Parts of the text in reST source can be “commented out”:
Any text which begins with an explicit markup start but doesn’t
use the syntax of any of the constructs above, is a comment.

, that is dot-dot-blank at the beginning of the
line, taking the indentation level into account.

It can spread over lines as

.. This text will not be shown,
but, for instance, in HTML might be
rendered as an HTML comment, if the html writer is set up for that.
.. here we start an unordered list:
.. this is another comment. Since it's within the list it is aligned
with 'two', which is the contents of the second list item
