The release thread has installation instructions.

Installation of the plugin.3gx, the backgrounds and the custom sounds:

• Download the .zip archive and extract it.
• Insert your SD card in your computer.
• Put the ".3gx" file, the both ".bmp" files and the "snd" folder in your SD card following one of these paths (depending on the MK7 region you have):

EUR - SD:/luma/plugins/0004000000030700
JPN - SD:/luma/plugins/0004000000030600
USA - SD:/luma/plugins/0004000000030800

Make sure you have plugins enabled under Rosalina, and press Select to open the menu while in game. Oh, and as a fair warning, don't use this on Pretendo unless you want to get banned. It's fine in single player, but you will get reported if using any of the cheats that give you an advantage in multiplayer.
