git is a distributed version control system created by [[Linus Torvalds]] (also creator of [[Linux]]).

I think of it as "save points with history + branching" for code.

Core workflow:
- `git add` to stage changes
- `git commit` to capture a snapshot
- `git branch` / `git switch` to work in parallel lines of development
- `git merge` or rebase to bring work back together

Platforms like [[github]] host git repositories and add collaboration workflows around pull requests, issues, and CI.
