footnotes

Footnote labels are established with references enclosed in square brackets and trailing underscore::

place a footnote here [1]_ please.

The footnote label is either a number or a # (hash). Occurrences in the text of [#]_ or [3]_ link to the set of footnotes found in following incantation of

.. rubric:: Footnotes
.. [#] first footnote here
.. [3] third footnote

Footnotes

[1]	first anonymous footnote

[3]	third footnote

citations

These are of the same form as footnotes, but are any text except hashes and numbers. They can be referenced from any file in the document tree. See the sphinx documentation for more details (or the source of this page)[Ref]_
