Documentation
=============

Documentations are written under the ``docs/`` directory as ReStructuredText (``.rst``) files. ``index.rst`` is the main page. A Tutorial on ReStructuredText can be found `here <https://pythonhosted.org/an_example_pypi_project/sphinx.html>`_.

API References are automatically generated by `Sphinx <http://www.sphinx-doc.org/en/stable/>`_ according to the outlines under ``docs/api/`` and should be modified when any code changes.

To compile documentation into webpages, run

.. code-block:: bash

    make html

under the ``docs/`` directory. The generated webpages are in ``docs/_build`` and can be viewed with browsers.
