 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.

 ## 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.
 
-### 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
-
 ## How do I get started?
 The easiest way to install Nomad Network is via pip:
 
@@ -43,19 +34,108 @@ 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.
+**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.
 
-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.
+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. If you connect to the testnet, you can leave nomadnet running for a while and wait for it to receive announces from other nodes on the network that host pages or services, or you can try connecting directly to some nodes listed here:
+
+ - `abb3ebcd03cb2388a838e70c001291f9` Dublin Hub Testnet Node
+ - `ea6a715f814bdc37e56f80c34da6ad51` Frankfurt Hub Testnet Node
+
+To browse pages on a node that is not currently known, open the URL dialog in the `Network` section of the program by pressing `Ctrl+U`, paste or enter the address and select `Go` or press enter. Nomadnet will attempt to discover and connect to the requested node.
+
+### 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://github.com/markqvist/Sideband).
+
+### Docker Images
+
+Nomad Network is automatically published as a docker image on Github Packages. Image tags are one of either `master` (for the very latest commit) or the version number (eg `0.2.0`) for a specific release.
+
+```sh
+$ docker pull ghcr.io/markqvist/nomadnet:master
+
+# Run nomadnet interactively in a container
+$ docker run -it ghcr.io/markqvist/nomadnet:master --textui
+
+# Run nomadnet as a daemon, using config stored on the host machine in specified
+# directories, and connect the containers network to the host network (which will
+# allow the default AutoInterface to automatically peer with other discovered
+# Reticulum instances).
+$ docker run -d \
+  -v /local/path/nomadnetconfigdir/:/root/.nomadnetwork/ \
+  -v /local/path/reticulumconfigdir/:/root/.reticulum/ \
+  --network host
+  ghcr.io/markqvist/nomadnet:master
+
+# You can also keep the network of the container isolated from the host, but you
+# will need to manually configure one or more Reticulum interfaces to reach other
+# nodes in a network, by editing the Reticulum configuration file.
+$ docker run -d \
+  -v /local/path/nomadnetconfigdir/:/root/.nomadnetwork/ \
+  -v /local/path/reticulumconfigdir/:/root/.reticulum/ \
+  ghcr.io/markqvist/nomadnet:master
+
+# Send daemon log output to console instead of file
+$ docker run -i ghcr.io/markqvist/nomadnet:master --daemon --console

 ## 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.

 By default, Nomad Network will attempt to deliver messages to a peer directly. This happens by first establishing an encrypted link directly to the peer, and then delivering the message over it.
 
-If the desired peer is not available because it has disconnected from the network, this method will obviously fail. In this case, Nomad Network will attempt to deliver the message to a node, which will store and forward it over the network, for later retrieval by the destination peer. The message is encrypted with an ephemeral key before being transmitted to the network, and is only readable by the intended recipient.

The message is encrypted before being transmitted to the network, and is only readable by the intended recipient.
 
 For propagated delivery to work, one or more nodes must be available on the network. If one or more trusted nodes are available, Nomad Network will automatically select the most suitable node to send the message via, but you can also manually specify what node to use.
 
 To select a node manually, go to the `![ Network ]`! part of the program, choose the desired node in the `*Known Nodes`* list, and select the `!< Info >`! button. In the `!Node Info`! dialog, you can specify the selected node as the default propagation node.
 
+By default, Nomad Network will check in with propagation nodes, and download any available messages every 6 hours. You can change this interval, or disable automatic syncronisation completely, by editing the configuration file.
+
+You can always initiate a sync manually, by pressing `!Ctrl-R`! in the `![ Conversations ]`! part of the program, which will open the syncronisation window.
+
 >>Node
 
 A Nomad Network `*node`* is an instance of the Nomad Network program that has been configured to host information for other peers and help propagate messages and information on the network.
 
 Nodes can host pages (similar to webpages) written in a markup-language called `*micron`*, as well as make files and other resources available for download for peers on the network. Nodes also form a distributed message store for offline users, and allows messages to be exchanged between peers that are not online at the same time.
 
-If no nodes exist on a network, all peers will still be able to communicate directly peer-to-peer, but both endpoints of a conversation will need to be available at the same time to converse. When nodes exist on the network, messages will be held and syncronised between nodes for deferred delivery if the destination peer is unavailable. Nodes will automatically discover and peer with each other, and handle synchronisation of message stores.

 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:

+`=
+``
+
+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`!.

+>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 32-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.

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:

+>The Reticulum Testnet
 
 If you have Internet access, and just want to get started experimenting, you are welcome to join the Unsigned.io RNS Testnet. The testnet is just that, an informal network for testing and experimenting. It will be up most of the time, and anyone can join, but it also means that there's no guarantees for service availability.
 
 The Testnet also runs the latest version of Reticulum, often even a short while before it is publicly released, which means strange behaviour might occur. If none of that scares you, add the following interface to your Reticulum configuration file to join:
 
 >>
-[[RNS Testnet Frankfurt]]
+[[RNS Testnet Zurich]]
   type = TCPClientInterface
   interface_enabled = yes
   outgoing = True
-  target_host = frankfurt.rns.unsigned.io
+  target_host = zurich.connect.reticulum.network
-  target_port = 4965
+  target_port = 4242
+<
 
+If you connect to the testnet, you can leave nomadnet running for a while and wait for it to receive announces from other nodes on the network that host pages or services, or you can try connecting directly to some nodes listed here:
+
+ - Dublin Hub Testnet Node    : `!`[abb3ebcd03cb2388a838e70c001291f9]`!
+ - Frankfurt Hub Testnet Node : `!`[ea6a715f814bdc37e56f80c34da6ad51]`!
+
+To browse pages on a node that is not currently known, open the URL dialog in the `![ Network ]`! section of the program by pressing `!Ctrl+U`!, paste or enter the address and select `!< Go >`! or press enter. Nomadnet will attempt to discover and connect to the requested node. You can save the currently connected node by pressing `!Ctrl+S`!.
