The dimmer switch typically comes with several wires pre-attached. In a standard setup, the two 'hot' wires from the house's electrical system (often black or identified as line/load) will be connected to the two black wires coming from the dimmer switch. Twist the exposed ends of the corresponding wires together and secure them with a wire nut. The bare copper or green insulated wire from the house (ground wire) should be connected to the green ground wire on the dimmer switch, also secured with a wire nut. Any 'common' wires (typically white neutral wires, though sometimes they are bundled and not connected to the switch itself) should be connected together with their own wire nut if they were previously connected to each other.
