+//| :mod:`digitalio` --- Basic digital pin support
+//| =================================================
+//|
+//| .. module:: digitalio
+//|   :synopsis: Basic digital pin support
+//|   :platform: SAMD21, ESP8266
+//|
+//| The `digitalio` module contains classes to provide access to basic digital IO.
+//|
+//| Libraries
+//|
+//| .. toctree::
+//|     :maxdepth: 3
+//|
+//|     DigitalInOut
+//|
+//| All classes change hardware state and should be deinitialized when they
+//| are no longer needed. To do so, either call :py:meth:`!deinit` or use a
+//| context manager.
+//|
+//| For example::
+//|
+//|   import digitalio
+//|   from board import *
+//|
+//|   with digitalio.DigitalInOut(D13) as pin:
+//|     print(pin.value)
+//|
+//| This example will initialize the the device, read
+//| :py:data:`~digitalio.DigitalInOut.value` and then
+//| :py:meth:`~digitalio.DigitalInOut.deinit` the hardware.
+//|
+//| Here is blinky::
+//|
+//|   import digitalio
+//|   from board import *
+//|   import time
+//|
+//|   with digitalio.DigitalInOut(D13) as led:
+//|     led.switch_to_output()
+//|     while True:
+//|       led.value = True
+//|       time.sleep(0.1)
+//|       led.value = False
+//|       time.sleep(0.1)
