\section{Conclusions}\label{section:conc} 

First summarize the paper.  Include a paragraph on lessons learned.
You can include future work as a paragraph in the conclusion section
or use a separate section. Include any other concluding thoughts. For example, 
with respect to writing documents, I want to add the following:
\begin{itemize}
\item Spell check your document.
\item Print your document, read it at least once, mark corrections using pen or pencil, and make the changes.
\item I recommend reading the entire document at least two times.
\item Avoid footnotes.
\item Avoid parenthetical remarks.
\end{itemize}

End with a paragraph or a few sentences on the broad impact of the
work.
