+## Installing
+
+To get started, follow the [release installation guide](./installing-from-release.md). Then run the installer with the following command:
+
+
+```bash
+# For Orbic:
+./installer orbic --admin-password 'mypassword'
+
+# For Kajeet/Smartspot:
+./installer orbic --admin-password '$m@rt$p0tc0nf!g'
+
+# Note: the arguments --admin-username 'myusername' and --admin-ip 'mydeviceip'
+#       may be required if different from the default.
+
+# Or install over USB if you want ADB and a root shell (not recommended for most users)
+./installer orbic-usb
+```
+
+* The password is the one used to log in to the device's admin menu. You can reset the password by pressing the button under the back case until the unit restarts.

+* On Verizon Orbic, the default password is the WiFi password.
+* On Kajeet/Smartspot devices, the default password is `$m@rt$p0tc0nf!g`
