Design Extender Getting Started Guide

Dear Jason, I'm using the getting started guide to familiarise myself with Design Extender. I'm following the steps - (1) create a CSS based layout vis CSS Sculptor, (2) I've added horizontal menus to this via CSS Menu writer and I've saved it as a html file. I have save this as a template. But it's at the next step I become a cropper - building the site with Site Sculptor. My question is how do I select this design I've just created to be the basis/foundation of the site I wish to make. In the 'Site Sculptor Getting Started Guide' under the heading 'Using your own template - point number 1 says - 'use the Add Layout wizard prior...' - where is this Add Layout wizard located. In site sculptor I am presented with the Site Sculptor screen, but how do I select my file or design I've just created with the previous two extensions and built the site using my recently created html file/doc? Where do I find the presets that I saved in the previous two extensions to include in Site Sculptor. Note: I used 'Administration: All' template to build the menu.
