Completion criteria:

Add links to more detailed sections in the Archive such as https://connectopensource.atlassian.net/wiki/spaces/CONNECTWIKI/pages/8585399/Patient+Discovery. Notice all the sub-pages under that PD page. We don't need to move all those sub-pages over but we should provide a way to navigate to those pages from the new PD page.

All pages reviewed
