doc: Clarify that adding docs follows dev process and add into howtos

Also add link to "How to add new doc" into a collection of
Contributors howtos.

The doc stays in root of docs, and also in the main left-side
menu on the website, so that it is very easy to discover. Everyone
who has even the slightest motivation to update the docs, should
be able to find instructions easily.

 How to add or update docs
 =========================

+Documentation files live in ``/doc`` directory in the source tree, so
+adding or updating documentation follows the same process as changing
+the code. If you've never done it before, start by carefully
+reading the :doc:`/dev_guide/development_guide`.
+
 To add or update a documentation page, you need to create or modify
 an ``.rst`` file in the ``/doc`` directory and send a patch for
 review.
