Adds TOC to architecture.md, getting-started.md, integrations.md and
user-guide.md
Updates README.md to add a notice that the files are best viewed on the
website.
Updates the docs to reflect that it's not a "setup" documention but
rather an installation document.
I've also updated the header of architecture.md to reflect the filename.
