+\begin{frame}{Introduction}
+\begin{information}
+This Beamer theme is  a suitable theme for my use of Beamer in applied
+mathematics research.
+
+It meets my needs in my work. However, if you like this theme, and if you want
+to ask for or make improvements, don't hesitate to write to me !
+
+Obviously, we refer to the documentation of the Beamer class for details, and we
+will assume in this little documentation that the reader is familiar with the
+Beamer class.
+\end{information}
+
+\end{frame}
+
+
+\section{How to use it}
+
+\sepframe
+
+\begin{frame}[fragile]{How to use Amurmaple theme}
+  \begin{itemize}
+  \item The Amurmaple beamer theme consists in the file
+    \texttt{beamerthemeAmurmaple.sty} that you can put in your local
+    \texttt{\~{}/texmf/tex/latex/contrib/beamer-contrib/themes/beamer-amurmaple}
+    directory.
+  \item Simply add in your preamble\footnote{Note that the listing environments
+      of this document are not provided by Amurmaple theme.}
+    \begin{CodePreambule}
+\documentclass{beamer}
+\usetheme{Amurmaple}
+\end{CodePreambule}
+\item This theme depends on the following packages:
+  \begin{multicols}{2}
+  \begin{itemize}
+  \item \lstinline+tcolorbox+;
+  \item \lstinline+multicol+;
+  \item \lstinline+xparse+;
+  \item \lstinline+xfp+;
+  \item \lstinline+expl3+;
+  \item \lstinline+iftex+.
+  \end{itemize}
+\end{multicols}
+\end{itemize}
+\end{frame}
+
+\subsection{Theme Options}
+
+\begin{frame}[fragile]{Theme Options}
+  There are some options available :
+  \begin{description}
+  \item[nogauge:] that suppresses the gauge at the top of the vertical side bar
+    of the current slide ;
+  \item[nomail:] that suppresses the mail in the vertical side bar of
+    the current slide ;
+  \item[delaunay:] that produces a Delaunay mesh of random points in
+    the ``structure'' slides (title, section, etc.). \alert{This option can only be
+    used with \hologo{LuaLaTeX}} and depends on the
+  package~\lstinline{luamesh}\footfullcite{Luamesh};
+  \item[amurmapleblue:] that changes the main color (\lstinline+structure+) to a
+    certain blue (see slide~\ref{sl:color}) ;
+  \item[amurmaplegreen:] that changes the main color (\lstinline+structure+) to a
+    certain green (see slide~\ref{sl:color});
+  \end{description}
+  For example, these slides are produced with the following call\footnote{We use
+  the \texttt{charter} font family of \texttt{mathdesign}  with the serif Beamer theme.}:
+  \begin{CodePreambule}
+\usetheme[nomail,delaunay]{Amurmaple}
+  \end{CodePreambule}
+\end{frame}
+
+
+
+\section{Classical Beamer Tools}
+\sepframe
+\subsection{Colors}
+
+\begin{frame}[fragile, allowframebreaks]{Colors of the theme}
+  This theme provides some colors :
+  \begin{Code}
+\definecolor{AmurmapleRed}{rgb}{0.6,0.,0.}
+\definecolor{AmurmapleOrange}{RGB}{230,108,17}
+\definecolor{AmurmapleBlue}{RGB}{55,119,231}
+\definecolor{AmurmapleGreen}{rgb}{0.1,0.4,0.1}
+\end{Code}
+
+\textcolor{AmurmapleRed}{\lstinline+AmurmapleRed+} is used to redefine the \lstinline+structure+
+Beamer color\footnote{So if you redefine the \lstinline+structure+ color, the Amurmaple
+theme should change correctly.}, \textcolor{AmurmapleOrange}{\lstinline+AmurmapleOrange+} is used to redefine
+the \lstinline+text alerted+ Beamer color, \textcolor{AmurmapleGreen}{\lstinline+AmurmapleGreen+} is
+used for the math definition (see slide~\ref{sl:definition}) and for the
+\lstinline+block title example+ Beamer color, and the
+\textcolor{AmurmapleBlue}{\lstinline+AmurmapleBlue+} for the new environnement
+\lstinline+information+ (see slide~\ref{sl:information}).
+\framebreak
+
+\framesection{Color Theme Option}\label{sl:color}
+
+This theme provides two theme options to change the color settings:
+\begin{description}
+\item[amurmapleblue] that sets \texttt{AmurmapleBlue!80!black} as \texttt{structure}
+  color ;
+\item[amurmaplegreen] that sets \texttt{AmurmapleGreen!80!black} as \texttt{structure}
+  color.
+\end{description}
+In fact, internally, four colors are defined: \lstinline+Amurmaple@structure+,
+\lstinline+Amurmaple@alert+, \lstinline+Amurmaple@info+ and
+\lstinline+Amurmaple@example+.
+
+The color theme option is used as follow
+\begin{Code}
+  \usetheme[amurmapleblue]{amurmaple}
+\end{Code}
+\end{frame}
+
+\subsection{Classical commands}
+
+\begin{frame}[fragile]{Classical Beamer Commands}

+
+  \framesection{Quotation environment}
+
+  The environment \lstinline+\begin{quotation}[+\meta{author(s)}\lstinline+]...\end{quotation}+ has been
+  redefined allowing an optional argument to provide the author(s) of the
+  quotation.
+
+  \begin{quotation}[Donald E. Knuth, \emph{The \TeX book}]

+\sepframe
+
+\begin{frame}[fragile,allowframebreaks]{Title Page}
+  As shown in this document, the title page has been customized.
+  In addition to the classic commands for making the title page, the Amurmaple
+  theme provides new commands.
+
+  The new commands are :
+  \begin{itemize}
+  \item \lstinline+\mail+\marg{mail}: that is used to provide the mail. Without the theme option
+    \lstinline+nomail+, it is also added on the vertical side bar on the current
+    slide.
+  \item \lstinline+\webpage+\marg{webpage}: that is used to provide the personal webpage of
+    the speaker (or the project website).
+  \item \lstinline+\collaboration+\marg{collaboration(s)}: that is used to provide the collaborators
+    for the presented work.
+  \end{itemize}
+
+  \framebreak
+
+  Here the example used to generate this documentation.

+\end{frame}
+
+\section{New Frame Commands}
+
+\sepframe
+
+\begin{frame}[fragile]{\texttt{sepframe} command}
+\bigskip
+\begin{docCommand}{sepframe}{\oarg{title=\meta{mytitle},image=\meta{my image}}}
+The newcommand \lstinline+\sepframe+ is provided by the Amurmaple theme. This
+command allows you to generate a slide in the manner of a section page but with
+a slight improvement. In the red part below is generated the table of contents
+(with depth 1).
+
+Moreover, this command admits two optional arguments:
+\begin{description}
+\item[title:] this optional argument allows to modify the default title of the
+  frame (which is the current section name) ;
+\item[image:] this optional argument allows to add an image to the frame (no
+  image by default).
+\end{description}
+
+\end{docCommand}
+
+
+
+For exemple, we could use
+\begin{Code}
+\sepframe[title={My title},image={\includegraphics[width=5cm]{logo.png}}]
+\end{Code}
+
+The result is the next frame.
+\end{frame}
+
+\sepframe[title={My  title},image={\includegraphics[width=5cm]{logo.png}}]
+
+\begin{frame}[fragile]{\texttt{thanksframe} command}
+
+  \begin{docCommand}{thanksframe}{\marg{thanking message}}
+  The newcommand \lstinline+\thanksframe+ is provided by the Amurmaple
+  theme. This command allows you to generate a slide  to thank the audience.
+  The text written to thank is a mandatory argument (e.g. ``\emph{The end}'')
+  and the optional argument allows to change the default image which is the
+  \emph{title graphics} (\lstinline+\inserttitlegraphic+ exactly).
+\end{docCommand}
+The following code produces the next slide.
+  \begin{Code}
+\thanksframe{Merci beaucoup~!}
+  \end{Code}
+\end{frame}
+
+\thanksframe{Merci beaucoup~!}
+
+\section{New Commands and Environments}
+
+\begin{frame}[fragile,allowframebreaks]{Some New Commands and Environments}
+  The Amurmaple theme provides some other commands and environments.
+
+  \framesection{New Commands}
+
+  \begin{docCommand}{framesection}{\marg{text}}
+    Command to add a section title inside a frame.
+
+    The following example produced the previous frame sectioning \emph{New Commands}
+    \begin{Code}
+\framesection{New Commands}
+\end{Code}
+\end{docCommand}
+\begin{docCommand}{boxalert}{\marg{text}}
+Another \lstinline+\alert+ command with a colored box.
+  \begin{Exemple}
+\boxalert{This is another} command box to compare to \alert{this one}.
+  \end{Exemple}
+\end{docCommand}
+\framebreak
+
+\framesection{New Environments}
+{\itshape \structure{Note:} Each environment provided by the Amurmaple theme uses
+translations for title names. Hence, depending on the \texttt{babel} setting,
+\emph{Remark} becomes \emph{Remarque, Bemerkung,}\dots}
+
+\begin{docEnvironment}{information}{\oarg{changed title}}
+ The Amurmaple theme provides an information environment.\label{sl:information}
+  \begin{Code}
+\begin{information}
+  This is important information.
+\end{information}
+  \end{Code}
+  \begin{information}
+    This is an important information.
+  \end{information}
+
+  This environment has an optional argument to change the \emph{Information}
+  title.
+  \begin{Code}
+\begin{information}[More information]
+  Maybe more important information?
+\end{information}
+\end{Code}
+
+\begin{information}[More information]
+  Maybe more important information?
+\end{information}
+Because this environment is built with a \texttt{tcolorbox}, to use a footnote in it, you have to use \lstinline+\footnote[frame]{...}+.
+\end{docEnvironment}
+
+\begin{docEnvironment}{remark}{\oarg{title complement}}
+The Amurmaple theme provides a remark environment with an optional
+  argument to add a comment in the title (as for the theorem environment).
+  \begin{Code}
+\begin{remark}[Some complement]
+  This is a capital remark.
+\end{remark}
+\end{Code}
+\begin{remark}[Some complement]
+  This is a capital remark.
+\end{remark}
+
+Because this environment is built with a \texttt{tcolorbox}, to use a footnote in it, you have to use \lstinline+\footnote[frame]{...}+.
+\end{docEnvironment}
+
+\end{frame}
+
+\appendix
+
+\section{Appendix}
+
+\sepframe
+
+\begin{frame}[fragile]{Appendix}
+  In the appendix part of the document, (after the command
+  \lstinline+\appendix+) the display is slightly modified as you
+  can see in this slide. If the gauge exists, it disappears, the numbering
+  of slides is reset and the display is in roman form.
+\end{frame}
+
+
+\thanksframe{The end!}
