So far, we’ve learned how to work on Git as a single user. Git also offers a suite of collaboration tools to make working with others on a project easier.

Imagine that you’re a science teacher, developing some quizzes with Sally, another teacher in the school. You are using Git to manage the project.

In order to collaborate, you and Sally need:

• A complete replica of the project on your own computers
• A way to keep track of and review each other’s work
• Access to a definitive project version

You can accomplish all of this by using remotes. A remote is a shared Git repository that allows multiple collaborators to work on the same Git project from different locations. Collaborators work on the project independently, and merge changes together when they are ready to do so.
