Quick Introduction

Git is version control software. With many people working on software simultaneously, version control is very important. It allows us to:

• Edit a file someone else is editing. (git uses a "diff" to see what you changed, and merge it with other changes.)
• Look back at old code.
• Create branches to test things, and revert back if you change your mind.

It's a very powerful piece of software, and learning to use it helps the whole team work together.
