Tracks

I want to use a track system on my robot. I ordered two of the
Lynxmotion Track - 2" Wide x 21 Links ~23" TRK-01
and 4 pairs of the Lynxmotion Track Sprocket - 6 Tooth.
What else would I need to complete the system?
Does anyone have a diagram of how it should look?
please advise. Thank You

Can you provide a drawing or sketch of how you want to have one side of the tracks set up? This will help us help you determine what else is needed.
