I have a quick question for you about numbered heads in documents.
In general, numbered section heads use the chapter number as the first digit – but that’s only if you have multiple chapters in a book (1.1, 2.1, 3.1â€¦).
What if you have only one chapter in a book? Do the sections become 1, 2, 3â€¦?
I havenâ€™t been able to find anything discussing this, so if you know of any reference material to back this up, Iâ€™d be much obliged!
