Courses are mostly automatically generated in CodeGrade. When creating your assignment in your learning management system, this is automatically added to the right course, or this course is created if it did not exist yet.
Most management in CodeGrade is done on an assignment level, but a couple of things are managed on a course level:
Enrolment and roles
Contacting (all) students
You can change the name of courses. The name may not be empty. As most courses are created from within the learning management system and the name is copied from there too, the name of LTI courses cannot be changed within CodeGrade.
Archiving a course will hide it for students (or more precisely all users that do not have the “See archived courses” permission), and will sort it below all non archived courses. You can still import data from archived courses. Archiving can be reversed without data loss.
