-Nomad Network
+# 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
+ - 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
 
 ## 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.

-
-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
 
 ## 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.

 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.

 A `*peer`* refers to another Nomad Network client, which will generally be operated by another person. But since Nomad Network is a general LXMF client, it could also be any other LXMF client, program, automated system or machine that can communicate over LXMF.
 
+All peers (and nodes) are identified by their `*address`* (which is, technically speaking, a Reticulum destination hash). An address consist of 32 hexadecimal characters (16 bytes), and looks like this:
+
+`c<e9eafceea9e3664a5c55611c5e8c420a>
+`l
+
+Anyone can choose whatever display name they want, but addresses are always unique, and generated from the unique cryptographic keys of the peer. This is an important point to understand. Since there is not anyone controlling naming or address spaces in Nomad Network, you can easily come across another user with the same display name as you.
+
+Your addresses will always be unique though, and you must always verify that the address you are communicating with is matching the address of the peer you expect to be in the other end.
+
+To make this easier, Nomad Network allows you to mark peers and nodes as either `*trusted`*, `*unknown`* or `*untrusted`*. In this way, you can mark the peers and nodes that you know to be legitimate, and easily spot peers with similar names as unrelated.
+
 >>Announces
 
-An `*announce`* can be sent by any peer on the network, which will notify other peers of its existence, and contains the cryptographic keys that allows other peers to communicate with it.

 Nomad Network uses the term `*conversation`* to signify both direct peer-to-peer messaging threads, and also discussion threads with an arbitrary number of participants that might change over time.
 
-Both things like discussion forums and chat threads can be encapsulated as conversations in Nomad Network. The user interface will indicate the different characteristics a conversation can take, and also what form of transport encryption messages within used.
+Both things like discussion forums and chat threads can be encapsulated as conversations in Nomad Network. The user interface will indicate the different characteristics a conversation can take, and also what form of transport encryption was used for messages within.

+In the `![ Conversations ]`! part of the program you can view and interact with all currently active conversations. You can also edit nickname and trust settings for peers belonging to these conversations here. To edit settings for a peer, select it in the conversation list, and press `!Ctrl-E`!.
+
+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 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 are also integral in allowing forum/discussion threads to exist and propagate 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 online 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.

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 syncronisation of message stores.
+
+To learn how to host your own node, read the `*Hosting a Node`* section of this guide.
+
+'''
+
+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 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.
+
+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 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.
+
+>>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 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.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`!.
+
+>>Files
+
+Like pages, you can place files you want to make available in the `!~/.nomadnetwork/storage/files`! directory. To let a peer download a file, you should create a link to it in one of your pages.
+
+>>Links and URLs
+
+Links to pages and resources in Nomad Network use a simple URL format. Here is an example:
+
+`!18176ffddcc8cce1ddf8e3f72068f4a6:/page/index.mu`!
+
+The first part is the 10 byte destination address of the node (represented as readable hexadecimal), followed by the `!:`! character. Everything after the `!:`! represents the request path.
+
+By convention, Nomad Network nodes maps all hosted pages under the `!/page`! path, and all hosted files under the `!/file`! path. You can create as many subdirectories for pages and files as you please, and they will be automatically mapped to corresponding request paths.
+
+You can omit the destination address of the node, if you are reffering to a local page or file. You must still keep the `!:`! character. In such a case, the URL to a page could look like this:
+
+`!:/page/other_page.mu`!
+
+The URL to a local file could look like this:
+
+`!:/file/document.pdf`!
+
+Links can be inserted into micron documents. See the `*Markup`* section of this guide for info on how to do so.

+TOPIC_FIRST_RUN = '''>First Time Information
+
+Hi there. This first run message will only appear once. It contains a few pointers on getting started with Nomad Network, and getting the most out of the program.
+
+You're currently located in the guide section of the program. I'm sorry I had to drag you here by force, but it will only happen this one time, I promise. If you ever get lost, return here and peruse the list of topics you see on the left. I will do my best to fill it with answers to mostly anything about Nomad Network.
+
+To get the most out of Nomad Network, you will need a terminal that supports UTF-8 and at least 256 colors, ideally true-color. If your terminal supports true-color, you can go to the `![ Config ]`! menu item, launch the editor and change the configuration.
+
+It is recommended to use a terminal size of at least 122x32. Nomad Network will work with smaller terminal sizes, but the interface might feel a bit cramped.
+
+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.
+
+Nomad Network expects that you are already connected to some form of Reticulum network. That could be as simple as the default one that Reticulum auto-generates on your local ethernet/WiFi network, or something much more complex. This short guide won't go into any details on building networks, but you will find other entries in the guide that deal with network setup and configuration.
+
+At least, if Nomad Network launches, it means that it is connected to a running Reticulum instance, that should in turn be connected to `*something`*, which should get you started.
+
+For more some more information, you can also read the `*Introduction`* section of this guide.
+
+Now go out there and explore. This is still early days. See what you can find and create.

+'''
+
+TOPIC_CONFIG = '''>Configuration Options
+
+To change the configuration of Nomad Network, you must edit the configuration file. If you did not manually specify a config path when you started the program, Nomad Net will look for a configuration in the folllowing directories:
+
+  `!/etc/nomadnetwork`!
+  `!~/.config/nomadnetwork`!
+  `!~/.nomadnetwork`!
+
+If no existing configuration file is found, one will be created at `!~/.nomadnetwork/config`! by default. The default configuration file contains comments on all the different configuration options present, and explains their possible settings.
+
+You can open the configuration file in any text-editor, and change the options. You can also use the editor built in to this program, under the `![ Config ]`! menu item. If the built-in editor does not gain focus, and your navigation keys are not working, try hitting enter or space, which should focus the editor and let you navigate the text.
+
+For reference, all the configuration options are listed and explained here as well. The configuration is divided into different sections, each with their own options.
+

+<
+
+>>>
+`!print_command = lp -d PRINTER_NAME -o cpi=16 -o lpi=8`!
+>>>>
+Specifies the command that Nomad Network uses to print the message. Defaults to "lp". The above example works well for small thermal-roll printers.
+<
+
+>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 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, 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.
+
+For future reference, you can download the Reticulum Manual in PDF format here:
+
+`c`_https://github.com/markqvist/Reticulum/raw/master/docs/Reticulum%20Manual.pdf`_
+`l
+
+It might be nice to keep that handy when you are not connected to the Internet, as it is full of information and examples that are also very relevant to Nomad Network.
+
+>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 Zurich]]
+  type = TCPClientInterface
+  interface_enabled = yes
+  outgoing = True
+  target_host = zurich.connect.reticulum.network
+  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`!.

+Links to pages, files or other resources can be created with the \\`[ tag, which should always be terminated with a closing ]. You can create links with and without labels, it is up to you to control the formatting of links with other tags. Although not strictly necessary, it is good practice to at least format links with underlining.

+
+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

-TOPIC_FIRST_RUN = '''>First Time Information
-
-Hi there. This first run message will only appear once. It contains a few pointers on getting started with Nomad Network, and getting the most out of the program.
-
-You're currently located in the guide section of the program. I'm sorry I had to drag you here by force, but it will only happen this one time, I promise. If you ever get lost, return here and peruse the list of topics you see on the left. I will do my best to fill it with answers to mostly anything about Nomad Network.
-
-To get the most out of Nomad Network, you will need a terminal that supports UTF-8 and at least 256 colors, ideally true-color.
-
-By default, Nomad Network starts in low-color mode. It does this for the sake of compatibility, but it does look rather ugly. If your terminal supports true-color or just 256 colors, you should go to the `![ Config ]`! menu item, launch the editor and change the configuration to use a high-color mode.
-
-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.
-
-Nomad Network expects that you are already connected to some form of Reticulum network. That could be as simple as the default UDP-based demo interface on your local ethernet network. This short guide won't go into any details on building, but you will find other entries in the guide that deal with network setup and configuration.
-
-At least, if Nomad Network launches, it means that it is connected to a running Reticulum instance, that should in turn be connected to `*something`*, which should get you started.
-
-For more some more information, you can also read the `*Introduction`* section of this guide.
-
-Now go out there and explore. This is still early days. See what you can find and create.
