Integrate wordpress into zencart store

I need to integrate my existing wordpress blog into my zencart 1.5 store. A recommended solution can be found on the numinix blog (google numinix zencart wordpress integration). Afer the integration is complete my developer will need clear instructions for how to do this (he did not find the instructions on the numinix blog sufficient) for our other zencart store domains. The idea is that the blog which is now located at [login to view URL] will be visible as a page in the zencart store, such that the zencart sidebars that display product and information links are visible and the headers and footers remain as the zencart store. A more detailed explanation with instructions is available on the numinix site.
