David Baumgold, Open edX Developer Advocate, gives you the lowdown on Open edX.
You've heard that edX is open source, but what does that actually mean? We'll talk about what open source is, how it works, and how you can join the community of people around the world helping to build and improve edX together. If you want to learn about implementing custom features for edX, or how to use custom features that other people have implemented, this is the talk for you! Visit the Open edX community at Open edX.
