 # naxalnet
 
-script to setup a batman-advanced network with systemd-networkd
+Naxalnet is an experiment to create an intranet and use it for
+communicating during an internet shutdown. It tries to use
+existing software and tech as much as possible. Currently
+you can only communicate with other peers running the same software.
+
+The name naxal comes from Naxalbari, a village in Darjeeling,
+West Bengal.
+
+<!-- UNCOMMENT WHEN NECESSARY
+
+**Disclaimer**:
+In case you are either 1) a complete idiot; or 2) the prime minister of India;
+or 3) both, please be aware that this project is not affiliated with
+any groups designated as terrorist groups in India.
+
+Using the name Naxal does not imply any form of connection
+with anyone the government collectively calles Urban Naxals (human rights
+activists, lawyers, poets, writers, journalists or anyone else
+advocating the proper implementaion of constitutional or universal rights).
+
+-->
+
+## Requirements
+
+* systemd v248 or more
+* Linux kernel (batman-adv only works on Linux)
+* iwd
+* wifi adapter with ad-hoc support
+
+Any network managers such as NetworkManager should be disabled:
+
+```
+sudo systemctl disable --now NetworkManager
+```
+
+## Installing
+
+Run `make install` to install naxalnet.
+
+Enable the naxalnet service on the device `wlan0`:
+
+```
+sudo systemctl enable naxalnet@wlan0.service
+```
+Now naxalnet will configure a batman interface on every boot.
+
+## TODO
+
+- add support for wireless ap (WiFi hotspot)
+
+Add list of things here.
+
+This project is in pre-alpha stage. Documentation is incomplete.
