3. How to configure it?
4. How to administrate it? 
4.1 Setup users

8.x what it is, how it works, how to use it etc.

11. Some input on CouchDB internals
12. Troubleshooting, common problems and their solutions
13. Some glossary of common terms to easily understand by new users
14. Release notes and changes history to track features.
and so on. For sure, some points need to be more detail like

As the inspiration source the PostgreSQL docs was used:
: I believe, that better to guide users to use Futon for the first steps instead of fighting with curl on CLI.
: Should docs promote tools like erica, kanso and other popular ones that are still been recommended on mailing lists/IRC? Question may also stands as "how much batteries to include?".
: GeoCouch, Lucene, OX_Auth, etc. and how to write your own. Same question about promotion of third party tools. On one hand they are third party, but on other they are not so much to stay aside and raising initial interest to them may provoke to create more of them.
