Next, navigate to the root directory of the executable, open your command line, and type:
RandomSteamGameLauncher "YourDisk:/Path/To/Steam/steamapps/libraryfolders.vdf"To blacklist non-game items (e.g., software, modding tools, or invisible games), obtain their AppId from your Steam client (Properties > Updates) and add them to steam_app_blacklist.txt, separated by commas.
