-That's an absolutely new OpenFreebuds implementation, rewritten
-from scratch to asyncio & Qt6. Currently it's still in progress
-and a lot of features are missing, and only supported device
-is FreeBuds 5i. Stay turned, in some day this version will 
-become main.
-
-If you want to test, do this at your own risk:
-
-```shell
-poetry install
-poetry run pyuic6 openfreebuds_qt/designer
-poetry run python -m openfreebuds_qt -v
-```
-
-Don't send bugreports, I know that it's absolutely broken.
-But, at least, it should show a tray icon and main window
-in Win10-11 or KDE.
