How to quickly set up Git for teams using Xcode?
I have an Xcode project folder on my Mac HD. Snow Leopard. The GitX GUI expects that I already have an Git repository. So I guess since I have GitX installed, I also have Git, and now I need to be cool and intelligent and know what to hack into the Terminal. But what? Is there any tutorial that explains this in minutes, not hours or even days?
