand the world to be in it*.
+
+Cost Of A Byte
+--------------
+
+In a scarce economy, a byte is not just data, but energy, time, and space.
+
+Every byte you transmit consumes battery life on a solar-powered node. It occupies valuable airtime that could have been used by another peer. It represents a measurable slice of the electromagnetic spectrum.
+
+When you internalize this, you begin to write code differently. You stop asking, "How much data can I send?" and start asking, "What is the *minimum* amount of information required to convey this intent? How can I best utilize my informational entropy?"
+
+This is where the elegance of Reticulum shines. The protocol is designed to strip away the non-essential. A link establishment takes three very small packets. A destination hash fits in 16 bytes. The overhead is vanishingly small, leaving almost the entire channel for the message itself.
+
+**Consider:**
+
+- **The Old Way:** *"I need to send a status update. I'll send a JSON object with metadata, timestamps, and user profile info (15KB)."*
+- **The Zen Way:** *"I need to send a status update. I'll send a single byte representing the state code. The context is already known."*
+
+This is of course optimization, but more importantly, *it is a form of respect*. Efficiency in a shared medium is an act of stewardship. By taking only what you need from the network, you leave room for others. The network listens to those who speak with purpose.
+
+Flow & Time
+-----------
+
+Scarcity also teaches us about time. We have become addicted to the *synchronous* now - the instant ping, the real-time stream. But Reticulum embraces *asynchronous* time.
+
+When links are intermittent and latency is measured in minutes or hours, "real-time" is an illusion. Reticulum doesn't encourage **Store and Forward** as a mere fallback, but as a primary mode of existence. You write a message, it propagates when it can, and it arrives when it arrives.
+
+This changes the psychological texture of communication. It removes the anxiety of the immediate response. It allows for contemplation. You are not demanding the recipient's attention *right now*; you are placing a gift in their path, to be found when they are ready.
+
+By designing for delay, you design for resilience. You are no longer building a house of cards that collapses when a single packet drops. You are building a stone arch that distributes the load *over time*.
+
+Liberation From Limits
+----------------------
+
+There is a strange optimism in scarcity. When you are forced to work within strict constraints, you are forced to prioritize. *You* must decide what truly matters. *That* is the real core of agency.
+
+In the infinite fantasy world of The Cloud, everything is urgent, so nothing is. In the economy of Reticulum, the cost of transmission forces you to weigh the value of your message. Do you really need to send that heart beat? Is that photo essential?
+
+When you strip away the noise, what remains is *signal*.
+
+This discipline creates a different kind of developer. It creates a craftsman who understands that the best code is the code you don't have to write. It creates a user who understands that the most powerful message is the one that is *understood*, not the one that is loudest. In the world of Reticulum, you are not a mere consumer of bandwidth; you are an architect of intent.
+
+
+Sovereignty Through Infrastructure
+==================================
+**Be Your Own Network**
+
+We live in an era of digital tenancy. We lease our connectivity from ISPs. We rent our storage from cloud providers. We even borrow our identity from social media platforms. We are tenants in a house we did not build, governed by rules we did not write, subject to eviction at the whim of a landlord who has never met us.
+
+The Zen of Reticulum is the realization that you *can* own the house.
+
+A Carrier-Grade Fallacy
+-----------------------
+
+For decades, we have been gaslit into believing that networking is really not just hard, but impossible. It is presented as a dark art reserved for telcos and billionaires, requiring millions of dollars of fiber optics, climate-controlled data centers, and armies of engineers. We are told that building reliable infrastructure is "too complex" for the individual or small organization.
+
+This is a big, fat lie.
+
+Physics is simple. A radio wave needs a transmitter and a receiver. A packet needs a path. The "complexity" of the modern internet is largely bureaucratic - a mountain of billing systems, regulatory capture, and legacy cruft designed to keep the gatekeepers in power.
+
+Reticulum strips away the bureaucracy. It runs on hardware that costs the price of a dinner. It runs on spectrum that is free to use. It demonstrates that a robust, planetary-scale network does not require a Fortune 500 company. It requires only the will to deploy, and the distributed, uncoordinated efforts of many individuals.
+
+Personal Infrastructure
+-----------------------
+
+This is where the rubber meets the road. You can read about Reticulum, you can understand the theory, but the insights only arrive when you plug in a radio and run a Transport Node. Suddenly, you are no longer a consumer. You're an operator.
+
+This shift is subtle but profound. When you run your own infrastructure, the network ceases to be a service that is provided *to* you. It becomes a space that you *inhabit*. You become responsible for the flow of information. You gain an intimate understanding of the medium - the way the weather affects the radio waves, the way the topology changes, the way the packets dance through the ether.
+
+There is a quiet competence that comes from this. You stop asking "Is the internet down?" and start asking "Is *my* links up?" You stop waiting for a technician and start checking the logs. This is a form of strength. To understand the system that carries your words is to be free from the mystery that keeps you dependent.
+
+The Ability To Disconnect
+-------------------------
+
+Why go to the trouble? Why buy the radio, write the config, and leave the Pi running in the corner?
+
+Because the old, centralized network is fragile. And because most of us doesn't even really want to be there anymore.
+
+The internet we rely on today is a chain of single points of failure. Cut the undersea cable, and a continent goes dark. Shut down the power grid, and the cloud evaporates. Deprioritize the "wrong" traffic, and the flow of information is strangled.
+
+Sovereignty is the ability to survive the cut, whether or not that cut was an accident or on purpose.
+
+When you build your own infrastructure, you build a lifeline. Reticulum is designed to function over media that the traditional internet cannot touch - bare wires, battery-powered radios, ad-hoc WiFi meshes. When the grid fails, or the censors arrive, or the bill goes unpaid, your Reticulum network continues to hum.
+
+This is not about "dropping out" of society. It is about building a substrate on which an actual *Society* can function.
+
+**Consider:**
+
+- **The Old Way:** "My connection is slow. I should call my ISP and complain."
+- **The Zen Way:** "The path is noisy. I will adjust the antenna or find a better route."
+
+By taking ownership of the infrastructure, you take ownership of your voice. You stop shouting into someone else's megaphone and start building your own. The network is no longer something that happens to you; it is something you make happen.
+
+
+Identity and Nomadism
+=====================
+**A Fluid Self**
+
+In the old world, you are defined by your coordinates. If you are at ``34.109.71.5``, you're *here*. If you unplug the cable and walk down the street, you vanish. Your digital self evaporates because it was tethered to the wall. You are a ghost in the endless machinations of gears, levers and transistors, bound to the hardware, and those that own it.
+
+This creates a subtle, constant anxiety. We are terrified of disconnecting because, in the architecture of the old web, disconnecting is a kind of death.
+
+The Zen of Reticulum offers a different way to be.
+
+Portable Existence
+------------------
+
+In Reticulum, your identity is not a location, or a username granted by a service. It is a cryptographic key - a complex, unique mathematical signature that exists independently of the physical world. You can carry it only in your mind, if you want to.
+
+Think of it less like a street address and more like a name. *A true name*.
+
+If you travel from Berlin to Tokyo, you do not change your name. You are still you. The people who know you can still recognize you. Reticulum applies this principle to the network layer. Your Destination Hash is **invariant**. It travels with you, stored securely on your device, *immutable as a stone*.
+
+This changes the relationship between you and the machine. You are not "logged into" the network via a specific gateway. You *are* the endpoint. The network does not connect to a place; *it converges on you*.
+
+Roaming Nodes
+-------------
+
+This freedom introduces a new concept of time and space: **Nomadism**.
+
+Because your identity is portable, your connectivity can be fluid. You can be sitting at a desk connected to a fiber backbone one moment, and walking through a field connected only to a long-range LoRa mesh the next. To the rest of the network, nothing has changed. Your friends do not need to update your contact info. The messages they send do not bounce back. The network senses the shift in the medium and reroutes the flow of data automatically.
+
+You are no longer a stationary node in a fixed grid. You are a wanderer in a fluid medium.
+
+The interfaces - whether it is WiFi, Ethernet, Packet Radio, or a physical wire - is merely the clothing your node wears. You change it to suit the environment. Underneath, you remain the same. This is the liberation of the protocol. It treats the physical medium as a transient circumstance, not a definition of self.
+
+**Consider:**
+
+- **The Old Way:** *"I lost connection. I have to reconnect to the VPN to tell them where I am now."*
+- **The Zen Way:** *"I moved. The network subtly bends to accomodate this new reality."*
+
+Announcing Presence
+-------------------
+
+How does the network find a wanderer? It listens.
+
+In the IP world, we query directories. We ask a server, "Where is Mark?" The server checks its database and gives us a coordinate. This means that someone, somewhere, is keeping track of you. It assumes and *requires* surveillance.
+
+Reticulum replaces surveillance with **Announces**.
+
+Instead of asking a central authority where you are, you simply state your presence. You broadcast a cryptographic proof: "I am here, and I am who I say I am". This ripples out through the mesh. Your neighbors hear it, update their path tables, and pass it on.
+
+This is a quiet, organic process. It is the digital equivalent of lighting lanterns in the dark. You do not need to chase the light; you let the light find you. It respects your autonomy. You choose when to announce, how often to speak, and to whom. You also choose when to disappear - for but a moment or perpetually.
+
+Anchor In The Flow
+------------------
+
+There is a deep peace in this nomadism. It teaches you that stability does not come from standing still. Stability comes from *internal coherence*.
+
+By holding your own private key, you hold your own center of gravity. The world around you; the infrastructure, the topography and the availability of links can all shift chaotically. Storms can knock out towers. Cables can be cut. The internet can go down.
+
+But as long as you possess your key, you possess your identity. The entire infrastructure can be destroyed and rebuilt, and you are still you. Nothing lasts, yet nothing is lost.
+
+You become a sovereign entity moving through the noise, connected not by the rigidity of cables, but by the fluidity of recognition. The network becomes a place you inhabit, rather than a utility you subscribe to: You are at home in the ether.
+
+
+Ethics Of The Tool
+==================
+**Technology With Conscience**
+
+You have unlearned the center. You have accepted the physics of trust. You have embraced the economy of scarcity and the freedom of unbound nomadism. You are standing in a new space. Now, look at the tool in your hand.
+
+In the old world, we were taught that technology is neutral. We are told that "guns don't kill people, people do", or that a component is just a component, indifferent to what its combinatorial potential is. This is a convenient lie. It serves only to allow the builders to wash their hands of responsibility.
+
+But we know better now. We know that **architecture is politics**, and *politics is control*. The way you build a system determines how it will be used. If you build a system optimized for mass surveillance, you *will* get a panopticon. If you build a system optimized for centralized control, you *will* get a dictatorship. If you build a system optimized for extraction, you *will* get a parasite.
+
+The Zen of Reticulum asserts that a tool is never neutral.
+
+On the very contrary: A tool is intent, **crystallized**.
+
+The Harm Principle
+------------------
+
+Why does the Reticulum License forbid the software from being used in systems designed to harm humans? Is it not just a restriction on freedom?
+
+It is a restriction on *license*, yes, but it is an expansion of *freedom*.
+
+Building powerful tools without a moral compass is in no way virtuous or commendable, it is plain and simple irresponsibility.
+
+A tool that can easily be used to oppress is a real danger to the user. If you build a network that can be turned against you by a tyrant, you are not free. You are merely waiting for the leash to tighten. By encoding the "Harm Principle" into the legal DNA of the reference implementation, we are building a safeguard. We are stating, clearly and immutably, that *this tool* is for **life**, not for death.
+
+This aligns the software with the interests of humanity. It cements that the network cannot be conscripted into a kill-system, a weaponized drone controller, or a torture device without breaking the license and the law. It is a line drawn in the sand - not by a government or external authority, but by the creators of the tool itself.
+
+**Consider:**
+
+- **The Old Way:** *"It's just software. How people use it is not my problem."*
+- **The Zen Way:** *"This software is a habitat. I will not allow it to be used to build a cage."*
+
+It is *your* choice whether to align with this - we are not forcing this stance on anyone. If you choose to align with life over death, with creativity over destruction, we grant you an immensely powerful tool, to own and build with as you please. If you do not, we deny it.
+
+If you do not like this, we most assuredly do not need you here, and you are on your own.
+
+Public Domain Protocol
+----------------------
+
+This leads to a vital distinction: The difference between the *idea* and the *implementation*.
+
+The protocol - the mathematical rules of how Reticulum works - is dedicated to the Public Domain. It belongs to humanity. **No one can own it**. Anyone can implement it, improve it, or adapt it. This is the core idea of free communication, which itself must be forever free.
+
+But the functional, deployed *reference implementation* - the Python code, the maintenance, the years of labor - has a conscience. This distinction is the engine of sustainability. It allows the protocol to be universal, while ensuring that the specific labor of the builders is not hijacked to undermine the foundational intent of the project itself. From this document, it should be very clear what this intent is.
+
+If you want to build a system with Reticulum that manipulates and damages users for profits or targets missiles, you can use the public domain protocol, and start from scratch. But you cannot take our work. You must do your own. This serves as a pillar of accountability. If you want to build a weapon, *you* go and forge the steel yourself, while the world observes. And when the blood is drawn - it is on **your** hands.
+
+Preserving Human Agency
+-----------------------
+
+We live in an era of predatory extraction. The open-source commons is being scraped, ingested, and regurgitated by machine learning algorithms, whose corporate owners seek to replace the very humans who built those commons. Our code, our words, and our creativity is being used to train systems that are specifically designed to make us obsolete, without offering anything else in return than serfdom and leashes.
+
+Reticulum stands against this.
+
+The license protects the software from being used to feed the beast. It draws a hard line: This tool is for *people*. It is for human-to-human connection. It is not a dataset to be strip-mined for the purpose of building a synthetic overlord, puppeteered by a miniscule conglomerate of controllers.
+
+This is a radical act of preservation. By protecting the code from AI appropriation, we are protecting space for human agency. We are ensuring that there remains a digital realm where the actors are flesh, blood and soul, where decisions are made by minds, not overlords hiding behind models.
+
+When you use Reticulum, you are using a tool that respects you. It does not see you as a product to be tracked. It does not see your data as fuel for an algorithm. It sees you as a sovereign, equal peer.
+
+This changes the foundational premise of using the technology. It restores dignity to the interaction. You are not the user of a service; you are a participant in a mutual covenant. The tool aligns with your autonomy, rather than eroding it.
+
+In this way, ethics is not a restriction, but a foundation. It is the foundation that helps ensure the network will still belong to you tomorrow.
+
+
+Design Patterns For Post-IP Systems
+===================================
+**Practical Philosophy for Developers**
+
+The philosophy is useless if it cannot be hammered into code. The metaphors we have explored - nomadism, scarcity, trust - are not just poetry, but real-world engineering constraints. When you sit down to write software for Reticulum, these concepts must shape the very structure of your application.
+
+We are now moving from the *why* to the *how*. This is where the abstract becomes concrete, and where you will see the true depth of the patterns we have been weaving.
+
+Store & Forward
+---------------
+
+The web has trained us to be impatient. We write synchronous code. We fire a request and we wait, blocking the UI, holding our breath. If the response doesn't come in 250 milliseconds, we show a spinner. If it doesn't come in five seconds, we show an error. We treat network connectivity as a binary state: either we are "online" or we are "broken".
+
+This is brittle. It is a rejection of reality.
+
+In Reticulum, connectivity is a spectrum, and presence is asynchronous. If at all applicable to your intent, you must design your applications to embrace **Store & Forward**.
+
+Instead of demanding an immediate answer, your application should act as a patient participant. You create a message for someone or something in the mesh. The network holds it. It carries it from node to node, perhaps over hours or days, waiting for the recipient to appear. When they finally surface, the message is delivered. This requires a shift from "request/response" to "event/handler". How exactly you do this is a challenge for you to solve intelligently within your problem domain, but Reticulum-based systems already exist that does this extremely well, and you can use them for inspiration.
+
+**Consider:**
+
+- **The Old Way:** ``Connect() -> Send() -> Wait() -> Crash if timeout.``
+- **The Zen Way:** ``Send() -> Continue living. -> Receive() when it arrives.``
+
+This changes the user experience profoundly. It removes the anxiety of the loading bar. It creates a sense of continuity. The user is not "waiting for the network"; they are interacting with a persistent log of communication that lives in the network itself.
+
+Naming Is Power
+---------------
+
+In the IP world, we are slaves to the Domain Name System. We rely on a hierarchy of registrars to map human-readable names to machine-readable addresses. This hierarchy is a choke point. If the registrar revokes your domain, or if the DNS server goes down, you vanish.
+
+Reticulum dissolves this hierarchy with **Hash-based Identity**.
+
+In this design pattern, a name is not a string you look up; it is a cryptographic destination you verify. When you design for Reticulum, you stop asking the user for a URL and start asking for a Destination or Identity Hash.
+
+This feels strange at first. A hash like ``<83b7328926fed0d2e6a10a7671f9e237>`` looks alien compared to ``myfriend.com``. But that alienness is the armor. It **cannot** be spoofed. It **cannot** be censored by a registrar. It is **absolute**.
+
+Designing for this means shifting your UI metaphors. You are no longer browsing a web of pages; you are managing a ledger of keys. You are building an "Address Book" that is actually a keyring. The names are given by the user, and the power stays with them. That hashes look complex is directly analogous to the strengths of the bonds formed by their use. It forces the user to engage in a moment of verification, an out-of-band handshake, which restores the human element of trust that SSL certificates stripped away.
+
+The Interface Is The Medium
+---------------------------
+
+One of the most liberating patterns in Reticulum is **Transport Agnosticism**.
+
+In traditional networking, your code is often littered with transport logic. "Am I on WiFi? Check bandwidth. Am I on Cellular? Check data plan. Am I on Ethernet?". You are constantly micromanaging the pipe.
+
+In Reticulum, you write to the API, and the API writes to the medium. You send a packet to a Destination. You do not care if that packet travels over a TCP tunnel, a LoRa radio wave, or a serial wire interface. That is the stack's concern.
+
+This allows you to write **Universal Applications**.
+Imagine a messaging app. You write it once. It works on a laptop connected to fiber. It works on a phone in the city using WiFi. And, without a single line of code changed, it works on a device in the wilderness, talking only to other devices via radio.
+
+The pattern is simple: **Never code to the hardware. Code to the intent.**
+
+**Consider:**
+
+- **The Old Way:** ``socket.connect(ip, port)``, and then a whole lot more
+- **The Zen Way:** ``RNS.Packet(destination, data).send()``
+
+By abstracting the medium, you make your software immortal to changes in infrastructure. The user might switch from a 4G hotspot to a HF modem tomorrow. Your software doesn't need to know. It simply continues the conversation.
+
+Emergent Patterns
+-----------------
+
+When you combine these patterns - *Store & Forward*, *Hash-based Identity*, and *Transport Agnosticism* - you create software that feels fundamentally different.
+
+It feels *grounded*. It doesn't flicker when the signal drops. It doesn't panic when the server is down. It has weight. It has persistence. It has *relevance*.
+
+You are no longer building a "client" that begs a "server" for attention. You are building an autonomous agent that exists within the mesh. It speaks when it needs to, listens when it can, and carries its identity with it wherever it goes.
+
+This is the culmination of the Zen. The code is not just a set of instructions: It is a behavioral envelope. It is a way of *being* in the network.
+
+
+Fabric Of The Independent
+=========================
+
+We have stripped away the illusions. We have seen that the center is empty, that trust *must* be hard, that resources are finite, and that we must own our infrastructure. We have seen that tools have ethics and that our identity can move fluidly.
+
+This is a reclaiming of the commons. For too long, we have allowed the most vital substrate of human society - *our ability to speak to one another* - to be colonized by entities that do not share our interests. We have allowed the architecture of our communication to be designed by accountants rather than architects.
+
+We are taking it back. Not by petitioning the masters, but by building the new world within, over, under and around the shell of the old.
+
+The Work Is Finished
+--------------------
+
+The heavy lifting is done.
+
+The protocol is in the public domain, a gift to humanity that can never be taken away. The software is written, tested, and running on devices scattered across the globe. The manual lies open before you. The source code for the reference implementation is now distributed on hundreds of thousands of devices across the planet. No one can delete or destroy it. The hardware is accessible and abundant.
+
+It was a hard road to get here, but we got here. Now, there is no roadmap committee waiting for approval. There is no venture capital dictating the user experience. There is no CEO to sign off on the next feature release.
+
+There is only you.
+
+The barrier to entry is no longer complexity: It is the mere habit of dependency. You were conditioned to wait. Wait for the app update. Wait for the ISP to fix the line. Wait for the platform to allow the post. Wait for the government to change the policies. Wait for the likes. Wait for the revolution to be televised.
+
+The revolution never was televised.
+
+It is packetized.
+
+Open Sky
+--------
+
+The future of this technology is a construction project.
+
+It looks like a single node on a windowsill, listening to the static. It looks like a message sent to a neighbor, bypassing the noise of the commercial web. It looks like a community mesh that grows, link by link, hop by hop, carried by hands that care more about connection than profit.
+
+You have the blueprints. You have the tools. You have the philosophy. The noise of the old world has fallen away, leaving you with the quiet clarity of the open spectrum.
