 Edit or add.  That's the primary instruction.  You can edit directly on [gitlab.com/agaric/documentation](https://gitlab.com/agaric/documentation) (for example, the edit link on this page takes you to [gitlab.com/agaric/documentation/blob/master/documentation.md](https://gitlab.com/agaric/documentation/blob/master/documentation.md)).  If you aren't a member of Agaric, GitLab will helpfully offer to fork the documentation to your own namespace so that you can make a merge request with your documentation suggestion.

 We like [Gitlab's approach](https://about.gitlab.com/handbook/git-page-update/#where-should-content-go): If you're not sure where to put something in documentation, or if it even is documentation, [write a blog post](https://agaric.com/node/add/blog).  Or even, in the Agaric context, just throw it in a [raw note](https://gitlab.com/agaric/resources/raw-notes) (this private repository automatically publishes non-draft notes publicly to [agaric.gitlab.io/raw-notes](https://agaric.gitlab.io/raw-notes/)).
