I have a query, I would like to combine a blog into a static XHTML/CSS site. I can see that there are many sites on ThemeForest that are coded in XHTML/CSS that contain a 1 page blog in their sites apart from their Home, Services, Portfolio, Contact, etc pages.

Can someone please recommend if I have a coded brochure site in XHTML and I want to add a 1 Page Blog to the site - how would I go about doing that?

Would I need to slice the PSD of the layout and have it coded in Wordpress and then install Wordpress onto the server and combine it with the site?

I am after the actual process of how I would go about it as this has been haunting me for months and I am eager to add this feature to sites.

I look forward to any suggestions or help please.
