# What Is Git & GitHub? (Plain English)

The Problem Git Solves

Imagine you are writing a long document. You make changes, then realize you liked the old version better. But you already saved over it. Gone forever.

Now imagine working with a team. Three people edit the same document. Whose changes win? How do you merge everyone is work without losing anything?

Git solves both problems. It is a system that tracks every change you make to your files, lets you go back to any previous version, and helps multiple people work on the same project without stepping on each other.
