CREATE: reformat into tables and add section links

This just fixes a particular section I happened to be looking at.

My main goal was to add useful internal links, since the section numbers (e.g. "see 5.1.4") don't match the new mdbook section numbers, making it ~impossible to navigate. (I wonder if there's a blanket fix we could do though to make the mdbook section numbers line up with the old ones as a stop gap?)

To add real links I needed to migrate out of pre text blocks, so I made tables. Headings are mandatory in markdown tables, so I added those too.
