+## How to use
 
 You need more than one computer running for the connection to work.
-Start the naxalnet service:
+
+### Communicate between peers
+
+Connect a wifi adapter to all the computers you intend to run
+naxalnet.
+Start the naxalnet service on all of them:
 
 ```sh
 sudo systemctl start naxalnet.service
 ```
 
+To test if it works, run `ip addr` to find out your address.
+Note the `inet` or `inet6` address of `bridge0`. Ping the address
+from another computer (example: `ping 169.254.62.90`) to find out
+if it is online. Press Ctrl-C to stop.
+
+### Getting internet access
+
+Connect an ethernet to any of the peers and start naxalnet.
+Now all the peers should be able to connect after renewing
+their DHCP connection (`sudo networkctl renew bridge0`).
+
+### Tethering via WiFi AP
+
+Connect two wifi adapters on a device and start naxalnet.
+Now an ap will be created on one of the devices with
+SSID `NaxalNet` and password `naxalnet256`.
+If you had set up internet access on one of the peers, internet
+can be accessed from the AP.
+
+### Running at boot
+
 Starting the service will stop `NetworkManager.service` and
 `wpa_supplicant.service` if it is running. If you start either of these
 services after naxalnet is started, systemd will stop naxalnet.
