+The ADS-B history feature persists aircraft messages to Postgres for long-term analysis.
+
+```bash
+# Start with ADS-B history and Postgres
+docker compose --profile history up -d

+
+Set the following environment variables (for example in a `.env` file):

+```bash
+INTERCEPT_ADSB_HISTORY_ENABLED=true
+INTERCEPT_ADSB_DB_HOST=adsb_db
+INTERCEPT_ADSB_DB_PORT=5432
+INTERCEPT_ADSB_DB_NAME=intercept_adsb
+INTERCEPT_ADSB_DB_USER=intercept
+INTERCEPT_ADSB_DB_PASSWORD=intercept
+```
+
+### Other ADS-B Settings
+
+Set these as environment variables for either local installs or Docker:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `INTERCEPT_ADSB_AUTO_START` | `false` | Auto-start ADS-B tracking when the dashboard loads |
+| `INTERCEPT_SHARED_OBSERVER_LOCATION` | `true` | Share observer location across ADS-B/AIS/SSTV/Satellite modules |
+
+**Local install example**
+
+```bash
+INTERCEPT_ADSB_AUTO_START=true \
+INTERCEPT_SHARED_OBSERVER_LOCATION=false \
+python app.py
+```
+
+**Docker example (.env)**
+
+```bash
+INTERCEPT_ADSB_AUTO_START=true
+INTERCEPT_SHARED_OBSERVER_LOCATION=false
+```
+
+To store Postgres data on external storage, set `PGDATA_PATH` (defaults to `./pgdata`):
+
+```bash
+PGDATA_PATH=/mnt/usbpi1/intercept/pgdata
+```
+
+Then open **/adsb/history** for the reporting dashboard.

+```
+
+---
+
+## Navigation

+    </div>
+</div>
+```
+
+---
+
+## Adding a New Module Page
+
+### 1. Create the Route
+
+In `routes/mymodule.py`:
+
+```python
+from flask import Blueprint, render_template
+
+mymodule_bp = Blueprint('mymodule', __name__, url_prefix='/mymodule')
+
+@mymodule_bp.route('/dashboard')
+def dashboard():
+    return render_template('mymodule_dashboard.html',
+                          offline_settings=get_offline_settings())
+```
+
+### 2. Register the Blueprint
+
+In `routes/__init__.py`:
+
+```python
+from routes.mymodule import mymodule_bp
+app.register_blueprint(mymodule_bp)
+```
+
+### 3. Create the Template
+
+Option A: Simple page extending base.html
+```html
+{% extends 'layout/base.html' %}
+{% set active_mode = 'mymodule' %}
+
+{% block title %}My Module{% endblock %}
+
+{% block navigation %}
+{% include 'partials/nav.html' %}
+{% endblock %}
+
+{% block content %}
+<!-- Your content -->
+{% endblock %}
+```
+
+Option B: Full-screen dashboard
+```html
+{% extends 'layout/base_dashboard.html' %}
+{% set active_mode = 'mymodule' %}
+
+{% block dashboard_title %}MY MODULE{% endblock %}
+
+{% block dashboard_content %}
+<!-- Your dashboard content -->
+{% endblock %}
+```
+
+### 4. Add to Navigation
+
+In `templates/partials/nav.html`, add your module to the appropriate group:
+
+```html
+<button class="mode-nav-btn {% if active_mode == 'mymodule' %}active{% endif %}"
+        onclick="switchMode('mymodule')">
+    <span class="nav-icon icon"><!-- SVG icon --></span>
+    <span class="nav-label">My Module</span>
+</button>
+```
+
+Or if it's a dashboard link:
+```html
+<a href="/mymodule/dashboard"
+   class="mode-nav-btn {% if active_mode == 'mymodule' %}active{% endif %}"
+   style="text-decoration: none;">
+    <span class="nav-icon icon"><!-- SVG icon --></span>
+    <span class="nav-label">My Module</span>
+</a>
+```
+
+### 5. Create Stylesheet
+
+In `static/css/mymodule.css`:
+
+```css
+/**
+ * My Module Styles
+ */
+@import url('./core/variables.css');
+
+/* Your styles using design tokens */
+.mymodule-container {
+    background: var(--bg-secondary);
+    border: 1px solid var(--border-color);
+    border-radius: var(--radius-lg);
+    padding: var(--space-4);
+}
+```
+
+---
+
+## Adding a New Dashboard
+
+For full-screen dashboards like ADSB, AIS, or Satellite:
+
+### 1. Create the Template
+
+```html
+<!DOCTYPE html>
+<html lang="en" data-theme="dark">
+<head>
+    <meta charset="UTF-8">
+    <meta name="viewport" content="width=device-width, initial-scale=1.0">
+    <title>MY DASHBOARD // iNTERCEPT</title>
+    <link rel="icon" type="image/svg+xml" href="{{ url_for('static', filename='favicon.svg') }}">
+
+    <!-- Design tokens (required) -->
+    <link rel="stylesheet" href="{{ url_for('static', filename='css/core/variables.css') }}">
+
+    <!-- Fonts -->
+    {% if offline_settings.fonts_source == 'local' %}
+    <link rel="stylesheet" href="{{ url_for('static', filename='css/fonts-local.css') }}">
+    {% else %}
+    <link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&family=JetBrains+Mono:wght@400;500;600&display=swap" rel="stylesheet">
+    {% endif %}
+
+    <!-- External libraries if needed -->
+    <link rel="stylesheet" href="https://unpkg.com/leaflet@1.9.4/dist/leaflet.css" />
+    <script src="https://unpkg.com/leaflet@1.9.4/dist/leaflet.js"></script>
+
+    <!-- Dashboard styles -->
+    <link rel="stylesheet" href="{{ url_for('static', filename='css/responsive.css') }}">
+    <link rel="stylesheet" href="{{ url_for('static', filename='css/mydashboard.css') }}">
+</head>
+<body>
+    <!-- Background effects -->
+    <div class="radar-bg"></div>
+    <div class="scanline"></div>
+
+    <!-- Header -->
+    <header class="header">
+        <div class="logo">
+            <a href="/" style="color: inherit; text-decoration: none;">
+                MY DASHBOARD
+                <span>// iNTERCEPT</span>
+            </a>
+        </div>
+        <div class="status-bar">
+            <a href="#" onclick="history.back(); return false;" class="back-link">Back</a>
+            <a href="/" class="back-link">Main Dashboard</a>
+        </div>
+    </header>
+
+    <!-- Unified Navigation -->
+    {% set active_mode = 'mydashboard' %}
+    {% include 'partials/nav.html' %}
+
+    <!-- Stats Strip -->
+    <div class="stats-strip">
+        <!-- Stats content -->
+    </div>
+
+    <!-- Main Dashboard Content -->
+    <main class="dashboard">
+        <!-- Your dashboard layout -->
+    </main>
+
+    <script>
+        // Dashboard JavaScript
+    </script>
+</body>
+</html>
+```
+
+### 2. Create the Stylesheet
+
+```css
+/**
+ * My Dashboard Styles
+ */
+@import url('./core/variables.css');
+
+:root {
+    /* Dashboard-specific aliases */
+    --bg-dark: var(--bg-primary);
+    --bg-panel: var(--bg-secondary);
+    --bg-card: var(--bg-tertiary);
+    --grid-line: rgba(74, 158, 255, 0.08);
+}
+
+/* Your dashboard styles */
+```
+
+---
+
+## Best Practices
+
+### DO
+
+- Use design tokens for all colors, spacing, and typography
+- Include the nav partial on all pages for consistent navigation
+- Set `active_mode` before including the nav partial
+- Use semantic component classes (`btn`, `panel`, `badge`, etc.)
+- Support both light and dark themes
+- Test on mobile viewports
+
+### DON'T
+
+- Hardcode color values - use CSS variables
+- Create new color variations without adding to tokens
+- Duplicate navigation markup - use the partial
+- Skip the favicon and design tokens imports
+- Use inline styles for layout (use utility classes)
+

 ### Emergency Squawks
 
-The system highlights aircraft transmitting emergency squawks:
-- **7500** - Hijack
-- **7600** - Radio failure
-- **7700** - General emergency
-
-## ADS-B History (Optional)
-
-The history dashboard persists aircraft messages and per-aircraft snapshots to Postgres for long-running tracking and reporting.
-
-### Enable History
-
-Set the following environment variables (Docker recommended):
-
-| Variable | Default | Description |
-|----------|---------|-------------|
-| `INTERCEPT_ADSB_HISTORY_ENABLED` | `false` | Enables history storage and reporting |
-| `INTERCEPT_ADSB_DB_HOST` | `localhost` | Postgres host (use `adsb_db` in Docker) |
-| `INTERCEPT_ADSB_DB_PORT` | `5432` | Postgres port |
-| `INTERCEPT_ADSB_DB_NAME` | `intercept_adsb` | Database name |
-| `INTERCEPT_ADSB_DB_USER` | `intercept` | Database user |
-| `INTERCEPT_ADSB_DB_PASSWORD` | `intercept` | Database password |
-
-### Docker Setup
-
-`docker-compose.yml` includes an `adsb_db` service and a persistent volume for history storage:
-
-```bash
-docker compose up -d
-```
-
-### Using the History Dashboard
-
-1. Open **/adsb/history**
-2. Use **Start Tracking** to run ADS-B in headless mode
-3. View aircraft history and timelines
-4. Stop tracking when desired (session history is recorded)
