Where do I put the navigation?

I have a template that I use for all my repository pages (as you can see, I’m a big fan of minimalist designs):

Most of the pages are 1 page long, so a navigation or menu bar aren’t necessary. However, one of my recent projects has several help pages, which include a small handful of pages like “Usage”, “Installation”, “Advanced config options”, “Generate API Key”.

The problem is, I’m not sure how to fit any sort of navigation in without breaking the page design. Does anyone have any ideas?

Do I just put a list of links at the beginning or end of each page, or is there a nicer way to fit a menu or set of links in?
