+Environment Variables
+=====================
+
+CircuitPython 8.0.0 introduces support for environment variables. Environment
+variables are commonly used to store "secrets" such as Wi-Fi passwords and API
+keys. This method *does not* make them secure. It only separates them from the
+code.
+
+CircuitPython supports these by mimicking the `dotenv <https://github.com/theskumar/python-dotenv>`_
+CPython library. Other languages such as Javascript, PHP and Ruby also have
+dotenv libraries.
+
+These libraries store environment variables in a ``.env`` file. Here is a simple
+example:
+
+.. code-block:: bash
+
+  KEY1='value1'
+  # Comment
+  KEY2='value2
+  is multiple lines'
+
+CircuitPython uses the ``.env`` at the drive root (no folder) as the environment.
+User code can access the values from the file using `os.getenv()`. It is
+recommended to save any values used repeatedly in a variable because `os.getenv()`
+will parse the ``/.env`` on every access.
+
+CircuitPython behavior
+----------------------
+
+CircuitPython will also read the environment to configure its behavior. Other
+keys are ignored by CircuitPython. Here are the keys it uses:
+
+CIRCUITPY_WIFI_PASSWORD
+~~~~~~~~~~~~~~~~~~~~~~~
+Wi-Fi password used to auto connect to CIRCUITPY_WIFI_SSID
+
+CIRCUITPY_WIFI_SSID
+~~~~~~~~~~~~~~~~~~~
+Wi-Fi SSID to auto-connect to even if user code is not running.
