Introduction to Github

Github is a free and open-source version control system, that helps you keep track of changes to files in a filesystem/repository over time. It has been an industry standard for a while now. Git comes with the git-shell which has a set of nifty commands that can help you do all sorts of things on your repositories.

Github is a service that hosts your repositories online and lets you collaborate with others through it. You can use Github through the browser or the git-shell on your pc.
