Problem already solved, I didn't upload my .bib file.

I used
```
\bibliographystyle{unsrt}
\bibliography{references}
```
in TexWorks and it works perfectly, but I recently started using Overleaf. I find it is not convenient if I type the details of every reference, something like:

\begin{thebibliography}{}
\bibitem[details of the reference
\end ...
