This is a start at a page for diagnosing problems while setting up Grist. Starting to add some diagnostics based on feedback in github issues. We should make Grist installation easier! But when there is a problem it should be easier to diagnose than it is now, and this may help. The page is ugly and doesn't have many diagnostics yet, but we can iterate.
Visit `/boot` on a Grist server for tips on how to use this feature.
