Understanding git - even the scary parts
summary
Explains actual git internals: blobs trees commits as storage, how branches are just refs, and why rebasing rewrites commit objects so hashes change. Demonstrates working commands (init, checkout, merge, rebase, log --graph), resolves conflicts live, and compares merge commit vs linear history. Emphasizes recovery tools like reflog and git rerere, recommends experimenting on throwaway branches, avoiding force-push on shared branches, and shows concrete failure-and-restore steps so the comfort comes from reproducible procedures.
