Arranging topics in a hierarchy is not sufficient. Instead we are creating a graph of topics and levels with multiple types of edges: "is-a-subtopic-of", "is-a-prerequisite-of" etc. If you are an expert or educator in some domain, you can contribute to this project via our GitHub repository.</p>

More on this will be revealed soon.</p>
