Render Engine's components build off of one another.
At the base level there is a Page, it is just that a single
entity of HTML and metadata goodness.
Sometimes a lot of pages will have a lot in common or belong to
a group. We call these Collections. Collections
can have any number of the same, or different attributes. Oh and
your collections can even have collections...🤯
All of these pages we build need a home. We call that a
Site. A site serves as a container for your pages
controlling it's structure and how pages are built.
Last but not least is the Engine. And engine is what is doing
the work building out your pages from the data and templates that
you have provided it. How do you start that engine? Simple.
