For those of you who are interested to alternative to Github, I would suggest Bitbucket. While I prefer the interface to Github over Bitbucket, Bitbucket does allow you to have free private repositories.
You’ll notice I opted to teach everyone using an application vs command line. Mostly because I feel command line can be kinda intimidating for someone just learning version control. A future comic will be covering using command line for Git. but we’ll do some coding first!
If you’re interested in learning more about Git, they do have a manual, and Code School has a fun intro course that will help you practice.
