\section{Introduction}

\begin{frame}{What is Beamer?}
	The beamer classes for \LaTeX\ are used to create presentations that are to be shown with a beamer. The text typesetting system creates PDF files that can be shown by a large number of programmes.
	
	The present theme was adapetd from HSRM theme by Benjamin Weiss and it makes the creation of slides (assuming basic knowledge of \LaTeX\ ) child's play.
\end{frame}

\begin{frame}{System requirements}
	In order to successfully create presentations with this theme, the following requirements must be met by the system:
	\begin{itemize}
		\item LuaLaTeX must be used to typeset the slides.
		\item Besides some standard packages, the packages \texttt{beamer}, \texttt{pgf} and \texttt{xcolor} must be installed.
		\item The fonts \quoted{Flama-Light}, \quoted{Flama-Book} and \quoted{Flama-Medium} should be installed. Alternative: \quoted{Arial}\\\url{http://www.felicianotypefoundry.com/}
	\end{itemize}
\end{frame}

\section{Tutorial}
\begin{frame}[containsverbatim]{Basic structure of the document}
The basic structure is simple:
\begin{lstlisting}
\documentclass[compress]{beamer}
% Theme
\usetheme{sleek}
% General presentation settings 
\title{Presentation title}
\subtitle{Subtitle of the presentation}
\author{Your name}
\institute{Study area\University {\Medium RheinMain}}
\begin{document}
%Slides
\end{document}
\end{lstlisting}
\end{frame}

\begin{frame}{Theme options}
To customise the presentation, the following options can be selected.
\begin{table}[]
	\begin{tabularx}{\linewidth}{l>{\raggedright}X}
		\toprule
		\textbf{Option} & \textbf{Effect} \tabularnewline
		\midrule
		\texttt{noflama} & If you do not have the Flama font you can switch to the Arial font with this option. \tabularnewline
		\texttt{noserifmath} & Formulas are also set sans serif. \tabularnewline
		\texttt{nosectionpages} & The section introduction pages will be hidden.\tabularnewline
		\bottomrule
	\end{tabularx}
	\label{tab:options}
\end{table}
\end{frame}

\begin{frame}{Primary colours}

\end{frame}

\begin{frame}[containsverbatim]{slide structure}
Structure in Beamer is the same as in \LaTeX\ using \lstinline!section!, \lstinline!subsection!, etc. For slides the \lstinline!frame! environment is defined.

The slide title can be passed directly to the \lstinline!frame! environment or set within the environment using \lstinline!\frametitle{slide title}!
\begin{lstlisting}
\section{My Section}
\subsection{My Subsection}
\begin{frame}
\frametitle{slide title}
% slide content
\end{frame}
\end{lstlisting}
\end{frame}

\begin{frame}[containsverbatim]{title page and table of contents}
The title page is created with 
\begin{lstlisting}
\maketitle
\end{lstlisting}
And the table of contents with
\begin{lstlisting}
\begin{frame}{outline}
	\tableofcontents[hideallsubsections]
\end{frame}
\end{lstlisting}
The option \lstinline!hideallsubsections! is useful for longer presentations to keep the table of contents compact.
\end{frame}

\subsection{Enumerations}
\begin{frame}[containsverbatim]{enumerations}
Enumerations are possible with the \lstinline!enumerate! and the \lstinline!itemize! environment.
\begin{enumerate}
	\item item 1
	\item item 2
	\begin{itemize}
		\item point 1
		\item point 2
	\end{itemize}
	\item point 3
\end{enumerate}
\end{frame}

\subsection{Emphasis}
\begin{frame}[containsverbatim]{emphasis}
In the Beamer class, the function \lstinline!\alert! is defined to highlight individual words. Example:
\begin{itemize}
	\item \alert{highlighted text}
\end{itemize}
Additionally, \lstinline!\quoted! and \lstinline!\doublequoted! can be used, resulting in the following outputs:
\begin{itemize}
	\item[] \quoted{single quotation marks}
	\item[] \doublequoted{Double quotation marks}
\end{itemize}
\end{frame}

\subsection{Block structures}
\begin{frame}[containsverbatim]{Simple block with enumeration}
Block environments are defined in Beamer for structuring purposes.
\begin{block}{Block with an enumeration}
	\begin{itemize}
		\item point 1
		\item point 2
	\end{itemize}
\end{block}
\begin{lstlisting}
\begin{block}{block with a bullet}
	\begin{itemize}
		\item point 1
		\item point 2
	\end{itemize}
\end{block}
\end{lstlisting}
\end{frame}

\begin{frame}[containsverbatim]{Alert Block}
\begin{alertblock}{Alert Block}
	An Alert Block is coloured with the first primary colour.
\end{alertblock}
\begin{lstlisting}
\begin{alertblock}{alert block}
An Alert Block is coloured with the first primary colour.
\end{alertblock}
\end{lstlisting}
\end{frame}

\begin{frame}[containsverbatim]{Example Block}
\begin{exampleblock}{Example Block}
	An Example Block is coloured with the first secondary colour.
\end{exampleblock}
\begin{lstlisting}
\begin{exampleblock}{Example Block}
An example block is coloured with the first secondary colour.
\end{exampleblock}
\end{lstlisting}
\end{frame}

\begin{frame}[containsverbatim]{block with other colour}
\begingroup
\setbeamercolor{block title}{bg=sleekSec2Dark}
\setbeamercolor{block body}{fg=white,bg=sleekSec2}
\begin{block}{Block with other colour}
	Another secondary colour is used in this block.
\end{block}
\endgroup
\begin{lstlisting}
\begingroup
\setbeamercolor{block title}{bg=sleekSec2Dark}
\setbeamercolor{block body}{bg=sleekSec2}
\begin{block}{block with other colour}
