Trouble adding material to imported obj file car

I’m trying to add a low poly car to a scene I made in Blender following The tutorial says to download a car from I did that and imported the car obj file on its own layer. How do I add the material (that it comes with as a separate jpg file) to it? It’s not explained in the tutorial nor on the turbosquid site. The tutorial is done in Cycles. I’m a beginner so hopefully there’s an easy explanation.

Never mind. I figured it out.
