Assume that we want to build a lesson about ancient history. We will call it "Ancient history".

We first need to login as administrator and create the lesson. If we want we can create a new category first that provides a logical organization of lessons.

•From the administrator panel select "Categories" and then "Add category"

•We use "Ancient history" as the name of our new category. Our new category is a main category. By using father categories we could build an arbitrarily big list of nested categories but it is not needed for our example.

•We return to the main administration panel and select "Lessons"

•We use "Ancient history" as the name of our new lesson. We put it under "Ancient history" category and save the new lesson.
