The next/remarks.example.md filename is kind of a misnomer but it was
named this way to match Makefile.example. It has brief instructions
along with a link to the FAQ about what one should put in their
remarks.md file (and the FAQ links to the new file as a starting point
as it has instructions).
The markdown guidelines were updated to note that if one does use
sections in remarks.md file they should start out at heading level 3
(###) and for each subsection increment it by one (up to level 6).
