Discovery, Documentation, Adoption, Migration Strategy
If you can, explain how users will be able to use this and possibly write out a version the docs (if applicable).
Maybe a screenshot or design?
If my doc is not public, I need to sign in to see it.
If my doc is public and edit is available to anyone with the link, then anyone can edit it.
