Git is a version control system for tracking changes to code. Initialize a folder as a git repository to save snapshots of your work, branch to experiment safely, and synchronize with teammates via remotes.
Every change is recorded as a commit, a snapshot of your project at a point in time. You can view history, revert to old commits, and understand who changed what and why. Git is decentralized—each person gets a full copy of the repository's history, so you work offline and sync with others when ready.
$ git init # create a repository $ git add . # stage changes $ git commit -m "message" # create a commit $ git push origin main # push to remote
On a multi-person project, branching lets each developer work in isolation without conflicts. Create a branch, make changes, and merge back when ready.
