Git Basics

Git tracks changes to your code over time. Every change is saved as a commit.

Core workflow:

bash git init # Start tracking a folder git status # See what's changed git add file.py # Stage a file for commit git add . # Stage all changes git commit -m "msg" # Save a snapshot git log # See history

Three areas:

• 1. Working directory — your files as you edit them
• 2. Staging area — files ready to be committed
• 3. Repository — committed snapshots

A good commit message is short (50 chars) and explains *why*, not just *what*.
