+\section{Introduction}
+
+Beamer is an awesome way to make presentations with LaTeX, but its theme
+selection is surprisingly sparse. The stock themes share an aesthetic that can
+be a little cluttered, while the few distinctive custom themes available are
+often specialized for a particular corporate or institutional brand.
+
+The goal of \themename is to provide a simple, modern Beamer theme suitable
+for anyone to use. It tries to minimize noise and maximize space for content;
+the only visual flourish it offers is an (optional) progress bar added to each
+slide or to the section slides.
+
+By default, \themename uses
+\href{https://www.mozilla.org/en-US/styleguide/products/firefox-os/typeface/}
+{Fira Sans}, a gorgeous typeface commissioned by Mozilla and designed by
+\href{http://www.carrois.com/fira-3-1/}{Carrois}. For best results, you will
+need the Fira typeface installed and use \XeLaTeX\ to typeset your slides.
+However, \themename can also be used with other typefaces and \LaTeX{} build
+systems.
+
+\themename's codebase is maintained on \href{https://github.com/matze/mtheme}
+{GitHub}. If you have issues, find mistakes in the manual or want to help make
+the theme even better, please get in touch there. The
+\href{https://github.com/matze/mtheme/graphs/contributors}
+{full list of contributors} already contains over a dozen names!
+
+
+\section{Getting Started}
+
+\subsection{Installing from CTAN}
+
+For most users, we recommend installing \themename from
+\href{https://www.ctan.org}{CTAN}. If you keep your \TeX\ distribution
+up-to-date, chances are good that \themename is already installed. If it is
+not, you need to update your packages. If your distribution is \TeX\ Live
+(or Mac\TeX\ on OS X), the following command updates all packages.
+
+\begin{lstlisting}
+tlmgr update --all
+\end{lstlisting}
+
+If this results in an error, you may need to run it with administrative privileges:
+
+\begin{lstlisting}
+sudo tlmgr update --all
+\end{lstlisting}
+
+Mac\TeX\ on OS X also provides a graphical interface for |tlmgr| called
+\TeX\ Live Utility.
+
+For any other distribution please refer to its documentation on how to update
+your packages.
+
+To get the most out of the theme you should also install the |Fira| fonts.
+However, this is not mandatory; \themename also works with the standard fonts.
+
+
+\subsection{Installing from GitHub}
+
+If you want to use the cutting-edge development version of \themename, you can
+install it manually. Like any \LaTeX\ package, this involves four easy steps:
+\begin{description}
+ \item[Download the source] with a |git clone| of the
+ \href{https://github.com/matze/mtheme}{\themename repository} or as a
+ \href{https://github.com/matze/mtheme/archive/master.zip}{zip archive}
+ of the latest development version.
+
+ \item[Compile the style files] by running |make sty| inside the downloaded
+ directory. (Or run \LaTeX{} directly on |source/metropolistheme.ins|.)
+
+ \item[Move the resulting |*.sty| files] to the folder containing your
+ presentation. To use \themename with many presentations, run
+ |make install| or move the |*.sty| files to a folder in your \TeX{} path
+ instead.
+
+ \item[Use the theme for your presentation] by declaring
+ |\usetheme{metropolis}| in the preamble of your Beamer document.
+\end{description}
+
+\themename uses the Make build system to offer the following installation
+options for advanced users:
+
+\begin{description}
+ \item[|make sty|] builds the theme style files.
+ \item[|make doc|] builds this documentation manual.
+ \item[|make demo|] builds a demo presentation to test the features of
+ \themename.
+ \item[|make all|] builds the theme and manual.
+ \item[|make clean|] removes the files generated by |make all|.
+ \item[|make install|] installs the theme into your local texmf folder.
+ \item[|make uninstall|] removes the theme from your local texmf folder.
+\end{description}
+
+
+\subsection{A Minimal Example}
+
+The following code shows a minimal example of a Beamer presentation using
+\themename.
+
+\begin{lstlisting}

+\title{A minimal example}
+\date{\today}
+\author{Matthias Vogelgesang}
+\institute{Centre for Modern Beamer Themes}
+\begin{document}
+ \maketitle
+ \section{First Section}
+ \begin{frame}{First Frame}
+ Hello, world!
+ \end{frame}
+\end{document}
+\end{lstlisting}
+
+
+\subsection{Dependencies}
+
+\themename depends on the |beamer| class and the following standard packages:
+\begin{multicols}{3}
+ \begin{itemize}
+ \item |tikz|
+ \item |pgfopts|
+ \item |etoolbox|
+ \item |calc|
+ \item |ifxetex|
+ \item |ifluatex|
+ \end{itemize}
+\end{multicols}
+
+For best results, we recommend installing the fonts
+\href{https://github.com/mozilla/Fira}{|Fira Sans|} and |Fira Mono|
+and compiling with \themename using \XeLaTeX\ or \LuaTeX.
+These are optional dependencies; \themename is compatible with (e.g.)
+pdf\LaTeX\ and will fall back to standard fonts if |Fira Sans| or |Fira Mono|
+is not installed.
+
+The packaged name of |Fira Sans| is |Fira Sans OT| in some Linux
+distributions; this case is automatically handled by \themename.
+
+
+\subsection{Pandoc}
+
+To use this theme with \href{http://johnmacfarlane.net/pandoc/}{Pandoc}-based
+presentations, you can run the following command
+
+\begin{lstlisting}
+$ pandoc -t beamer --latex-engine=xelatex -V theme:metropolis -o output.pdf input.md
+\end{lstlisting}
+
+
+\section{Customization}
+
+\subsection{Package options}
+
+The theme provides a number of options, which can be set using a key=value
+interface. The primary way to set options is to provide a comma-separated list
+of option-value pairs when loading \themename in the preamble:
+\begin{lstlisting}
+\usetheme[option1=value1, option2=value2, ...]{metropolis}
+\end{lstlisting}
+
+Options can be changed at any time --- even mid-presentation! --- with the
+|\metroset| macro.
+\begin{lstlisting}
+\metroset{option1=newvalue1, option2=newvalue2, ...}
+\end{lstlisting}
+
+The list of options is structured as shown in the following example.
+
+\DescribeOption{option key}{list of possible values}{default}{
+ A short description of the option.
+}
+
+
+\subsubsection{Main theme}
+
+\DescribeOption{titleformat}%
+ {regular, smallcaps, allsmallcaps, allcaps}
+ {regular}{
+ Changes the format of titles, subtitles, section titles, frame titles, and
+ the text on ``standout'' frames. The available options produce
+ Regular, \textsc{SmallCaps}, \textsc{\MakeLowercase{AllSmallCaps}}, or
+ \MakeUppercase{AllCaps} titles. Please refer to
+ Section~\ref{sec:titleformats} for known issues with these options.
+}
+
+\DescribeOption{titleformat plain}%
+ {regular, smallcaps, allsmallcaps, allcaps}%
+ {regular}{
+ Changes the format of ``standout'' frames (see |titleformat|, above).
+}
+
+
+\subsubsection{Inner theme}
+
+\DescribeOption{sectionpage}{none, simple, progressbar}{progressbar}{
+ Adds a slide at the start of each section (|simple|) with an optional thin
+ progress bar below the section title (|progressbar|). The |none| option
+ disables the section page.
+}
+
+\DescribeOption{subsectionpage}{none, simple, progressbar}{none}{
+ Optionally adds a slide at the start of each subsection. If enabled with
+ the |simple| or |progressbar| options, the style of the |section page| will
+ be updated to match the style of the |subsection page|. Note that section
+ slides and subsection slides can appear consecutively if both are enabled;
+ you may want to use this option together with |sectionpage=none| depending
+ on the section structure of your presentation.
+}
+
+
+\subsubsection{Outer theme}
+
+\DescribeOption{numbering}{none, counter, fraction}{counter}{
+ Controls whether the frame number at the bottom right of each slide is
+ omitted (|none|), shown (|counter|) or displayed as a fraction of the total
+ number of frames (|fraction|).
+}
+
+\DescribeOption{progressbar}{none, head, frametitle, foot}{none}{
+ Optionally adds a progress bar to the top of each frame (|head|),
+ the bottom of each frame (|foot|), or directly below each frame title
+ (|frametitle|).
+}
+
+\subsubsection{Color theme}
+\DescribeOption{block}{transparent, fill}{transparent}{
+ Optionally adds a light grey background to block environments like |theorem|
+ and |example|.
+}
+
+\DescribeOption{background}{dark, light}{light}{
+ Provides the option to have a dark background and light foreground instead
+ of the reverse.
+}
+
+
+\subsubsection{Font theme}
+
+\DescribeMacro{titleformat title}
+\DescribeMacro{titleformat subtitle}
+\DescribeMacro{titleformat section}
+\DescribeOption{titleformat frame}%
+ {regular, smallcaps, allsmallcaps, allcaps}%
+ {regular}{
+ Individually controls the format of titles, subtitles, section titles, and
+ frame titles (see |titleformat|, above).
+}
+
+
+\subsection{Color Customization}
+
+The included \themename color theme is used by default, but its colors can be
+easily changed to suit your tastes. All of the theme's styles are defined in
+terms of three beamer colors:
+\begin{itemize}
+ \item |normal text| (dark fg, light bg)
+ \item |alerted text| (colored fg, should be visible against dark or light)
+ \item |example text| (colored fg, should be visible against dark or light)
+\end{itemize}
+
+An easy way to customize the theme is to redefine these colors using
+
+\begin{lstlisting}
+\setbeamercolor{ ... }{ fg= ... , bg= ... }
+\end{lstlisting}
+in your preamble. For greater customization, you can redefine any of the other
+stock beamer colors. In addition to the stock colors the theme defines a number
+of \themename specific colors, which can also be redefined to your liking.
+
+\begin{lstlisting}
+\setbeamercolor{progress bar}{ ... }
+\setbeamercolor{title separator}{ ... }
+\setbeamercolor{progress bar in head/foot}{ ... }
+\setbeamercolor{progress bar in section page}{ ... }
+\end{lstlisting}
+
+
+\subsection{Font Customization}
+
+The default font for \themename is |Fira|. This can be easily changed using
+the standard font selection commands of the \textsf{fontspec} package. So if
+you prefer, for example, the \href{http://font.ubuntu.com}{|Ubuntu|} font family, just add the following two commands after loading the \themename theme.
+
+\begin{lstlisting}
+\setsansfont{Ubuntu}
+\setmonofont{Ubuntu Mono}
+\end{lstlisting}
+
+If you are expecting to present in a large room or with an underpowered
+projector, you may want to change the font to a heavier weight of Fira to
+maximize readability.
+
+\begin{lstlisting}
+\setsansfont[BoldFont={Fira Sans SemiBold}]{Fira Sans Book}
+\end{lstlisting}
+
+
+\subsubsection{Old style figures}
+
+The regular \textsf{fontspec} mechanism for changing glyph appearance applies
+also to this theme. If you want to have old style figures in the text but
+regular lined figures for math, you could add the following to your preamble:
+
+\begin{lstlisting}
+\usefonttheme{professionalfonts} % required for mathspec
+\usepackage{mathspec}
+\setsansfont[BoldFont={Fira Sans},
+ Numbers={OldStyle}]{Fira Sans Light}
+\setmathsfont(Digits)[Numbers={Lining, Proportional}]{Fira Sans Light}
+\end{lstlisting}
+
+
+\subsection{Commands}
+
+\subsubsection{Standout frames}
+
+The \themename inner theme offers a custom frame format with large, centered
+text and an inverted background --- perfect for focusing attention on
+single sentence or image. To use it, add the key |standout| to the frame:
+
+\begin{lstlisting}
+\begin{frame}[standout]
+ Thank you!
+\end{frame}
+\end{lstlisting}
+
+
+
+\section{\texttt{pgfplots} integration}
+
+\themename comes with a set of pre-defined pgfplots styles and a color theme
+based on Paul Tol's color scheme.
+
+
+\subsection{Styles}
+
+Pass the following style keys to the axis environment to get the appropriate
+effect:
+
+\begin{macro}{mlineplot}
+ Plot regular line charts with reduced axis frames, less intrusive legend and
+ subdued grid.
+\end{macro}
+\begin{macro}{mbarplot}
+ Plot vertical bar charts in a similar way as |mlineplot| but reduce grid usage.
+\end{macro}
+\begin{macro}{horizontal mbarplot}
+ Plot horizontal bar charts.
+\end{macro}
+\begin{macro}{disable thousands separator}
+ Helper style to remove thousands separator.
+\end{macro}
+
+
+\subsection{Paul Tol colors}
+
+A good presentation uses colors that are distinct from each other as much as
+possible as well as from black and white, can be discerned item under different
+lighting and display environments and by color-blind viewers, while matching
+well together.
+
+In a \href{https://personal.sron.nl/~pault/colourschemes.pdf}{technical note}
+for SRON, Paul Tol proposed a palette of colors satisfying these constraints.
+The sub-package |pgfplotsthemetol| defines palettes for |pgfplots| charts
+based on Tol's work.
+
+
+\section{Tips \& Tricks}
+
+\subsection{Backup Slides}
+
+Speakers will often include extra slides at the end of their presentation to
+refer to during audience questions. One easy 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.
+
+
+\section{Known Issues}
+
+\subsection{Title formats}
+\label{sec:titleformats}
+
+Be aware that not every font supports small caps, so the |smallcaps| or
+|allsmallcaps| options may not work if you use a font other than |Fira Sans|.
+In particular, the Computer Modern sans-serif typeface, which is used when
+\themename is compiled with pdf\LaTeX, does not have a small-caps variant.
+
+The title format options |allsmallcaps| and |allcaps| are quite nice from an
+aesthetic point of view, but their use of |\MakeLowercase| and
+|\MakeUppercase| can cause unexpected problems. For example:
+
+\begin{itemize}
+ \item Some commands, like |\\|, do not work inside |\MakeLowercase| and
+ |\MakeUppercase|. (See \href{https://github.com/matze/mtheme/issues/125}
+ {\#125})
+ \item Only alphabetic characters are affected by |\MakeLowercase|, so
+ numerals and punctuation remain at full height. This can spoil some of the
+ aesthetic benefits of |allsmallcaps|. (See
+ \href{https://github.com/matze/mtheme/issues/33}{\#33})
+ \item |\MakeLowercase| and |\MakeUppercase| apply to math mode and
+ |\scshape| does not. This can easily introduce mathematical errors that
+ are hard to catch.
+ \item It is impossible to typeset symbols which are encoded as uppercase
+ letters in a different font. In particular, |\mathbb| and |\mathcal|
+ letters will be replaced by other math glyphs. (See
+ \href{https://github.com/matze/mtheme/issues/153}{\#153})
+\end{itemize}
+
+The |allsmallcaps| and |allcaps| options are safe to use if your titles contain
+only alphabetic characters and do not require the expansion of any macros.
+
+
+\subsection{Interactions with other color themes}
+
+\themename can be used along with any other Beamer color theme, such as
+|crane| or |seahorse|. If you wish to do this, it is usually best to include
+the \themename subpackages individually so the \themename color theme is
+never loaded. This will prevent conflicts between the \themename color theme
+and your preferred theme.
+
+For example, overriding the color theme as follows may not work as expected because |\usetheme{metropolis}| loads the \themename color theme, which
+defines a relationship between the frametitle background and the primary
+palette of the theme. Since |seahorse| assumes a different relationship
+between its palettes, the result is a grey, rather than periwinkle,
+frametitle background.
+
+\begin{lstlisting}
+\usetheme{metropolis}
+\usecolortheme{seahorse}
+\end{lstlisting}
+
+The correct colors are chosen if the \themename outer, inner, and font themes
+are loaded seperately:
+
+\begin{lstlisting}
+\useoutertheme{metropolis}
+\useinnertheme{metropolis}
+\usefonttheme{metropolis}
+\usecolortheme{seahorse} % or your preferred color theme
+\end{lstlisting}
+
+Please note that \themename may not use all the colors defined in your
+favourite Beamer color theme. In particular, \themename does not set a
+background color for the title; this will cause issues when using color themes
+like |whale| which set a white foreground for the title.
+
+
+\subsection{Notes on second screen}
+
+If you use the |[show notes on second screen]| option built in to Beamer and
+compile with \XeLaTeX, text on slides following the first section slide may
+be rendered in white instead of the regular colour. This is due to
+\href{http://tex.stackexchange.com/questions/288408/}{a bug} in Beamer
+or \XeLaTeX\ itself. You can work around it either by compiling with \LuaTeX\
+or by adding the following code to your preamble to reset the text color
+on each slide.
+
+\begin{lstlisting}
+\makeatletter
+\def\beamer@framenotesbegin{% at beginning of slide
+ \usebeamercolor[fg]{normal text}
+ \gdef\beamer@noteitems{}%
+ \gdef\beamer@notes{}%
+}
+\makeatother
+\end{lstlisting}
+
+
+\subsection{Standout frames with labels}
+
+Because the |standout| frame option creates a group to restrict the colour
+change to a single slide, labels defined after calling |standout| will stay
+local to the group. In other words, the following may result in a ``label undefined'' error.
+
+\begin{lstlisting}
+\begin{frame}[standout, label=conclusion]{Conclusion}
+ Awesome slide
+\end{frame}
+\end{lstlisting}
+
+To fix this problem, change the order of the keys in the frame.
+
+\begin{lstlisting}
+\begin{frame}[label=conclusion, standout]{Conclusion}
+ Awesome slide
+\end{frame}
+\end{lstlisting}
+
+This error can be unwittingly triggered if you export your slides from Emacs
+Org mode, which automatically adds labels after frame options. Alex Branham
+\href{https://github.com/matze/mtheme/issues/203}{offers} the following
+solution for Org mode users, using |org-set-property|.
+
+\begin{lstlisting}
+* Start of a frame
+ :PROPERTIES:
+ :BEAMER_opt: label=conclusion,standout
+ :END:
+\end{lstlisting}
+
+
+\subsection{Standout frames with Pandoc}
+
+With Pandoc versions prior 1.17.2 it was not possible to create standout frames
+because Pandoc only supported a specific list of frame attributes thus ignoring
+additional attributes such as |{.standout}|.
