 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.
+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.
+
+**Please Note**: If this is the very first time you use pip to install a program on your system, you might need to reboot your system for the program to become available. If you get a "command not found" error or similar when running the program, reboot your system and try again.
 
 ### Installing on Android
-You can install Nomad Network on Android using Termux, but there's a few extra 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.

 TOPIC_NETWORKS = '''>Network Configuration
 
 Nomad Network uses the Reticulum Network Stack for communication and encryption. This means that it will use any interfaces and communications channels already defined in your Reticulum configuration.
 
 Reticulum supports using many kinds of devices as networking interfaces, and allows you to mix and match them in any way you choose. The number of distinct network topologies you can create with Reticulum is more or less endless, but common to them all is that you will need to define one or more interfaces for Reticulum to use.
 
-If you have not changed the default Reticulum configuration, which should be located at `!~/.reticulum/config`!, you will have one interface active right now. With it, you should be able to communicate with any other peers and nodes that exist on your local ethernet or WiFi network, if your system is connected to one, and most probably nothing else outside of that.
+If you have not changed the default Reticulum configuration, which should be located at `!~/.reticulum/config`!, you will have one interface active right now. With it, you should be able to communicate with any other peers and systems that exist on your local ethernet or WiFi network, if your computer is connected to one, and most probably nothing else outside of that.
 
 To learn how to configure your Reticulum setup to use LoRa radios, packet radio or other interfaces, or connect to other Reticulum networks via the Internet, the best places to start is to read the relevant parts of the Reticulum Manual, which can be found on GitHub:

+If you don't currently have access to the Internet, you can generate a configuration file full of examples of all the supported interface types, by using the command `!rnsd --exampleconfig`!. Using those examples, it should be possible to get a working setup going.
