 the documentation for Read the Docs is built using Sphinx and hosted on Read the Docs.
 The docs are kept in the ``docs/`` directory at the top of the source tree.
 
-.. TODO: expand this section explaining there the PR is automatically built and
-   the author can visualize changes without installing anything on their system.
-   However, if there is going to be periodic/bigger contributions, it may be a
-   good idea to install the Sphinx requirements to build our docs.

+Guidelines
+----------
 
 Please follow these guidelines when updating our docs.
 Let us know if you have any questions or something isn't clear.
 
 The brand
----------
+^^^^^^^^^
 
 We are called **Read the Docs**.
 The *the* is not capitalized.
 
 We do however use the acronym **RTD**.
 
 Titles
-------
+^^^^^^
 
 For page titles, or Heading1 as they are sometimes called, we use title-case.
 
 If the page includes multiple sub-headings (H2, H3),
 we usually use sentence-case unless the titles include terminology that is supposed to be capitalized.
 
 Content
--------
+^^^^^^^
 
 * Do not break the content across multiple lines at 80 characters,
   but rather break them on semantic meaning (e.g. periods or commas).
