+The files are located in PiFinders GitHub repository under ``docs/source`` and have 
+the ending ``.rst``. We publish the documentation to `redthedocs.io <eadthedocs.io>`_ manually. 
 
+For reviewing your changes to the docs locally, install sphinx into your development environment using pip:
+
+.. code-block::
+
+    pip install sphinx sphinx_rtd_theme 
+
+and then use the supplied Makefile using ``make html``. 
+The docs are then stored in ``build/html``. To serve it locally run ``python -m http.server`` in the html directory.
