we can do this separately but I think we should update this page https://grafana.com/developers/plugin-tools/publish-a-plugin/publish-a-plugin either directly here or shortly after.

Maybe remove the whole
"Before you begin" sections and update the intro text.

Otherwise it feels redundant and confusing once we add the "best practices" page.

I've added an extra bullet in the "Before you begin" section that links to this document for now. I think it's worth discussing as part of a separate PR whether this document becomes a sort of pre-requisite guide (and therefore supersedes the "Before you begin" section of the publish page). I hadn't intended for this doc to be a replacement for that initially, and I'm still not sure it makes sense to do that.
