A few years ago a few contributors from Open edX, Telecom Paris, OpenStack and Wikipedia created the Open Source Masterclass. It is an onboarding course to learn how to contribute upstream - the idea was to build one good course, shared between different projects like Open edX who need to teach this, instead of each project redeveloping their own course.
And now, the course has reached v1! We would really appreciate feedback, ideas, bug reports. Whether you are already a contributor or want to become one, have a look
