 Replace the wildcard (`gip*`) if you want to control the LED of a specific device.
 The modes and the maximum brightness can vary from device to device.
 
+### Pairing mode
+
+The pairing mode of the dongle can be queried via `sysfs`:
+
+```
+cat /sys/bus/usb/drivers/xone-dongle/*/pairing
+```
+
+You can enable (`1`) or disable (`0`) the pairing using the following command:
+
+```
+echo 1 | sudo tee /sys/bus/usb/drivers/xone-dongle/*/pairing
+```
+
 ## Troubleshooting
 
 Uninstall the release version and install a debug build of `xone` (see installation guide).
