Creating a model image

I have yet to find a single, comprehensive, step-by-step list, so I'm asking if there is one. Here's my situation:

- I'd like one model image I can deploy to multiple models of PC with the drivers in a sysprep answer file.

- The computers will all be on a domain.

- The model image is Windows 7 64-bit.

I'm looking for the exact steps in the GSS console I should take to create this image.

Thanks!
