# Git Fundamentals
Git is the version control system used by virtually every professional software team. If you are learning to code with AI, Git is the skill that transforms you from "someone who writes code" to "someone who ships software."
The Mental Model
Forget memorizing commands for a moment. Git manages three zones:
- 1.Working Directory — Your actual files on disk. This is where you write code.
- 2.Staging Area — A "loading dock" where you prepare changes for a commit. You decide exactly what goes in.
- 3.Commit History — A permanent timeline of snapshots. Every commit is a save point.
The flow: Edit files → Stage changes → Commit snapshot → Repeat.
Essential Commands
# Initialize a new Git repository

# Check what's changed
