+//| """Basic digital pin support
+//|
+//| The `digitalio` module contains classes to provide access to basic digital IO.
+//|
+//| All classes change hardware state and should be deinitialized when they
+//| are no longer needed if the program continues after use. To do so, either
+//| call :py:meth:`!deinit` or use a context manager. See
+//| :ref:`lifetime-and-contextmanagers` for more info.
+//|
+//| For example::
+//|
+//|   import digitalio
+//|   import board
+//|
+//|   pin = digitalio.DigitalInOut(board.LED)
+//|   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 time
+//|   import digitalio
+//|   import board
+//|
+//|   led = digitalio.DigitalInOut(board.LED)
+//|   led.direction = digitalio.Direction.OUTPUT
+//|   while True:
+//|       led.value = True
+//|       time.sleep(0.1)
+//|       led.value = False
+//|       time.sleep(0.1)
+//|

+//| Learn guide <https://learn.adafruit.com/circuitpython-essentials/circuitpython-digital-in-out>`_
