TGB Platformer Kit

Alright, i'm working on the platformer kit tutorial and it doesn't say anywhere in it how to keep your character focused in the camera as you play. Am i just blind or if i'm not, why isn't it in the tutorial?

How do you go about doing it? If you ask me you should be able to just click and drag a "camera source" icon onto whatever object you want the camera to center to in the program. Would be soo much easier.
