[Basic] Installing and using RetroArch for OSX 10.7.5?

Hello,

I understand that this is a very basic question but i’ve got to ask it:

How do I use RetroArch? There wasn’t any documentation so I didn’t have anything to really read. I’ve dragged RetroArch to my Applications folder, ran it and it keeps prompting me with a message saying that there are no Cores loaded. I’ve downloaded the cores but the instructions that it gives (Go -> Cores Directory) does nothing so I can’t point it to the directory in which i’ve got the Cores at for it to load. I’ve tried going into RetroArch’s preferences and setting up the “Core Options” directory manually there, but it doesn’t seem to be working there, though I suspect that’s something a bit different from what the original prompt is asking me for.

Can anyone help me out and point me in the right direction into getting this set up and working? Or at least point me to some documentation/readme’s to get a better understanding.

Thanks!
