+# Nomad Network - 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)
 
-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 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.
 
-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.
+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.

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. Since Nomad Network uses Reticulum, it is efficient enough to run even over *extremely* low-bandwidth medium, and has been succesfully used over 300bps radio links.
+
+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.

  - An easy to use and bandwidth efficient markup language for writing pages
  - Page caching in browser
 
-## 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:
 
 ```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
 ```
 
-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.
+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:
 
-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.
+```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 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.

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

 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.

 TOPIC_HOSTING = '''>Hosting a Node
 
-To host a node on the network, you must enable it in the configuration file, by setting `*enable_node`* directive to `*yes`*. You should also configure the other node-related parameters such as the node name and announce interval settings. Once node hosting has been enabled in the configuration, Nomad Network will start hosting your node as soon as the program is lauched, and other peers on the network will be able to connect and interact with content on your node.

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 will automatically participate in a distributed message store that allows users to exchange messages, even when they are not connected to the network at the same time.
+
+When Nomad Network is configured to host a node, by default 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.
+
+`!However`!, 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:
+
+ - Immediately break peering with a node by pressing `!Ctrl-X`!
+ - 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.
+
 >>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.
+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.
 
-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`!.
+>> Dynamic Pages
+
+You can use a preprocessor such as PHP, bash, Python (or whatever you prefer) to generate dynamic pages and fully interactive applications running over Nomad Network. 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 accessing 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.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
+`=
+d454bcdac0e64fb68ba8e267543ae110
+2b9ff3fb5902c9ca5ff97bdfb239ef50
+7106d5abbc7208bfb171f2dd84b36490
+`=
+``
+
+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`!.

 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.

+>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 Dublin]]
   type = TCPClientInterface
-  interface_enabled = yes
-  outgoing = True
-  target_host = frankfurt.rns.unsigned.io
+  enabled = yes
+  target_host = dublin.connect.reticulum.network
   target_port = 4965
+<
 
+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`!.

+>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
+
+A masked input field: `B444`<!|masked_demo`hidden text>`B333
+
+Full control: `B444`<!32|all_options`hidden text>`B333
+`b
+>>> Checkboxes
+
+In addition to text fields, Checkboxes are another way of submitting data. They allow the user to make a single selection or select multiple options. 
+
+`Faaa
+`=
+`<?|field_name|value`>`b Label Text`
+`=
+When the checkbox is checked, it's field will be set to the provided value. If there are multiple checkboxes that share the same field name, the checked values will be concatenated when they are sent to the node by a comma.
+``
+
+`B444`<?|sign_up|1`>`b Sign me up`
+
+You can also pre-check both checkboxes and radio groups by appending a |* after the field value.
+
+`B444`<?|checkbox|1|*`>`b Pre-checked checkbox`
+
+>>> Radio groups
+
+Radio groups are another input that lets the user chose from a set of options. Unlike checkboxes, radio buttons with the same field name are mutually exclusive.
+
+Example:
+
+`=
+`B900`<^|color|Red`>`b  Red
+
+`B090`<^|color|Green`>`b Green
+
+`B009`<^|color|Blue`>`b Blue
+`=
+
+will render:
+
+`B900`<^|color|Red`>`b  Red
+
+`B090`<^|color|Green`>`b Green
+
+`B009`<^|color|Blue`>`b Blue
+
+In this example, when the data is submitted, `B444` field_color`b will be set to whichever value from the list was selected.
+
+``
