How do I install a one knob delta shower faucet

Well, that depends...

Exactly what are you doing? Are you replacing an old valve...if so, is it a one, two or three handle valve in place now? If you are removing an old valve, you remove it and then install the new valve...not much else I can tell you here.

Are you installing a new valve? If so, you need a hot water pipe and a cold water pipe and then you hook the valve up as per instructions that are with the valve.

Good luck!
