\footnotetext ¶Synopsis, one of:
\footnotetext{text}
\footnotetext[number]{text}
Place text at the bottom of the page as a footnote. It pairs with
\footnotemark (see \footnotemark) and can come anywhere after
that command, but must appear in outer paragraph mode (see Modes).
The optional argument number changes the number of the footnote
mark.
See \footnotemark and Footnotes in a table, for usage
examples.
