Hereby, we are making a start on this refactoring process.

• Scale: Refurbish section, and absorb relevant tutorials from community forum #150

NB: We will share a few patches as we go, that can be used as blueprints to learn how the refactoring works. Because it's all Markdown, it works pretty straight-forward on the first iteration when copying content verbatim.
