The first thing you will want to do is to set up general options that control the appearance and structure of your course.
You'll need to select one of Moodle's two ways of organizing the sequence of material in your course:
By week, if you have a fairly strict chronological sequence.
By topic, if students need to cover material in sequence but without reference to specific dates.
Decide how you want to organize the material before proceeding to the next section.
