 //| """Hardware accelerated external bus access
 //|
-//| The `busio` module contains classes to support a variety of serial
-//| protocols.
-//|
-//| When the microcontroller does not support the behavior in a hardware
-//| accelerated fashion it may internally use a bitbang routine. However, if
-//| hardware support is available on a subset of pins but not those provided,
-//| then a RuntimeError will be raised. Use the `bitbangio` module to explicitly
-//| bitbang a serial protocol on any general purpose pins.
-//|
-//| 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 busio
-//|   from board import *
-//|
-//|   i2c = busio.I2C(SCL, SDA)
-//|   print(i2c.scan())
-//|   i2c.deinit()
-//|
-//| This example will initialize the the device, run
-//| :py:meth:`~busio.I2C.scan` and then :py:meth:`~busio.I2C.deinit` the
-//| hardware. The last step is optional because CircuitPython automatically
-//| resets hardware after a program finishes."""
+//| The I2CDevice and SPIDevice helper classes make managing transaction state on a bus easy. 
+//| For example, they manage locking the bus to prevent other concurrent access. For SPI
+//| devices, it manages the chip select and protocol changes such as mode. For I2C, it
+//| manages the device address.
