+Nomad Network allows you to build private and resilient communications platforms that are in complete control and ownership of the people that use them. No signups, no agreements, no handover of any data, no permissions and gatekeepers.
 
 Nomad Network is build on [LXMF](https://github.com/markqvist/LXMF) and [Reticulum](https://github.com/markqvist/Reticulum), which together provides the cryptographic mesh functionality and peer-to-peer message routing that Nomad Network relies on. This foundation also makes it possible to use the program over a very wide variety of communication mediums, from packet radio to fiber optics.

-## Current Status
-The current version of the program should be considered a beta release. The program works well, but there will most probably be bugs and possibly sub-optimal performance in some scenarios. On the other hand, this is the ideal time to have an influence on the direction of the development of Nomad Network. To do so, join the discussion, report bugs and request features here on the GitHub project.

+If there is already an abundance of Propagation Nodes on the network, or the operator simply wishes to host a pageserving-only node, Propagation Node hosting can be disabled in the configuration file.
+
+To view LXMF Propagation nodes that are currently peered with your node, go to the `![ Network ]`! part of the program and press `!Ctrl-P`!. In the list of peered Propagation Nodes, it is possible to break peering with a node by pressing `!Ctrl-X`!. It is also possible to request an immediate delivery sync of all unhandled messages for a node, by pressing `!Ctrl-R`!.
 
 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.

 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.
