Looking for wiki/documentation site designs

I’m looking for designs fitting a documentation-alike website where there is a lot of long article pages, detailed one page categories with one-line article lists (like some wikis) and low/none amount of pretty graphics as the layout parts.

Something with modern colors, good typography, and very good navigation / page structure for such site (and not a news site with a lot of aside elements, hunting for page views with excessive pagination and so on).
