 ## Usage
 * Place a copy of `stcs-config.sh.example` next to the game being executed.
 * Edit the file, removing the `.example` and filling out the gamename and the location of the savedata to back up. (It can be a file or folder of savedata)
+    * Note: you may also define a custom configfile path by setting the environment variable `STCS_GAME_CONFIG` prior to executing the wrapper.
 * Prefix any launch command you wish to invoke with `stcs-wrapper.sh`, similar to how you'd load `mangohud`!
