A comic strip of xkcd joking that the most unhelpful tool is one whose manual starts with "How to read this manual". — Image credit: “Manuals” from xkcd by Randall Munroe (https://xkcd.com/1343/)

Rather than begin with “How to read this manual” (hopefully, that task is sufficiently self-evident), this documentation ends with guidelines for writing future versions.
