+# Nomad Network - Communicate Freely
 
-Communicate Freely.
+Off-grid, resilient mesh communication with strong encryption, forward secrecy and extreme privacy.
 
 ![Screenshot](https://github.com/markqvist/NomadNet/raw/master/docs/screenshots/1.png)
 
-The intention with this program is to provide a tool to that allows you to build private and resilient communications platforms that are in complete control and ownership of the people that use them.
+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 gigabit fiber.
+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.
 
-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 Reticulum networks over the Internet or private ethernet networks, or you can build networks running completely over the Internet. The choice is yours.

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.
  - Zero-configuration, minimal-infrastructure mesh communication
-
-## Current Status
-
-
-The current version of the program should be considered an alpha 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.
-
-Development is ongoing and current features being implemented are:
-
- - Propagated messaging and discussion threads
- - Connectable nodes that can host pages, files and other resources
- - Collaborative information sharing and spatial map-style "wikis"
-
-## Dependencies:
- - Python 3
- - RNS
- - LXMF
+ - Distributed and encrypted message store holds messages for offline users
+ - Connectable nodes that can host pages and files
+ - Node-side generated pages with PHP, Python, bash or others
+ - Built-in text-based browser for interacting with contents on nodes
+ - An easy to use and bandwidth efficient markup language for writing pages
+ - Page caching in browser
 
 ## How do I get started?
 The easiest way to install Nomad Network is via pip:
 
 ```bash
 # Install Nomad Network and dependencies
-pip3 install nomadnet
+pip install nomadnet
 
 # Run the client
 nomadnet
+
+# Or alternatively run as a daemon, with no user interface
+nomadnet --daemon
+
+# List options
+nomadnet --help
 ```
 
-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 for info.
+If you are using an operating system that blocks normal user package installation via `pip`, you can return `pip` to normal behaviour by editing the `~/.config/pip/pip.conf` file, and adding the following directive in the `[global]` section:
+
+```text
+[global]
+break-system-packages = true
+```
+
+Alternatively, you can use the `pipx` tool to install Nomad Network in an isolated environment:
+
+```bash
+# Install Nomad Network
+pipx install nomadnet
+
+# Optionally install Reticulum utilities
+pipx install rns
+
+# Optionally install standalone LXMF utilities
+pipx install lxmf
+
+# Run the client
+nomadnet
+
+# Or alternatively run as a daemon, with no user interface
+nomadnet --daemon
+
+# List options
+nomadnet --help
+```
+
+**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.
+
+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 experimental 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.

+# lxmf_messageboard
+Simple message board that can be hosted on a NomadNet node, messages can be posted by 'conversing' with a unique peer, all messages are then forwarded to the message board.
+
+## How Do I Use It?
+A user can submit messages to the message board by initiating a chat with the message board peer, they are assigned a username (based on the first 5 characters of their address) and their messages are added directly to the message board. The message board can be viewed on a page hosted by a NomadNet node.
+
+An example message board can be found on the reticulum testnet hosted on the SolarExpress Node `<d16df67bff870a8eaa2af6957c5a2d7d>` and the message board peer `<ad713cd3fedf36cc190f0cb89c4be1ff>`
+
+## How Does It Work?
+The message board page itself is hosted on a NomadNet node, you can place the message_board.mu into the pages directory. You can then run the message_board.py script which provides the peer that the users can send messages to. The two parts are joined together using umsgpack and a flat file system similar to NomadNet and Reticulum and runs in the background.
+
+## How Do I Set It Up?
+* Turn on node hosting in NomadNet
+* Put the `message_board.mu` file into `pages` directory in the config file for `NomadNet`. Edit the file to customise from the default page.
+* Run the `message_board.py` script (`python3 message_board.py` either in a `screen` or as a system service), this script uses `NomadNet` and `RNS` libraries and has no additional libraries that need to be installed. Take a note of the message boards address, it is printed on starting the board, you can then place this address in `message_board.mu` file to make it easier for users to interact the board.

+* This example application was written and contributed by @chengtripp
