THIS IS A BETA RELEASE! This has been tested on several computers but there is the potential for errors with different configurations!
To use, simply download the installer, run it, and then start the program after it finishes installing. When it starts it will try to find your GTA5 folder. If it can't, it will ask you to find it.
Then you can check for conflicts using the interface, and once you're happy with your files, you can display a printable key mapping for easier lookup.
