Facebook Game Functions

Hey,

So I've googled a fair bit and I'm failing to find a specific set of instructions or just 1 tutorial to rule them all..

I've uploaded a tester game to facebook, So far I've only got just the game, I was wondering if anyone knows of a single tutorial that covers the facebook functions with construct 2 so the publish to peoples walls or invite your friends to play and stuff like that?

And also does anyone know how to add Admob to the game? I followed a tutorial, Made Admob account, Added the Ad number/code to the Admob object in Construct2 and reuploaded it too facebook but nothing happened? I believe I missed a step or two perhaps?

Edit https://www.facebook.com/HydeAndDistrictABC/ This is the game...

Thanks,,
