My suggestions: First, a breakdown of the Government offices and their powers. Next an explanation of the election process, term length, eligibility to run and vote, etc. Also a list of protected rights, such as for a citizen to speak without government censure as long as they don't call for violence/ harrass people (that's one I'm really opinionated about) and more. Finally, an article with an established method to amend the constitution, since we will probably not cover everything.
