How to use it? Lack of instructions

[jalbam]

Hello,

This project looks interesting but I was wondering how to use it as I could not find any instructions detailing the usage steps.

I wanted to test it on some old systems with old browsers just to check whether it could be used in one of my projects. I can understand it needs the "gamepad-shim.swf" file found in the "binary" folder of the project but what is the main JavaScript file?

There are many JavaScript files found in the "source/js/" file but none seems to be compatible with IE9 or other old browsers.

Thank you very much in advance.

Best regards,
Joan
