Once Smart Courses is installed, you can start creating your own courses. 

When a course is created in a specific space, it is attached to it, and its accessibility will be conditioned by the permissions or restrictions of that same space.

From the "Course catalog", select "New course" to create a course.

ON-PREMISE ONLY: In Smart Courses, if a course is created from the global Course catalog without choosing a target space, the course is global; not attached to a specific space, and can be accessible from the courses menu.
