\section{Loading}
In the preamble only the package \Pack{mdframed} width the option \Opt{framemethod=\Loadedframemethod} is loaded. All other modifications will be done by \Cmd{mdfdefinestyle} or \Cmd{mdfsetup}.

{\large\color{red!50!black}
\NOTE Every \Cmd{global} inside the examples is necessary to work with the package \Pack{showexpl}.}

\section{Examples}
All examples have the following settings:
