Having Trouble With Getting Game Booster To Add League Of Legends

[LEFT]I had trouble from the start when Game Booster didn't manage to find LoL. when I tried to add it I didn't really know what to do so I tried to find the place of the League of Legends.exe file ,which was moved to the Game folder (at least I think this is the right one) in the Riot Games folder. But with that I am not sure what to do. If anyone can please explain to me how to connect LoL to the Game Booster. P.S because League of Legends.exe only starts to work when a game is starting do you need to start the Game Booster when the game starts or does it have a different time to turn on? [/LEFT]
