All Help Center knowledge base content is organized in the following tree structure:

Home > Categories > Sections > Articles

Each article must be a child of a section, and each section must be child of a category. You cannot have orphan articles or sections.

The Help Center must have at least one category. Today, the edX Help Center has one category, named FAQs. Categories are the top-level organizing containers of the Help Center. You can use categories as content portals for different products or services, or for different kinds of content. For example, you can create one category for partners and one category for learners. In the future, we've discussed creating categories for learners, course teams, and enterprise/integrations. 

If you have only one category in your Help Center (as we do today), then the category itself is hidden to end-users, and they see only the sections that are in your Help Center.

The new edX Help Center will have six main categories, containing a number of sections, which will correspond to current edX Learner Guide chapters. These sections will consist of as many articles as needed to cover the relevant content.
