 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.
 
 ### Feature roadmap
- - Access control and authentication for nodes, pages and files
  - Network-wide propagated bulletins and discussion threads
- - Geospatial information sharing and collaborative maps
-
-## Dependencies:
- - Python 3
- - RNS
- - LXMF
+ - Collaborative maps and geospatial information sharing
+ - Facilitation of trade and barter
 
 ## How do I get started?
 The easiest way to install Nomad Network is via pip:
@@ -43,11 +38,59 @@ pip3 install nomadnet
 
 # Run the client
 nomadnet
+
+# Or alternatively run as a daemon, with no user interface
+nomadnet --daemon
+
+# List options
+nomadnet --help
 ```
 
 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.
+
+### 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.
+
+For a native Android application with a graphical user interface, have a look at [Sideband](https://unsigned.io/sideband).
+
+### Nomad Network Daemon with Docker
+
+Nomad Network is automatically published as a docker image on Github Packages. Image tags are one of either `master` (for the latest release) or the version number (eg `0.1.7`) for the specified version number (as tagged in this git repo).
+
+
+```sh
+$ docker pull ghcr.io/markqvist/nomadnet:master
+
+# Run nomadnet interactively without installing it (with default config)
+$ docker run -it ghcr.io/markqvist/nomadnet:master
+
+# Run nomadnet as a daemon, using config stored on the host machine in specific
+# directories, and allowing access to specific numbered ports openned by nomadnet
+# on the host machine on the same port numbers.
+$ docker run -d \
+  -v /local/path/nomadnetconfig/:/root/.nomadnetwork/ \
+  -v /local/path/reticulumconfig/:/root/.reticulum/ \
+  -p 37428:37428 \
+  -p 37429:37429 \
+  ghcr.io/markqvist/nomadnet:master
+```
+
+## Help & Discussion

 ## 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.

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.

 You can use a preprocessor such as PHP, bash, Python (or whatever you prefer) to generate dynamic pages. To do so, just set executable permissions on the relevant page file, and be sure to include the interpreter at the beginning of the file, for example `!#!/usr/bin/python3`!.
 
+>>Authenticating Users
+
+Sometimes, you don't want everyone to be able to view certain pages or execute certain scripts. In such cases, you can use `*authentication`* to control who gets to run certain requests.
+
+To enable authentication for any page, simply add a new file to your pages directory with ".allowed" added to the file-name of the page. If your page is named "secret_page.mu", just add a file named "secret_page.mu.allowed".
+
+For each user allowed to access the page, add a line to this file, containing the hash of that users primary identity. Users can find their own identity hash in the `![ Network ]`! part of the program, under `!Local Peer Info`!. If you want to allow access for three different users, your file would look like this:

+`Faaa

+`=
+``
+
+You can also dynamically generate this list, by making the file executable, and writing a script (in whatever language you want), that prints the list to stdout. Every time someone tries to request the page, Nomad Network will check the allowed identities list, and only grant access to allowed users.
+
+By default, Nomad Network connects anonymously to all nodes. To be able to identify, and access restricted pages, you must allow identifying on a per-node basis. To allow identifying when connecting to a node, you must go to the `!Known Nodes`! list in the `![ Network ]`! part of the program, and enable the `!Identify When Connecting`! checkbox under `!Node Info`!.

 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.

+>Ignoring Destinations
+
+If you encounter peers or nodes on the network, that you would rather not see in your client, you can add them to the `!~/.nomadnetwork/ignored`! file. To ignore nodes or peers, add one 20-character hexadecimal destination hash per line to the file. To unignore one again, simply remove the corresponding entry from the file and restart Nomad Network.

 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:
 
 `c`_https://markqvist.github.io/Reticulum/manual/interfaces.html`_
 `l
 
-If you don't currently have access to the Internet, the default Reticulum configuration file is also full of examples of all the supported interface types, and it should be relatively simple to get a working setup going just from those examples.
+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.
