-How To - Project Documentation
-======================================================================
-
-Get Started
-----------------------------------------------------------------------
-
-Documentation can be written as rst files in `lms/docs`.
-
-
-To build and serve docs, use the commands::
-
-    docker compose -f docker-compose.local.yml up docs
-
-
-
-Changes to files in `docs/_source` will be picked up and reloaded automatically.
-
-`Sphinx <https://www.sphinx-doc.org/>`_ is the tool used to build documentation.
-
-Docstrings to Documentation
-----------------------------------------------------------------------
-
-The sphinx extension `apidoc <https://www.sphinx-doc.org/en/master/man/sphinx-apidoc.html>`_ is used to automatically document code using signatures and docstrings.
-
-Numpy or Google style docstrings will be picked up from project files and available for documentation. See the `Napoleon <https://sphinxcontrib-napoleon.readthedocs.io/en/latest/>`_ extension for details.
-
-For an in-use example, see the `page source <_sources/users.rst.txt>`_ for :ref:`users`.
-
-To compile all docstrings automatically into documentation source files, use the command:
-    ::
-
-        make apidocs
-
-
-This can be done in the docker container:
-    ::
-
-        docker run --rm docs make apidocs
