@jehlers Is there anything left on this doc we can add into this task to get this to a "done" state for a while? https://docs.google.com/document/d/1i4Vs6pdS-lDLNdnbYC6CQl8MJ1MwPLGdzKTQDLiGhhw/edit#

We don't have any info about the Notice & Comment pilot on eregs.io currently.

@Journerdism this task is focused on just the guidelines. Maybe we should talk as a group about the other elements? I know @cmc333333 has a PR waiting for the governance section.
