That's the correct file. Around line 216, it says:

* For inserting fixed width text blocks (for code examples, use case
  examples, etc.), use ``::`` for anything that doesn't really benefit
  from syntax highlighting, especially short snippets. Use
  ``.. code-block:: <language>`` for longer code blocks that benefit
  from highlighting. For a short snippet of code embedded in the text, use \`\`.


so it's just for a (short) code example block, fixed font...
