@gwossum Just FYI, I cut a new influxdb-enterprise-1.13.0 branch to act as the base branch for this to merge into. That way we can review and merge everything into a release branch and ship it all at once when the release is ready.

Approved with some syntax suggestions on notes and warnings. We've moved to using GitHub-style alert blocks rather than the shortcode notes and warnings. We still support those for backwards compatibility, but new updates should use the new alert blocks.
