Footnotes
Highlight: Avoid writing footnotes in documentation.
A footnote is an annotation provided at the end of a paragraph, chapter, or a page with additional information related to the content.
Rather than using a footnote, you can use a note, a link, use parentheses, or dashes.
If there is no alternative than using a footnote, then use a symbol instead of a number. Use the symbols: *, †, ‡, §, ‖, ¶ – preferably in that order.
