 Rusticl
 =======
 
+Enabling
+--------
+
+In order to use Rusticl on any platform the environment variable
+:envvar:`RUSTICL_ENABLE` has to be used. Rusticl does not advertise devices
+for any driver by default yet as doing so can impact system stability until
+remaining core issues are ironed out.
