What is Git?

Git is a version control system used to track changes in code, files, and projects. It helps developers manage different versions of their work efficiently.

You can think of Git as a system that saves the history of your project. If something breaks, you can easily return to a previous version.

Git was created by Linus Torvalds and is widely used in software development.
