Replacing old switch with dimmer

Ok so this would seem pretty basic but I am looking to replace a light switch with a dimmer switch.

Problem I have is that the dimmer switch has 2 black wires and a green wire coming out of it and the old switch has 3 black wires attached to it.

I am guessing the power is coming to the switch and then going to the light and going to another location as well.

How do I go about wiring this ?

Do I just have to connect 2 of the black wires to one of the wires from the switch ? And if so then how do I know which 2 ?

TIA

The two connected to the same terminal of the switch. That is the screw and the quick connect at that screw.

You will be combining the two circled black wires.
