\end{document}
in which,before the end of document I've included \bibliographystyle and /bibliography as suggested from various guides. Created bib file named as bibliografia
@misc{
pippo,
title={site1},
note={note1}
}
and then i try in any latex page to use the command \cite{pippo} (keyword). Over leaf gives me a warning
LaTeX Warning: Citation `pippo' on page 1 undefined on input line 8
where page 1 input line 8 is where I use the command \cite. How can I make it work ? I just need a bibliography but for websites.
