-Building locally
-================
-
-Zip release files
------------------
-
-To build this library locally you'll need to install the
-`circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>`_ package.
-
-.. code-block:: shell
-
-    python3 -m venv .env
-    source .env/bin/activate
-    pip install circuitpython-build-tools
-
-Once installed, make sure you are in the virtual environment:
-
-.. code-block:: shell
-
-    source .env/bin/activate
-
-Then run the build:
-
-.. code-block:: shell
-
-    circuitpython-build-bundles --filename_prefix adafruit-circuitpython-veml6075 --library_location .
-
-Sphinx documentation
------------------------
-
-Sphinx is used to build the documentation based on rST files and comments in the code. First,
-install dependencies (feel free to reuse the virtual environment from above):
-
-.. code-block:: shell
-
-    python3 -m venv .env
-    source .env/bin/activate
-    pip install Sphinx sphinx-rtd-theme
-
-Now, once you have the virtual environment activated:
-
-.. code-block:: shell
-
-    cd docs
-    sphinx-build -E -W -b html . _build/html
+Documentation
+=============
 
-This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to
-view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
-locally verify it will pass.
