+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.
