+Guidelines for Contributing
+===========================
+
+PyPika welcomes contributions in all forms. These may be bugs, feature requests, documentation, or examples. Please feel free to:
+
+#. Submitting an issue
+#. Opening a pull request
+#. Helping with outstanding issues and pull requests 
+
+Open an issue
+-------------
+
+If you find a bug or have a feature request, please `open an issue <https://github.com/kayak/pypika/issues>`_ on GitHub. Please just check that the issue doesn't already exist before opening a new one.
+
+Local development steps
+-----------------------
+
+Create a forked branch of the repo
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Do this once but keep it up to date
+
+#. `Fork the kayak/PyPika repo GitHub <https://github.com/kayak/pypika/fork>`_
+#. Clone forked repo and set upstream
+
+    .. code-block:: bash
+
+        git clone [email protected]:<your-username>/pypika.git
+        cd pypika
+        git remote add upstream [email protected]:kayak/pypika.git
+
+Setup local development environment
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+#. Setup up python virtual environment
+
+    Create and activate the environment. Here is an example using ``venv`` from the standard library:
+
+    .. code-block:: bash
+
+        python -m venv .venv
+        source .venv/bin/activate
+
+#. Install python dependencies for development
+
+    With the virtual environment activated, install the development requirements, pre-commit, and the package itself:
+
+    .. code-block:: bash
+
+        make install
+
+#. Run the tests
+
+    The unit tests are run with ``unittest`` via ``tox``. To run the tests locally:
+
+    .. code-block:: bash 
+
+        make test
+
+    These tests will also run on GitHub Actions when you open a pull request.
+
+#. Build the docs locally
+
+    Our docs are built with Sphinx. To build the docs locally:
+
+    .. code-block:: bash 
+
+        make docs.build
+
+    Open the docs in your browser. For instance, on macOS:
+
+    .. code-block:: bash
+
+        open docs/_build/index.html
+
+Pull Request checklist
+----------------------
+
+Please check that your pull request meets the following criteria:
+
+- Unit tests pass
+- pre-commit hooks pass
+- Docstring and examples and checking for correct render in the docs
+
+Documentation
+-------------
+
+Documentation is built with Sphinx and hosted on `Read the Docs <https://pypika.readthedocs.io/en/latest/>`_. The latest builds are displayed on their site `here <https://readthedocs.org/projects/pypika/builds/>`_.
+
+The code documentation is to be written in the docstrings of the code itself or in the various ``.rst`` files in project root or the ``docs/`` directory.
+
+The docstrings can be in either `Numpy <https://numpydoc.readthedocs.io/en/latest/format.html>`_ or `Sphinx <https://sphinx-rtd-tutorial.readthedocs.io/en/latest/docstrings.html>`_ format.
+
+Automations
+-----------
+
+We use `pre-commit <https://pre-commit.com/>`_ to automate format checks. Install the pre-commit hooks with the ``make install`` command described above.
+
+GitHub Actions runs both format checks and unit tests on every pull request.
+
+**NOTE:** The hosted documentation is built separately from the GitHub Actions workflow. To build the docs locally, use the ``make docs.build`` command described above.

 PyPika is divided into a couple of modules, primarily the ``queries`` and ``terms`` modules.

+---------------

+This contains all of the dialect specific implementations of the ``Query`` class.

-This module contains the classes which represent individual parts of queries that extend the ``Term`` base class.
+Enumerated values are kept in this package which are used as options for Queries and Terms.
