+--------
+
+Submitting a pull request is more than just code!
+To achieve a quality product, the *tests* and *documentation* need to be updated as well.
+An excellent pull request will include these in the changes, wherever relevant.

 Commit message formatting

 Use ``BREAKING CHANGE`` to trigger a ``major`` version change
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
 Adding ``BREAKING CHANGE`` to the footer of the extended description of the commit message will **always** trigger a ``major`` version change, no matter which type has been used.
 This will be appended to the changelog and release notes as well.
 To preserve good formatting of these notes, the following format is prescribed:

+Documentation
+-------------
+
+Toolchain
+^^^^^^^^^
+
+The documentation for this formula is written in
+`reStructuredText <https://en.wikipedia.org/wiki/ReStructuredText>`_
+(also known as RST, ReST, or reST).
+It is built by
+`Sphinx <https://en.wikipedia.org/wiki/Sphinx_(documentation_generator)>`_
+and hosted on
+`Read the Docs <https://en.wikipedia.org/wiki/Read_the_Docs>`_.
+
+Adding a new page
+^^^^^^^^^^^^^^^^^
+
+Adding a new page involves two steps:
+
+#. Use the
+   :ref:`saltstack_formulas_rst_page_template <provided page template>`
+   to create a new page.
+#. Add the page name under the ``toctree`` list in ``index.rst``.
+
+   #. Do not just append it to the list.
+   #. Select the best place where it fits within the overall documentation.
+
+SaltStack-Formulas' RST page template
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. _saltstack_formulas_rst_page_template
+
+Use the following template when creating a new page.
+This ensures consistency across the documentation for this formula.
+The heading symbols have been selected in accordance to the output rendered by the
+`Markdown to reStructuredText converter <https://github.com/miyakogi/m2r#restrictions>`_
+we are using for some of the pages of this documentation.

+#. The first line is an anchor that can be used to link back to (the top of)
+   this file.
+
+   #. Change this to be the lowercase version of the file name.
+   #. Do not include the ``.rst`` file extension.
+   #. Use hyphens (``-``) instead of spaces or non-letter characters.
+
+#. Change the ``[Page title]`` accordingly, matching the same number of ``=``
+   underneath.
+#. Change the ``[Introductory paragraph(s)]`` to be a short summary of the page
+   content.
+   Use no more than three paragraphs for this.
+#. Leave the ``..contents:: **Table of Contents**`` line as it is.
+#. Use the remaining headings as required to break up the page content.
+
+   #. You will rarely need to use beyond ``[Heading 4]``.
+   #. Again, no single heading should have more than about three paragraphs of
+   #. content before the next heading or sub-heading is used.
+
+Obviously, it is not necessary to follow the steps in the order above.
+For example, it is usually easier to write the ``[Introductory paragraph(s)]``
+at the end.

 All that follows is a proposal based on my experience with `SaltStack <http://www.saltstack.com/>`_. The good thing of a piece of software like this is that you can "bend it" to suit your needs in many possible ways, and this is one of them. All the recommendations and thoughts are given "as it is" with no warranty of any type.
