Shortly after posting this project our friends at Adafruit found it and got in touch with me. They asked if I'd write a guide that covers the usage of this application for publishing on learn.adafruit.com. I am happy to announce that the guide is now finished and live! You can find it here: https://learn.adafruit.com/using-the-android-circuitpython-editor and I've added it to the project links. Big thanks to Adafruit for the opportunity.
