The Open edX Platform is the learning management system and course authoring studio behind edX and many other online learning sites. It lets universities, companies and training providers build courses, deliver them to learners and track progress at any scale.

What it covers

• LMS: the learner-facing site where courses are taken
• Studio: the authoring tool where instructors design courses
• Built mainly with Python and JavaScript and released under the AGPL-3.0 license

The repository you are looking at is the 2U-maintained fork of the project; the wider community also works in the openedx organization on GitHub.
