Review of technical docs following phpList (less) technical manual

Continuing the discussion from Is there a guide on how to setup a phpList development environment on my computer?:

Hi, we will soon be publishing the new phpList manual, and so we will need need to review the docs in the wiki and remove anything from the wiki that is duplicated in the manual. Thiis won’t be much from the technical docs I suppose, however, however, it’s a good time to start afresh and improve those docs. The API is coming soon too, so we can write about that as well.

Please list any other things that could be improved here.
