This is a tool designed to assist in the installation of Luma3DS onto a 3DS system.
It comes with usage instructions built in.
It is designed for people who either are unsure of where to copy files on the SDCard, or people who just want to save time.
Really all it does is organize your Homebrew and games (CIA files) into a tidy list, allowing you to choose what items to install, and push one button to do so. I find it VERY handy, as I install a lot of CFW on friends consoles, and this makes the process MUCH faster and easier.
IT WILL REQUIRE AN NTRBOOT CAPABLE R4 CARD!
