Git
Master Git from your first commit to advanced Git internals. Learn commits, branches, merging, rebasing, remotes, tags, history rewriting, recovery, hooks, and Git’s object model through hands-on problems. Every challenge is verified against a real repository, so you learn how Git actually works by using it, breaking it, and fixing it.
