The document provides an introduction to source control and GitHub. It explains that source control allows multiple people to work on a project separately and combine changes later using Git. GitHub is a hosting service for Git repositories that offers features like issue tracking, pull requests, and editing files directly in the browser. It also provides resources for getting started with Git and GitHub including Gist for sharing code snippets and the Student Developer Pack for students.

• Experiment without breaking working code
