How to create Drum tracks?

I’m new to using cubase and very confused. How do you go about creating drum tracks with your OWN drum samples you download online? I downloaded some drum samples but have no idea how to use them to create drum tracks. Nor do I actually know how to create any kind of drum track in cubase at all. Anyone help me? I’m using Cubase 5 btw.

Drag the each sample on a pad in Groove Agent One and start. Goto Youtube, it’s plenty of videos to show you how.
