\section{Introduction}
Present as you wish, for instance: this paper is about \cite{berge:60}, and goes way beyond.
\begin{lemma}\label{lem:main-lemma}
The Petersen graph has 10 vertices.
\end{lemma}
\begin{theorem}
The graph obtained by the disjoint union of two Petersen graphs has 20 vertices.
\end{theorem}
\begin{proof} If suffices to observe that the order of a graph is additive with respect to its connected components, apply Lemma~\ref{lem:main-lemma} twice, and make the corresponding calculation correctly.
\end{proof}
\section{Concluding remarks}
We think that this was an amazing paper.
