+==========================
+About Python Documentation
+==========================
+
+This directory, ``py/docs``, is the source for the API Reference Documentation
+and basic Python documentation as well as the main README for the GitHub and
+PyPI package.
+
+
+How to build docs
+=================
+
+One can build the Python documentation without doing a full bazel build. The
+following instructions will build the setup a virtual environment and installs tox, clones the
+selenium repo and then runs ``tox -c py/tox.ini`` building the Python documentation.
+
+.. code-block:: console
+
+    virtualenv test-py38-env
+    source test-py38-env/bin/activate
+    pip install tox
+    git clone [email protected]:SeleniumHQ/selenium.git
+    cd selenium/
+    # uncomment and switch to your development branch if needed 
+    #git switch -c feature-branch origin/feature-branch
+    tox -c py/tox.ini
+
+Works in similar manner as the larger selenium bazel doing just the python documentation portion.
+
+What is happening under the covers of tox, sphinx
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+tox is essentially a build tool for Python. Here it setups its own virtualenv and installs the
+documentation packages (sphinx and jinja2) as well as the required selenium python
+dependencies. Then tox runs the sphinx generate autodoc stub files and then builds the docs.
+
+Sphinx is .. well a much larger topic then what we could cover here. Most important to say
+here is that the docs are using the "classic" theme and than the majority of the api documentation
+is autogenerated. There is plenty of information available and currently the documentation is
+fairly small and not complex. So some basic understanding of restructed text and the Sphinx tool chain
+should be sufficient to contribute and develop the Python docs.
+
+To clean up the build / tox cache
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Although there is a Sphinx Makefile option to clean up using the tox environment above one can
+manually clean the build by deleting the build directory on the root (selenium/build using the
+default directory on git clone). Noting that both Sphinx and tox cache parts of their build and
+recognize changes to speed up their respective builds. But at times one wants to start fresh
+deleting the aformentioned directory will clean the Sphinx cache or removing selenium/py/.tox 
+directory for cleaning the tox environment.
+
+
+Known documentation issues
+==========================
+The API Reference primarily builds from the source code. But currently the initial template stating
+which modules to document is hard coded within py/docs/source/api.rst. So if modules are added or
+removed then the generated docs will be inaccurate. It would be preferred that the API docs generate
+soley from the code if possible. This is being tracked in `#14178 <https://github.com/SeleniumHQ/selenium/issues/14178>`_
+
+We are working through the Sphinx build Warnings and Errors trying to clean up botht the syntax and
+the build.
+
+Contributing to Python docs
+===========================
+First it is recommended that you read the main `CONTRIBUTING.md <https://github.com/SeleniumHQ/selenium/blob/trunk/CONTRIBUTING.md>`_.
+
+Some steps for contibuting to the Python documentation ..

+- Check out changes locally using instruction above.
+- Try to resolve any warnings/issues.
+  - If too arduous either ask for help or add to list of known issue.
+- If this process is updated please update this doc as well to help the next person.
