Does it work correctly on Switch 2?

That would be good to add to the readme, but if yes this line should be genericized to cover Switch 2 microSD Express cards as well.

Switch: Download the .nro file and copy it into the switch/ directory on your SD card.
Switch: Download the .nro file and copy it into the switch/ directory on your Switch memory card.

No, the switch 2 isn't modded therefor this can not work on there.
If there's a userland exploit within switch 1 backwards compatibility it might work, but currently there is no way to run nro homebrew
