For Global MoodleMoot Online 2020 we designed a workshop for developers to learn how the content bank works and how to implement new content type plugins.
We enjoyed the workshop a lot, and we hope also attendees enjoyed it. So now we are happy to announce the workshop is available for everybody in the community as a course on this site: Developing a basic content-bank plugin.
Please let us know what you think of the course, and if you have any ideas for improvements, by posting in the discussion New workshop for developers: Developing a basic content-bank plugin.
