\begin{document}
\section*{My first document}
This is a short example of a \LaTeX\ document I wrote on
\today. It shows a few simple features of automated
typesetting, including
\begin{itemize}
\item setting the default font size to 12pt;
\item specifying `article' type formatting;
\item using the Palatino typeface;
\item adding special formatting for URIs;
\item formatting a heading in `section' style;
\item using the \LaTeX\ logo;
\item generating today's date;
\item formatting a list of items;
\item centering and italicizing;
\item autonumbering the pages.
\end{itemize}
\subsection*{More information}
