As mentioned in se-edu/learningresources#62 (comment):
Also feels kind of obtuse to be adding head: head.md to every document as in se-edu/learningresources@90f6492 , can it be set in the site.json?
Reconsider the design for head: head.md to be more simple for the user to use. Perhaps some additional configuration settings in site.json?
Currently, footer and site-nav has the same design issue.
