+By default, the `komorebi.ahk` file should be located in the `$Env:USERPROFILE`
+directory, however, if `$Env:KOMOREBI_CONFIG_HOME` is set, it should be located
+there.
+
+Once the file is in place, you can stop komorebi and whkd by running `komorebic stop --whkd`,
+and then start komorebi with Autohotkey by running `komorebic start --ahk`.
