Creating courses is reserved to the super-administrators (See Configuration reference). Course administrators are then able to configure the course by themselves.
Demonstration tasks are made available for download on the INGInious-demo-tasks repository. They can also be downloaded and installed automatically via the inginious-install script. You can also download courses examples on the marketplace page which allows to easily import courses files. The list of these open source courses is also available on the INGInious-course repository
Using the webapp :
As a super-administrator, go to the bottom of the My course list page and enter a new course id, for instance
demo,and click on Create new course. A newly created hidden course named demo appears on the list.
Click on that course, and then on Course administration in the sidebar to change the course parameters, add course administrators and tasks.
