 Reticulum is the cryptography-based networking stack for wide-area networks built on readily available hardware. It can operate even with very high latency and extremely low bandwidth. Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption and connectivity, initiator anonymity, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable delivery acknowledgements and more.
 
-The vision of Reticulum is to allow anyone to be their own network operator, and to make it cheap and easy to cover vast areas with a myriad of independent, interconnectable and autonomous networks. Reticulum **is not** *one* network. It is **a tool** for building *thousands of networks*. Networks without kill-switches, surveillance, censorship and control. Networks that can freely interoperate, associate and disassociate with each other, and require no central oversight. Networks for human beings. *Networks for the people*.

 Reticulum is a complete networking stack, and does not rely on IP or higher layers, but it is possible to use IP as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks.

 ## Public Testnet
 If you just want to get started experimenting without building any physical networks, 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 runs the very latest version of Reticulum (often even a short while before it is publicly released). Sometimes experimental versions of Reticulum might be deployed to nodes on the testnet, which means strange behaviour might occur. If none of that scares you, you can join the testnet via eihter TCP or I2P. Just add one of the following interfaces to your Reticulum configuration file:
