The Git & GitHub Bootcamp

Colt Steele goes from the essentials through branching, merging and collaboration workflows, and into the material most courses skip — interactive rebase, Git's internal object model, and reflogs for rescuing lost commits. With over 200,000 students it is one of the most-taken Git courses on Udemy, and that depth is useful even if you already know the basics.

That said, if you already use Git confidently, or you only need the basic commands, a shorter free tutorial will do instead — this goes deeper than a casual user needs. On price, wait for a Udemy sale.

Organized into four units (Git Essentials, Next Level Git, GitHub & Collaboration, The Tricky Bits), this course goes well beyond basic add/commit/push: it covers diffing, stashing, undoing changes (checkout, restore, reset, revert), collaboration workflows (fork & clone, pull requests), and the genuinely advanced material most Git courses skip — interactive rebase, Git internals (blobs, trees, hashing), reflogs for rescuing lost commits, and writing custom Git aliases.
