My guide for how to install on Mac Mini Late 2012 and other Catalina-capable devices, including WiFi: https://medium.com/@andv/how-to-install-big-sur-to-mac-mini-late-2012-9d674b563174
If your machine is not Catalina-capable, it may require additional steps, look in the "Common Issues" section.
Wifi will not work out of the box for most devices, but can be set up. Look up Common Issues -> Wifi Not Working.
If you have non-Metal GPU, graphics acceleration will not work for now.
This list is not complete, you can submit your successful attempt to the GitHub issues or add it yourself.
Tested on my own device, will require WIFI kext replacement.
Graphics acceleration will not work at the moment.

May require replacing GPU with Metal-capable.
