wants to write new documentation, but isn't familiar with Sphinx.

+==========================
+Sphinx Quickstart Template
+==========================
+
+.. sectionauthor:: Sean Silva <silvas@purdue.edu>
+
+Introduction and Quickstart
+===========================
+
+This document is meant to get you writing documentation as fast as possible
+even if you have no previous experience with Sphinx. The goal is to take
+someone in the state of "I want to write documentation and get it added to
+LLVM's docs" and turn that into useful documentation mailed to llvm-commits
+with as little nonsense as possible.
+
+You can find this document in ``docs/SphinxQuickstartTemplate.rst``. You
+should copy it, open the new file in your text editor, write your docs, and
+then send the new document to llvm-commits for review.
+
+Focus on *content*. It is easy to fix the Sphinx (reStructuredText) syntax
+later if necessary, although reStructuredText tries to imitate common
+plain-text conventions so it should be quite natural. A basic knowledge of
+reStructuredText syntax is useful when writing the document, so the last
+~half of this document (starting with `Example Section`_) gives examples
+which should cover 99% of use cases.
+
+Let me say that again: focus on *content*.
+
+Once you have finished with the content, please send the ``.rst`` file to
+llvm-commits for review.
+
+Guidelines
+==========
+
+Try to answer the following questions in your first section:
+
+#. Why would I want to read this document?
+
+#. What should I know to be able to follow along with this document?
+
+#. What will I have learned by the end of this document?
+
+Common names for the first section are ``Introduction``, ``Overview``, or
+``Background``.
+
+If possible, make your document a "how to". Give it a name ``HowTo*.rst``
+like the other "how to" documents. This format is usually the easiest
+for another person to understand and also the most useful.
+
+You generally should not be writing documentation other than a "how to"
+unless there is already a "how to" about your topic. The reason for this
+is that without a "how to" document to read first, it is difficult for a
+person to understand a more advanced document.
+
+Focus on content (yes, I had to say it again).
+
+The rest of this document shows example reStructuredText markup constructs
+that are meant to be read by you in your text editor after you have copied
+this file into a new file for the documentation you are about to write.
+
+Example Section
+===============
+
+Your text can be *emphasized*, **bold**, or ``monospace``.
+
+Use blank lines to separate paragraphs.
+
+Headings (like ``Example Section`` just above) give your document
+structure. Use the same kind of adornments (e.g. ``======`` vs. ``------``)
+as are used in this document. The adornment must be the same length as the
+text above it. For Vim users, variations of ``yypVr=`` might be handy.
+
+Example Subsection
+------------------
+
+Make a link `like this <http://llvm.org/>`_. There is also a more
+sophisticated syntax which `can be more readable`_ for longer links since
+it disrupts the flow less. You can put the ``.. _`link text`: <URL>`` block
+pretty much anywhere later in the document.
+
+.. _`can be more readable`: http://en.wikipedia.org/wiki/LLVM
+
+Lists can be made like this:
+
+#. A list starting with ``#.`` will be automatically numbered.
+
+#. This is a second list element.
+
+   #. They nest too.
+
+You can also use unordered lists.
+
+* Stuff.
+
+  + Deeper stuff.
+
+* More stuff.
+
+Example Subsubsection
+^^^^^^^^^^^^^^^^^^^^^
+
+You can make blocks of code like this:
+
+.. code-block:: c++
+
+   int main() {
+     return 0
+   }
+
+For a shell session, use a ``bash`` code block:
+
+.. code-block:: bash
+
+   $ echo "Goodbye cruel world!"
+   $ rm -rf /
+
+If you need to show LLVM IR use the ``llvm`` code block.
+
+Hopefully you won't need to be this deep
+""""""""""""""""""""""""""""""""""""""""
+
+If you need to do fancier things than what has been shown in this document,
+you can mail the list or check Sphinx's `reStructuredText Primer`_.
