GitHub:Training is a brand new site from the social coding network:
No matter where you are in the world, we have a mix of both live classes and recorded tutorials that you can access from the comfort of your own computer.
Very neat idea with a handful of free classes I may just audit.
Of course, “git - the simple guide” should spin you up pretty quickly, but knowing Git is only the beginning. Having just dipped my toes into hosting code at GitHub, there is definitely a learning curve to the way the site uses version control, with a slew of power tools waiting to be unleashed.
