+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.

 ## 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

 ```
 
+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:
 
- - `464ddc8cd323648ef919a638923b4916` Dublin Hub Testnet Node
+ - `abb3ebcd03cb2388a838e70c001291f9` Dublin Hub Testnet Node
- - `5cda089fc42675bdd904c6d06db87d49` Frankfurt 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.

 ## 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.

+# 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.

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

+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.

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.
+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 together with hyperlinks, that can also link to pages (or other resources) on other nodes.
 
 To add pages to your node, place micron files in the `*pages`* directory of your Nomad Network programs `*storage`* directory. By default, the path to this will be `!~/.nomadnetwork/storage/pages`!. You should probably create the file `!index.mu`! first, as this is the page that will get served by default to a connecting peer.
 
 You can control how long a peer will cache your pages by including the cache header in a page. To do so, the first line of your page must start with `!#!c=X`!, where `!X`! is the cache time in seconds. To tell the peer to always load the page from your node, and never cache it, set the cache time to zero. You should only do this if there is a real need, for example if your page displays dynamic content that `*must`* be updated at every page view. The default caching time is 12 hours. In most cases, you should not need to include the cache control header in your pages.
 
+>> Dynamic Pages
+
 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`!.
 
+Data from fields and link variables will be passed to these scipts or programs as environment variables, and can simply be read by any method for acessing such.
+
+In the `!examples`! directory, you can find various small examples for the use of this feature. The currently included examples are:
+
+ - A messageboard that receives messages over LXMF, contributed by trippcheng
+ - A simple demonstration on how to create fields and read entered data in node-side scripts
+
+By default, you can find the examples in `!~/.nomadnetwork/examples`!. If you build something neat, that you feel would fit here, you are more than welcome to contribute it.

 >>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".
+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.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:

+>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:
 
 >>

 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:

 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.

+>Fields & Requests
+
+Nomad Network let's you use simple input fields for submitting data to node-side applications. Submitted data, along with other session variables will be available to the node-side script / program as environment variables.
+
+>>Request Links
+
+Links can contain request variables and a list of fields to submit to the node-side application. You can include all fields on the page, only specific ones, and any number of request variables. To simply submit all fields on a page to a specified node-side page, create a link like this:
+
+`Faaa
+`=
+`[Submit Fields`:/page/fields.mu`*]
+`=
+``
+
+Note the `!*`! following the extra `!\``! at the end of the path. This `!*`! denotes `*all fields`*. You can also specify a list of fields to include:
+
+`Faaa
+`=
+`[Submit Fields`:/page/fields.mu`username|auth_token]
+`=
+``
+
+If you want to include pre-set variables, you can do it like this:
+
+`Faaa
+`=
+`[Query the System`:/page/fields.mu`username|auth_token|action=view|amount=64]
+`=
+``
+
+>> Fields
+
+Here's an example of creating a field. We'll create a field named `!user_input`! and fill it with the text `!Pre-defined data`!. Note that we are using background color tags to make the field more visible to the user:
+
+`Faaa
+`=
+A simple input field: `B444`<user_input`Pre-defined data>`b
+`=
+``
+
+You must always set a field `*name`*, but you can of course omit the pre-defined value of the field:
+
+`Faaa
+`=
+An empty input field: `B444`<demo_empty`>`b
+`=
+``
+
+You can set the size of the field like this:
+
+`Faaa
+`=
+A sized input field:  `B444`<16|with_size`>`b
+`=
+``
+
+It is possible to mask fields, for example for use with passwords and similar:
+
+`Faaa
+`=
+A masked input field: `B444`<!|masked_demo`hidden text>`b
+`=
+``
+
+And you can of course control all parameters at the same time:
+
+`Faaa
+`=
+Full control: `B444`<!32|all_options`hidden text>`b
+`=
+``
+
+Collecting the above markup produces the following output:
+
+`Faaa`B333
+
+A simple input field: `B444`<user_input`Pre-defined data>`B333
+
+An empty input field: `B444`<demo_empty`>`B333
+
+A sized input field:  `B444`<16|with_size`>`B333
