+  \maketitle
+  \LaTeX{} is a document preparation system for the \TeX{}
+  typesetting program. It offers programmable desktop publishing
+  features and extensive facilities for automating most aspects of
+  typesetting and desktop publishing, including numbering and
+  cross-referencing, tables and figures, page layout, bibliographies,
+  and much more. \LaTeX{} was originally written in 1984 by Leslie
+  Lamport and has become the dominant method for using \TeX; few
+  people write in plain \TeX{} anymore. The current version  is
+  \LaTeXe.
+ 
+  % This is a comment; it will not be shown in the final output.
+  % The following shows a little of the typesetting power of LaTeX:
+  \begin{align}
+    E &= mc^2                              \\
+    m &= \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}
+  \end{align}
