Footnotes are less commonly used in technical documentation on the web compared to traditional printed documents, or at least this is my own personal experience on the matter. This is because footnotes are typically designed to provide additional explanatory or contextual information on the same page, and the structure of web pages and the nature of online content consumption often prioritize a more scannable and hyperlinked format.
My question is whether you should clarify if by "hooks" you mean React hooks or Wordpress hooks and use a footnote to clarify this fact inside your technical documentation.
In the document, it is obvious I am talking about Wordpress hooks, but the example is found 2 paragraphs later and the example is not easy to read, but I can't change the example, because it's a particular bit of code in our React, Wordpress solution. Should you still include the footnote even if not necessary. What are some guidelines for this if there's any?
