Git
A save system for your code — like Google Docs version history.
What is Git?
Git tracks every change you make to your code. If something breaks, you can go back to when it worked. When tools mention "push to GitHub" or "commit your changes" — that's Git doing its job.
You don't need to master Git. Four commands cover 90% of what vibe coders need: git add, git commit, git push, and git pull.
In Vibe Coding
Cursor has Git built in — you'll see a source control panel on the left sidebar. Lovable and Bolt can export directly to GitHub, which uses Git under the hood. Even if you never type a git command, your code is being tracked.
Example
For example: You're building a payment feature and it breaks your whole app. With Git, you run git checkout . to undo all your changes and go back to when it was working.
