It enables programming-course educators to create MCQ (multiple choice question) and assign scores to each question all from the comfort of a Markdown file (.md). You can set passing grades on each course, maximum attempts, and in one quick view see all students who have earned a badge on the course.
Corgi (courses on github) offers a free-for-all buffet-style learning environment by aggregating programming and data science courses from GitHub. You can participate in any course freely, and your attempts will be rewarded with badges. You can bookmark courses for each access, look at others who have completed the course, and you can freely participate in any of the programming courses you find.
