+## The Musical Walking Stick tutorial on the Adafruit Learning System
+
+The code in this repo accompanies the Adafruit tutorial
+Musical Walking Stick
+https://learn.adafruit.com/musical-cane/
+
+The *appropriate code file file should be copied onto the **CIRCUITPY** flash drive as **code.py** that appears 
+when you plug the CircuitPlayground Express into your computer via a known good USB cable. 
+
+If the only drive name you get is named **CPLAYBOOT**, CircuitPython may not be loaded 
+on the board. You can load CircuitPython [per this guide](https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-quickstart). Then you should be able to see the **CIRCUITPY** drive when connected via USB.

+CircuitPython resources may be found at https://CircuitPython.Org/
