+\author{\href{mailto:xuyuan.cn@gmail.com}{Yuan Xu}}
+\date{\today{}~(v0.7)}
+\maketitle
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\begin{abstract}
+  \texttt{pgf-umlsd} is a LaTeX package for drawing UML Sequence
+  Diagrams. As stated by its name, it is based on a very popular
+  graphic package \texttt{PGF/TikZ}. This document presents the usage
+  of \texttt{pgf-umlsd} and collects some UML sequence diagrams as
+  examples. \texttt{pgf-umlsd} can be downloaded from
+  \href{http://code.google.com/p/pgf-umlsd/}{http://code.google.com/p/pgf-umlsd/}.
+\end{abstract}
+
+\tableofcontents
+
+\section{The Essentials}
+\subsection{Basic graphics objects}
+\subsubsection{empty diagram}
+\demo{empty}
+
+\subsubsection{thread}
+\demo[0.3]{thread}
+
+\subsubsection{instance}
+\demo[0.3]{instance}
+
+\subsubsection{distance between threads and instances}
+\demo{distance}
+
+\subsubsection{customization}
+The package has two options for customization: \texttt{underline} and
+\texttt{rounded corners}, further customization see the example below:
+
+\demo{customize}
+
+
+\subsection{Call}
+\subsubsection{call}
+\demo[0.6]{call}
+
+\subsubsection{call self}
+\demo[0.6]{callself}
+
+\subsubsection{message call}
+\demo[0.6]{messcall}
+
+\subsubsection{nested call}
+\demo[0.6]{nested-call}
+
+\subsection{Message}
+\demo[0.6]{message}
+
+Sometimes however, it takes a considerable amount of time to reach the
+receiver (relatively speaking of course) . For example, a message
+across a network. Such a non-instantaneous message is drawn as a
+slanted arrow.
+
+\demo[0.6]{non-instantaneous-message}
+
+\subsection{Block}
+\demo[0.6]{block}
+
+\section{Manually adjustment}
+The idea of \texttt{pgf-umlsd} is users only have to write the logic
+of diagram, the program generates figure automatically. However, the
+package can not handle all the use case, it still needs to be adjusted
+manually.
+
+\subsection{Level}
+If the text on the arrows is more than one line (large function name
+for example) it will overlap other things. \texttt{postlevel} can be
+used to make the time (level) later.
+
+\demo[0.6]{postlevel}
+
+In the situation of multi-threads, some events happen at the same
+time. \texttt{prelevel} can make the call earlier.
+
+\demo[0.6]{prelevel}
+
+\subsection{Bias of thread line}
+In the situation of multi-threads, the instance cen be accessed at the
+same time (e.g. two threads reading data at the same time). Currently,
+we have to adjust the bias of thread line manually for this. Possible
+parameters for \texttt{setthreadbias} are: \texttt{center},
+\texttt{west} and \texttt{east}.
+
+\demo[0.8]{threadbias}
+
+\section{Examples}
+\subsection{Single thread}
+\example[0.8]{single-thread-example}
+
+\subsection{Multi-threads}
+\example[0.8]{multi-threads-example}
+
+\subsection{Annotation}
+\example[0.5]{sync-clock}
+
+\subsection{Known Issue}
+\texttt{pgf-umlsd} confilts with tikz \texttt{backgrounds} library.
+
