\section{Introduction}
%==============================================
\begin{frame}{\insertsectionhead}
\framesubtitle{A short introduction to Trigon}
\themename is a modern, elegant and versatile theme for Beamer, inspired by
the
\href{https://github.com/matze/mtheme}{\textsc{metropolis} theme} from Matthias
Vogelgesang.
\vfill
\themename comes with lots of nice extra features
\begin{itemize}
\item Multiple style variations for title, section and normal slides
\item Simple customization of theme colors
\item Lots of convenient options to tweak the design
\end{itemize}
\end{frame}
%==============================================
\section{Layout}
%==============================================
\subsection{Layout variations}
\begin{frame}[fragile=singleslide]{\insertsectionhead}
\framesubtitle{\insertsubsectionhead}
The general style for the title, section and regular frames can be changed
easily with simple options. Here are some examples for the title page
\begin{figure}[ht!]
\begin{subfigure}[b]{0.3\textwidth}
\frame{\includegraphics[width=\textwidth]{screenshots/layout_example-03.jpg}}

\end{subfigure}

\subsection{Fonts}
\begin{frame}
\frametitle{\insertsectionhead}
\framesubtitle{\insertsubsectionhead}
This theme is using \textit{Source Sans Pro} font for all elements by default.
This can be disabled by providing the option \texttt{usesourcefonts=false}.
\vfill
Emphasis can be added by using \textbf{bold} typeface, \textit{italic},
\alert{alert} or {\color{tPrim}{simple colors}}.
\vfill
Equations are typeset with this font as well
\begin{equation*}
F(x|\mu,s) = \int_{-\infty}^x s^{-1}\left(1+e^{-\frac{v-\mu}{s}}\right)^{-2} e^{-\frac{v-\mu}{s}}\;\mathsf{d}v = \frac{1}{1+e^{-\frac{x-\mu}{s}}}
\end{equation*}

Use the theme color \texttt{tPrim}, \texttt{tSec}, \texttt{tGrey} and

\appendix
\begin{frame}[fragile]{Backup slides}
Sometimes, it is useful to add slides at the end of your presentation to
refer to during audience questions.
The best way to do this is to include the \verb|appendixnumberbeamer|
package in your preamble and call \verb|\appendix| before your backup slides.
\themename will automatically turn off slide numbering and progress bars for
slides in the appendix.
