Notes on the OS images:

1. These images have a shrunken file system. On first boot they will expand the file system to occupy the whole of the SD card and then reboot. Please allow time for this process if trying to connect remotely.
2. Images are hosted on Google Drive.
3. Images use Wayland and are tested with TigerVNC for remote access.
4. Images are compressed with xz and can be wriiten to SD cards using the Raspberry Pi Imager.
5. Pi 4 images should also work on model Pi 3 model B+ (but we haven't tested them).
