💡 What is Git?

Git is a version control system (VCS). It helps you:

  • Track every change in your code
  • Revert to earlier versions if something breaks
  • Work on the same files with your partner without conflicts

Think of it like a time machine for your project with superpowers for teamwork.

🛠️ Installing Git

Install Git on your device:

🔧 Setting Up Git (One Time)

Open Terminal or Command Prompt and run:

git config --global user.name "Your Name"
git config --global user.email "your@email.com"

Option 1: Start a New Project

mkdir my-project
cd my-project
git init

Option 2: Clone an Existing Project
