Content Management Rendering Content With Elements Lights, Camera, Action

Sections

Sections are where the magic happens. They have two big jobs apart from supplying a slug property for a segment of a URL. 

One of those jobs is organizing content - like folders on a filesystem. 

Most importantly, sections are where you're going to bind your code, by way of selecting a Section Renderer  which itself is an Element inside of a Bundle.

Elements are the muscle and bones of the render layer. They're the magical piece that lets you interpret the request, pull relevant data, merge APIs and mark them up with a template. More on them in a bit.   

Domains

Domains are a special type of section which can't be moved from the root of the tree.
