css js reserved custom fields not in instructions

While working on another theme, I encountered a question about the js reserved custom field.

“I don’t understand where have I to include the javascript:”

So I went to the instructions and could not find them there.

Maybe you can include instructions for css and js reserved custom fields with the next update. ??
