\maketitle

\section{Introduction (Header 1)}

This is some sample text for an introduction. This is a second sentence
that wraps to a new line. LaTeX will treat this all as one paragraph.

This is a new paragraph. It is separated from the previous paragraph by one empty line.

\subsection{This is a subsection (Header 2)}

Here we go!

\subsubsection{This is a subsubsection (Header 3)}

And that's as far as anyone should need to go.
