Item description:

This Homebrew dumps all the tickets and keys of your installed Wii-U games. If you press "A" or "B", the ticket and the key from the currently inserted game will be dumped. Everything ends up in the folder SD: // tik2sd, disc tickets end up in an "odd" folder. The whole thing takes only a few seconds.

If you have dumped a disc ticket, you can do this for example. With uTikDownloadHelper and download your game legally from the NUS. You will then get a folder, the contents of which you can install with the WUP installer. Voilá: You have already installed a disc game in the Wii-U-Menu!
