 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.
 
+**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 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.

 ## Caveat Emptor
 Nomad Network is beta 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-breaking bugs. If you want to help out, or help sponsor an audit, please do get in touch.

+To host a node on the network, you must enable it in the configuration file, by setting `*enable_node`* directive to `*yes`*. You should also configure the other node-related parameters such as the node name and announce interval settings. Once node hosting has been enabled in the configuration, Nomad Network will start hosting your node as soon as the program is launched, and other peers on the network will be able to connect and interact with content on your node.
 
 By default, no content is defined, apart from a short placeholder home page. To learn how to add your own content, read on.
 
+>>Distributed Message Store
+
+All nodes on the network automatically form a distributed message store that allows users to exchange messages, even when they are not available at the same time.
+
+When Nomad Network is configured to host a node, it also configures itself as an LXMF Propagation Node, and automatically discovers and peers with other propagation nodes on the network. This process is completely automatic and requires no configuration from the node operator.
+
+To view LXMF Propagation nodes that are currently peered with your node, go to the `![ Network ]`! part of the program and press `!Ctrl-P`!.
+
+The distributed message store is resilient to intermittency, and will remain functional as long as at least one node remains on the network. Nodes that were offline for a time will automatically be synced up to date when they regain connectivity.
+
 >>Pages
 
 Nomad Network nodes can host pages similar to web pages, that other peers can read and interact with. Pages are written in a compact markup language called `*micron`*. To learn how to write formatted pages with micron, see the `*Markup`* section of this guide (which is, itself, written in micron). Pages can be linked arbitrarily with hyperlinks, that can also link to pages (or other resources) on other nodes.

 To get the most out of Nomad Network, you will need a terminal that supports UTF-8 and at least 256 colors, ideally true-color. If your terminal supports true-color, you can go to the `![ Config ]`! menu item, launch the editor and change the configuration.
 
+It is recommended to use a terminal size of at least 122x32. Nomad Network will work with smaller terminal sizes, but the interface might feel a bit cramped.
+
 If you don't already have a Nerd Font installed (see https://www.nerdfonts.com/), I also highly recommend to do so, since it will greatly expand the amount of glyphs, icons and graphics that Nomad Network can use. Once you have your terminal set up with a Nerd Font, go to the `![ Config ]`! menu item and enable Nerd Fonts in the configuration instead of normal unicode glyphs.
 
 Nomad Network expects that you are already connected to some form of Reticulum network. That could be as simple as the default UDP-based demo interface on your local ethernet network. This short guide won't go into any details on building networks, but you will find other entries in the guide that deal with network setup and configuration.
