gambrel roof for 20x20 shed

We are building a shed that is 20x20. We want to put a gambrel roof on it but do not know where to begin to determine the pitch, angles, and length of rafters. Can someone explain to us how to determine these things? The walls of the shed are 8' tall. We really do not care how tall the shed is as long as it is not taller than our house (probably 15'). We are going to install flooring for an upper level for storage.

Truss Design

The article near the bottom of this page describes a good approach to your truss design:

The Super-simple Gambrel Roof

Once you get the first set of 2x's cut for the first truss, use them as patterns for the remaining cuts.
