Documentation for including Game Center Integration

Can someone point me in the direction of the documentation for the integration of Game Center support in a game? It seems such a great feature so I am keen to give this a go but I have struggled to find any info apart from one thread which isn’t entirely clear.

I’m integrating Game Center into my game right now and here’s some great documentation I referred to:
http://mobile.tutsplus.com/tutorials/iphone/ios-sdk-game-center-achievements-and-leaderboards-part-1/

This isn’t specific to Corona, but there’s barely anything you really need to do within Corona and that’s covered in a few threads here. The tricky info is all on Apple’s end (which that tutorial covers) and making the OFGameCenter.plist (which is explained on OpenFeint’s website.)
