Git is the single most important tool in modern software development - and also the one developers spend the most time fighting when they don't understand it. This course is built to make sure you never have to Google the same Git command twice.

We start from git init on an empty folder and walk through every workflow you will actually hit in real projects - branching, merging, rebasing, remotes, undoing mistakes, stashing, cherry-picking, history rewriting, and the day-2 troubleshooting questions every team eventually asks. Every chapter is short, every command is tested, and every example uses real files instead of toy foo.txt.

If you are brand new to version control, click Start the course and follow the chapters in order. If you already know the basics, skip straight to the chapter you need - Undoing Changes, Rebasing, and Troubleshooting are the most-bookmarked. The final chapter is a one-page cheat sheet you can keep open as a reference.

What you'll learn

  • Set up Git, create your first repository, and stage / commit / push code confidently
  • Master branching, merging, rebasing, and resolving conflicts the right way
  • Work with remotes - GitHub and GitLab - including upstream tracking, force pushes, and SSH setup
  • Undo every kind of mistake - bad commits, lost branches, deleted files, detached HEAD
  • Use advanced tools - stash, cherry-pick, reflog, filter-branch, squash, tags - like a senior engineer

Prerequisites

  • A workstation with Git installed (Linux, macOS, or Windows with Git Bash)
  • Comfortable on the command line (cd, ls, mkdir, basic file editing)
  • A free GitHub or GitLab account for the remote-workflow chapters
