Keep all WIKI documentation in /docs

I think this would just be a sub-module for the wiki?

Idea 1

• [ ] Move all documentation to wiki
• [ ] Maybe (if we can) make wiki composer installable
• [ ] Commit the docs to the repo if we can
• [ ] Add documentation to update docs with composer update

I think I have enough README's in the code that leads to the Wiki.
