The section titles are unreadable/not-prominent here: http://docs.mongodb.org/master/reference/configuration-options/#httpinterface (see nojournal for example)

This makes it very hard to pick-out the important sections and options.

I would suggest making the size larger than the body and bolding the text. It might even make sense to make each into a delineated section by underling the title, or changing the background color of the content.

Maybe like one of these:

• http://nagios.sourceforge.net/docs/3_0/configmain.html
• http://supervisord.org/configuration.html
• http://jekyllrb.com/docs/configuration/
