Properly show title and author in latex generated from markdown using pandoc

template.tex:

\begin{document}

\section{$title$}

\begin{center}
$author$
\end{center}


$body$

\end{document}

(I use \section{} for title because it corresponds to # in markdown.)

Markdown metadata:

---
title: 'The Title'
author:
  - 'Author 1'
---
