What is Git?

Learn that Git is a version control system and why it is used.

What is Git?

Git is a distributed version control system that tracks changes in files within software projects. Developers can use Git to inspect previous changes, return to earlier versions, and collaborate on the same project. Git makes managing source code safely and efficiently much easier.

git init
git add index.html
git commit -m "First version"

Git is open source and was created by Linus Torvalds, the developer of Linux.

Why is Git important?

When adding a new feature or fixing a bug in a project, it is important to preserve the previous working version. Git addresses this need by storing changes in records called commits. You can also work on separate branches to develop new features without affecting the main version.

git status
git add .
git commit -m "Add navigation"

Using Git makes it easier to track project history and manage teamwork.

Exercise Write the first Git commands
