Generally, all you have to do is drill a hole in the right place and screw in the knob - screw on the inside, cabinet knob on the outside. The tip of the screw goes through the cabinet door or drawer and into the hole at the base of the knob. The tricky part is usually finding the right place on the cabinet door or drawer. For that, take some measurements - preferably several times, since messing this up will give you a rather ugly hole in the wrong place of the cabinet. Mark the spot with a pen or pencil and drill that hole, which should be narrower than the screw is thick.
