Introduction to Git

Git is a distributed version control system created by Linus Torvalds in 2005.

Why Git?

• Track every change to your codebase
• Collaborate without overwriting each other's work
• Roll back mistakes instantly
• Branch freely, merge confidently

Core concepts

• Repository: the database of all your project history
• Commit: a snapshot of your files at a point in time
• Branch: a pointer to a commit
• Working tree: your current files on disk

Your first repo

git init my-project
cd my-project
echo "# Hello" > README.md
git add README.md
git commit -m "Initial commit"

Congratulations — you just created your first Git repo!
