Restore landing page

[ajschmidt8]

This PR restores the static landing page functionality (which is useful as a health check) that was lost during the v1 to v2 transition.

It also removes a dead link from the landing page.

Note: To avoid merge conflicts, I've based these changes on #91. That PR should be merged first.
