 ## Usage
 
-When booting a GPU set the environment variable `GPUMODE=<driver>` with something
-like `systemd.setenv=GPUMODE=<driver>`. The script will decide how to
-launch sway depending on this variable. Possible values:
-
-- `nvidia`
-- `nouveau`

+Blacklist the module which should not be loaded on boot, the script
+detects if the `nvidia` or `nouveau` driver is loaded and either calls
+`sway-nvidia` or `sway`.
