Hacking What happens if I click "install game" icon on Wiiflow

I don't remember well if it's "install game" exactly or not cause I'm not at home right now but the meaning is almost same.
You could see the icon "install game" when you click the settings after chosing the games. I didn't click so far but now I wonder what does this button do? Does anyone know this button's function?

if you have a Wii game disc in your Wii, it will install the game to your hard drive without the need to use your computer.
