 Usage Example
 =============
 
-At the time of writing (`git:7fc1f8ab <https://github.com/cefn/Adafruit_Micropython_Blinka/tree/7fc1f8ab477124628a5afebbf6826005955805f9>`_),
-the following sequence runs through some basic testing of the digitalio compatibility layer...
+The pin names may vary by board, so you may need to change the pin names in the code. This
+example runs on the Raspberry Pi boards to blink an LED connected to GPIO 18 (Pin 12):
