A short introduction to Git, created with one of the Rails Girls events in mind.
It goes through the basic workflow:
1) Cloning the repository (git clone).
2) Working on files.
3) What's the situation? (git status)
4) What exactly have I done? (git diff)
5) I want to share these changes (git add)
6) Double-checking (git diff --cached)
7) Making a commit (git commit)
8) Sharing your changes (git push)
