+hardware-specific and kernel-specific quirks.  There is also the
+@command{ratbagctl} command line interface for configuring devices.
+
+libratbag currently supports devices from Logitech, Etekcity, GSkill, Roccat,
+Steelseries.
+
+The ratbagd dbus service can be enabled by adding the following service to
+your operating-system definition:
+(simple-service 'ratbagd dbus-root-service-type (list libratbag))
