It finds World of Warcraft on your computer, adds the Homerealm add-on to the game and starts the Homerealm app, which sends your journey to your account and keeps the add-on up to date by itself. It never asks for a password or for an administrator, and it shows each step as it goes. Then start the game, or type /reload if it is already open.
