Nomad Network is build on LXMF and 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 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. 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 best time to have an influence on the direction of the development of Nomad Network. To do so, join the discussion on the Nomad Network project on GitHub. >Concepts and Terminology The following section will briefly introduce various concepts and terms used in the program. >>Peer 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. >>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. In the `![ Network ]`! section of the program, you can monitor announces on the network, initiate conversations with announced peers, and announce your own peer on the network. >>Conversations 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. 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 here. >>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. 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. ''' TOPIC_CONVERSATIONS = '''Conversations ============= Conversations in Nomad Network ''' TOPIC_MARKUP = '''>Outputting Formatted Text >>>>>>>>>>>>>>> -\u223f < `c`!Hello!`! This is output from `*micron`* Micron generates formatted text for your terminal `a >>>>>>>>>>>>>>> -\u223f < Nomad Network supports a simple and functional markup language called `*micron`*. If you are familiar with `*markdown`* or `*HTML`*, you will feel right at home writing pages with micron. With micron you can easily create structured documents and pages with formatting, colors, glyphs and icons, ideal for display in terminals. >>Recommendations and Requirements While micron can output formatted text to even the most basic terminal, there's a few capabilities your terminal `*must`* support to display micron output correctly, and some that, while not strictly necessary, make the experience a lot better. Formatting such as `_underline`_, `!bold`! or `*italics`* will be displayed if your terminal supports it. If you are having trouble getting micron output to display correctly, try using `*gnome-terminal`*, which should work with all formatting options out of the box. Most other terminals will work fine as well, but you might have to change some settings to get certain formatting to display correctly. >>>Encoding All micron sources are intepreted as UTF-8, and micron assumes it can output UTF-8 characters to the terminal. If your terminal does not support UTF-8, output will be faulty. >>>Colors Shading and coloring text and backgrounds is integral to micron output, and while micron will attempt to gracefully degrade output even to 1-bit terminals, you will get the best output with terminals supporting at least 256 colors. True-color support is recommended. >>>Terminal Font While any unicode capable font can be used with micron, it's highly recommended to use a `*"Nerd Font"`* (see https://www.nerdfonts.com/), which will add a lot of extra glyphs and icons to your output. > A Few Demo Outputs `F222`Bddd `cWith micron, you can control layout and presentation `a `` `B33f You can change background ... `` `B393 `r`F320... and foreground colors`f `a `b If you want to make a break, horizontal dividers can be inserted. They can be plain, like the one below this text, or you can style them with unicode characters and glyphs, like the wavy divider in the beginning of this document. - `cText can be `_underlined`_, `!bold`! or `*italic`*. You can also `_`*`!`B5d5`F222combine`f`b`_ `_`Ff00f`Ff80o`Ffd0r`F9f0m`F0f2a`F0fdt`F07ft`F43fi`F70fn`Fe0fg`` for some fabulous effects. `a >>>Sections and Headings You can define an arbitrary number of sections and sub sections, each with their own named headings. Text inside sections will be automatically indented. - If you place a divider inside a section, it will adhere to the section indents. >>>>> If no heading text is defined, the section will appear as a sub-section without a header. This can be useful for creating indented blocks of text, like this one. >Micron tags Tags are used to format text with micron. Some tags can appear anywhere in text, and some must appear at the beginning of a line. If you need to write text that contains a sequence that would be interpreted as a tag, you can escape it with the character \\. In the following sections, the different tags will be introduced. Any styling set within micron can be reset to the default style by using the special \\`\\` tag anywhere in the markup, which will immediately remove any formatting previously specified. >>Alignment To control text alignment use the tag \\`c to center text, \\`l to left-align, \\`r to right-align, and \\`a to return to the default alignment of the document. Alignment tags must appear at the beginning of a line. Here is an example: `Faaa `= `cThis line will be centered. So will this. `aThe alignment has now been returned to default. `rThis will be aligned to the right `` `= `` The above markup produces the following output: `Faaa`B333 `cThis line will be centered. So will this. `aThe alignment has now been returned to default. `rThis will be aligned to the right `` >>Formatting Text can be formatted as `!bold`! by using the \\`! tag, `_underline`_ by using the \\`_ tag and `*italic`* by using the \\`* tag. Here's an example of formatting text: `Faaa `= We shall soon see `!bold`! paragraphs of text decorated with `_underlines`_ and `*italics`*. Some even dare `!`*`_combine`` them! `= `` The above markup produces the following output: `Faaa`B333 We shall soon see `!bold`! paragraphs of text decorated with `_underlines`_ and `*italics`*. Some even dare `!`*`_combine`!`*`_ them! `` >>Sections To create sections and subsections, use the > tag. This tag must be placed at the beginning of a line. To specify a sub-section of any level, use any number of > tags. If text is placed after a > tag, it will be used as a heading. Here is an example of sections: `Faaa `= >High Level Stuff This is a section. It contains this text. >>Another Level This is a sub section. >>>Going deeper A sub sub section. We could continue, but you get the point. >>>> Wait! It's worth noting that we can also create sections without headings. They look like this. `= `` The above markup produces the following output: `Faaa`B333 >High Level Stuff This is a section. It contains this text. >>Another Level This is a sub section. >>>Going deeper A sub sub section. We could continue, but you get the point. >>>> Wait! It's worth noting that we can also create sections without headings. They look like this. `` >Colors Foreground colors can be specified with the \\`F tag, followed by three hexadecimal characters. To return to the default foreground color, use the \\`f tag. Background color is specified in the same way, but by using the \\`B and \\`b tags. Here's a few examples: `Faaa `= You can use `B5d5`F222 color `f`b `Ff00f`Ff80o`Ffd0r`F9f0m`F0f2a`F0fdt`F07ft`F43fi`F70fn`Fe0fg`f for some fabulous effects. `= `` The above markup produces the following output: `Faaa`B333 You can use `B5d5`F222 color `f`B333 `Ff00f`Ff80o`Ffd0r`F9f0m`F0f2a`F0fdt`F07ft`F43fi`F70fn`Fe0fg`f for some fabulous effects. `` >Literals To display literal content, for example source-code, or blocks of text that should not be interpreted by micron, you can use literal blocks, specified by the \\`= tag.

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, or as advanced as some elaborate hybrid RF and free-space optical laser network. This short guide won't go into any details on that, 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. Now go out there and explore. This is still early days. See what you can find and create. >>>>>>>>>>>>>>> -\u223f < ''' TOPIC_LICENSES = '''>Thanks, Acknowledgements and Licenses This program uses various other software components, without which Nomad Network would not have been possible.
