Once you've finished setting up your Feather M4 Express with CircuitPython, you can add these libraries to the lib folder:
- adafruit_bitmap_font
- adafruit_bus_device
- adafruit_display_shapes
- adafruit_display_text
- adafruit_imageload
Then, you can click on the Download: Project Zip link below at the top of the code to download the code, bitmap, font and .mp3 files.

Your Feather M4 Express CIRCUITPY drive should look like this after you load the libraries, bitmap, font, .mp3 and code.py files:
