GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its features. Unlike Git, which is strictly a command-line tool, GitHub provides an additional web-based graphical interface and desktop as well as mobile integration. It also provides access control and several collaboration features such as code reviews and integration with test suites.
Queen Mary University of London uses GitHub Enterprise. GitHub Enterprise offers the same functionality as the public GitHub.com offering but all data is hosted within QMUL, authenticating against QMUL servers. All QMUL currently enrolled students, student-facing faculty, and anyone performing academic non-profit research can use it free of charge by going to github.qmul.ac.uk
