+\section{The Elsevier article class}\label{the-elsevier-article-class}
+
+\paragraph{Installation}\label{installation}
+
+If the document class \emph{elsarticle} is not available on your
+computer, you can download and install the system package
+\emph{texlive-publishers} (Linux) or install the LaTeX~package
+\emph{elsarticle} using the package manager of your TeX~installation,
+which is typically TeX~Live or MikTeX.
+
+\paragraph{Usage}\label{usage}
+
+Once the package is properly installed, you can use the document class
+\emph{elsarticle} to create a manuscript. Please make sure that your
+manuscript follows the guidelines in the Guide for Authors of the
+relevant journal. It is not necessary to typeset your manuscript in
+exactly the same way as an article, unless you are submitting to a
+camera-ready copy (CRC) journal.
+
+\paragraph{Functionality}\label{functionality}
+
+The Elsevier article class is based on the standard article class and
+supports almost all of the functionality of that class. In addition, it
+features commands and options to format the
+
+\begin{itemize}
+\item
+  document style
+\item
+  baselineskip
+\item
+  front matter
+\item
+  keywords and MSC codes
+\item
+  theorems, definitions and proofs
+\item
+  lables of enumerations
+\item
+  citation style and labeling.
+\end{itemize}
+
+\section{Front matter}\label{front-matter}
+
+The author names and affiliations could be formatted in two ways:
+
+\begin{enumerate}
+\def\labelenumi{(\arabic{enumi})}
+\item
+  Group the authors per affiliation.
+\item
+  Use footnotes to indicate the affiliations.
+\end{enumerate}
+
+See the front matter of this document for examples. You are recommended
+to conform your choice to the journal you are submitting to.
+
+\section{Bibliography styles}\label{bibliography-styles}
+
+There are various bibliography styles available. You can select the
+style of your choice in the preamble of this document. These styles are
+Elsevier styles based on standard styles like Harvard and Vancouver.
+Please use BibTeX~to generate your bibliography and include DOIs
+whenever available.
+
+Here are two sample references: Feynman and Vernon Jr. (1963; Dirac
+1953).
