 Nomad Network does not need any connections to the public internet to work. In fact, it doesn't even need an IP or Ethernet network. You can use it entirely over packet radio, LoRa or even serial lines. But if you wish, you can bridge islanded networks over the Internet or private ethernet networks, or you can build networks running completely over the Internet. The choice is yours.
 
+If you'd rather want to use an LXMF client with a graphical user interface, you may want to take a look at [Sideband](https://github.com/markqvist/sideband), which is available for Linux, Android and macOS.

 ## Notable Features
  - Encrypted messaging over packet-radio, LoRa, WiFi or anything else [Reticulum](https://github.com/markqvist/Reticulum) supports.
  - Zero-configuration, minimal-infrastructure mesh communication

+The first time the program is running, you will be presented with the **Guide section**, which contains all the information you need to start using Nomad Network.
 
 To use Nomad Network on packet radio or LoRa, you will need to configure your Reticulum installation to use any relevant packet radio TNCs or LoRa devices on your system. See the [Reticulum documentation](https://markqvist.github.io/Reticulum/manual/interfaces.html) for info. For a general introduction on how to set up such a system, take a look at [this post](https://unsigned.io/private-messaging-over-lora/).
 
-If you want to try Nomad Network without building your own physical network, you can connect to the [Unsigned.io RNS Testnet](https://github.com/markqvist/Reticulum#public-testnet) over the Internet, where there is already some Nomad Network and LXMF activity.

 ### Install on Android
 You can install Nomad Network on Android using Termux, but there's a few more commands involved than the above one-liner. The process is documented in the [Android Installation](https://markqvist.github.io/Reticulum/manual/gettingstartedfast.html#reticulum-on-android) section of the Reticulum Manual. Once the Reticulum has been installed according to the linked documentation, Nomad Network can be installed as usual with pip.
