+# Manifest for gotham
+
+This file is a listing of all files considered to be part of this package.
+It is automatically generated with `l3build manifest`.
+
+
+## Repository manifest
+
+The following groups list the files included in the development repository of the package.
+Files listed with a ‘†’ marker are included in the TDS but not CTAN files, and files listed
+with ‘‡’ are included in both.
+
+### Source files
+
+These are source files for a number of purposes, including the `unpack` process which
+generates the installation files of the package. Additional files included here will also
+be installed for processing such as testing.
+
+* gotham.dtx ‡
+* gotham.ins ‡
+* gotham-logo.pdf ‡
+* gotham-layout.pdf ‡
+* gotham-blueprint.pdf ‡
+* gotham-safetybox.pdf ‡
+
+### Text files
+
+Plain text files included as documentation or metadata.
+
+* MANIFEST.md ‡
+* README.md ‡
+
+### Derived files
+
+The files created by ‘unpacking’ the package sources. This typically includes
+`.sty` and `.cls` files created from DocStrip `.dtx` files.
+
+* beamercolorthemegotham.sty †
+* beamerfontthemegotham.sty †
+* beamerinnerthemegotham.sty †
+* beamerouterthemegotham.sty †
+* beamerthemegotham.sty †
+* gotham-blueprint.pdf ‡
+* gotham-layout.pdf ‡
+* gotham-logo.pdf ‡
+* gotham-safetybox.pdf ‡
+
+### Support files
+
+These files are used for unpacking, typesetting, or checking purposes.

+* gotham-logo.png 
+* gotham-test-035-a.png 
+* gotham-test-035-b.png 
+
+### Test files
+
+These files form the test suite for the package. `.lvt` or `.lte` files are the individual
+unit tests, and `.tlg` are the stored output for ensuring changes to the package produce
+the same output. These output files are sometimes shared and sometime specific for
+different engines (pdfTeX, XeTeX, LuaTeX, etc.).

+## What is Gotham ?
+This `Gotham` package is a modern, minimal-ish, versatile and extendable theme for your `Beamer` presentations using `LaTeX(3)`.
+
+
+## Table of Contents
+[[_TOC_]]
+
+
+## Why this package ?
+ONCE UPON THE TIME, I was adapting `Metropolis` Beamer theme to get my institutional templates.
+Indeed, `Metropolis` Beamer theme is a great work that is very convenient and well appreciated by many. 
+
+BUT, `Metropolis` seems not maintained anymore and is not flexible enough.
+Moreover, `Metropolis` (or its successor initiative Moloch) and Beamer in some extends are not very flexible. 
+For example, it requires cumbersome modifications to apply a different background for your section frames.
+
+SO, `Gotham` tries to bring that kind of flexibility and `LaTeX3` implementation on top of the good-looking `Metropolis` theme.
+
+
+## See it in action
+Here are some screenshot of what you can obtain:
+
+<img src="support/gotham-example169transp-1.png" width="700">
+
+<img src="support/gotham-example43dark-1.png" width="700">
+
+An `pdf` example/demo result is available [here](https://gitlab.com/RomainNOEL/beamertheme-gotham/-/artifacts/), and the `tex` source file to build it is available [here](/examples/section-Gotham.tex).
+
+The following code shows a **minimal example** of a Beamer presentation using Gotham.
+```latex
+\documentclass{beamer}
+\usetheme{gotham}
+\title{A minimal example}
+\date{\today}
+\author{Romain NOEL}
+\institute{Centre for Modern Beamer Themes}
+\begin{document}
+  \maketitle
+  \section{First Section}
+  \begin{frame}{First Frame}
+    Hello, world!
+  \end{frame}
+\end{document}
+```
+is yielding the following:
+
+<img src="support/gotham-exampleSimple-1.png" width="700">
+
+
+## Some of the features included
+- `l3build` a build system for LaTeX that unpack the sources, build the documentation and examples, run unit tests, check tags, prepare for CTAN publishing, etc...
+- `expl3`
+- dark, light and transparent theme
+- can adapt to 16:9 and 4:3 screen format
+- progress bar
+- **can mix** themes
+
+
+## Documentation
+The complete `pdf` documentation can be found through an [artefact](https://gitlab.com/RomainNOEL/beamertheme-gotham/-/artifacts/).
+
+
+## How to install ?
+Several possibilities are available and tested: 
+- download the `.sty` released zip files,
+- build from sources using `l3build`,
+- download or update from [CTAN](https://ctan.org/pkg/beamertheme-gotham),
+- fork a example from [Overleaf](https://overleaf.com) .
+
+### Download from release
+The zip file containing the `.sty` files is downloadable through our latest [release link](https://gitlab.com/RomainNOEL/beamertheme-gotham/-/releases/)
+
+### Build from sources
+You can also install the theme from sources, in which case you need a working LaTeX installation with `l3build` installed. 
+Then just follow these steps:
+```bash
+git clone https://gitlab.com/RomainNOEL/beamertheme-gotham.git
+cd beamertheme-gotham
+l3build install
+```
+
+Additionally you can use the other `l3build` target:
+- `l3build unpack` builds the theme style files.
+- `l3build doc` builds this documentation manual and the examples.
+- `l3build check` builds the theme and manual.
+- `l3build install` installs the theme into your local texmf folder.
+- STOP unless you want remove it.
+- `l3build uninstall` removes the theme from your local texmf folder.
+- `l3build clean` removes the files generated by `l3build`.
+
+### Download from CTAN
+The CTAN repository is available through the Gotham [package](https://ctan.org/pkg/beamertheme-gotham), so you can install it using your favorite LaTeX package manager. For example, with `tlmgr`:
+```bash
+tlmgr install beamertheme-gotham
+```
+
+### Fork from Overleaf example
+If you want to play with it before installing, you can fork this [Overleaf project](https://overleaf.com) and have fun.
+
+
+## License
+The LaTeX Project Public License [(LPPL)](/LICENSE.txt)
+
+
+## Project status
+The status of the project is "maintained".
+However, if you have a bit of free time and good will to help the maintenance, it will be very appreciated and welcomed.

+\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; some visual flourishes are offered as options.
+
+	The final product provides a modern, elegant and versatile theme with a	high degree of customization.
+	So it can easily be used to build a particular corporate or institutional brand theme on top of it.
+ 
+	The implementation of this theme is strongly inspired from the excellent \href{https://github.com/matze/mtheme}{\textsc{Metropolis}} theme by Matthias Vogelgesang, from which it borrows numerous options.
+	\themename's codebase lives on
+	\href{https://gitlab.com/RomainNOEL/beamertheme-gotham} {Gitlab}.
+	\newline
+	If you have issues, find mistakes in the manual or want to help make the theme even better, please get in touch there.
+	Any feature request, issue report or merge requests are welcome.
+
+
+%% ------------------------------------
+\section{Getting Started}
+\subsection{Installing from CTAN}
+	The latest stable version of \themename is available on
+	\href{https://ctan.org/pkg/beamertheme-gotham}{CTAN} and should now be part of the usual \TeX\ distributions (\TeX\ Live, Mac\TeX\ , Mik\TeX\ ), under the name	\textit{beamertheme-gotham}. 
+	It means that if your distribution is kept up-to-date, the package should normally be already installed on your system. 
+	If this is not the case, consider updating the packages of your Tex distribution.
+
+	For \TeX\ Live and Mac\TeX\ users, this usually means running
+	\begin{lstlisting}
+		tlmgr update --all
+	\end{lstlisting}
+	or if administrative privileges are required
+	\begin{lstlisting}
+		sudo tlmgr update --all
+	\end{lstlisting}
+
+	For Mik\TeX\ users, please refer to \href{https://miktex.org/howto/update-miktex}{the official Mik\TeX\ documentation}.
+
+
+\subsection{Installing from Gitlab}
+	If you want to use the cutting-edge development version of \themename, you can install it manually by following these steps:
+	\begin{description}
+		\item[Download the source] from
+			\href{https://gitlab.com/RomainNOEL/beamertheme-gotham}{\themename repository}
+			using |git clone| or as a 
+			\href{https://gitlab.com/RomainNOEL/beamertheme-gotham/-/archive/master/beamertheme-gotham-master.zip}{zip archive} 
+			of the latest development version.
+		\item[Compile the style files] by running |l3build unpack| inside the downloaded	directory. 
+			(Or run \LaTeX{} directly on |source/gothamtheme.ins|.)
+		\item[Move the resulting |*.sty| files] to the folder containing your presentation. 
+			To use \themename with many presentations, run
+			|l3build install| or move the |*.sty| files to a folder in your \TeX{} path instead.
+		\item[Use the theme] by declaring \lstinline|\usetheme{gotham}| in the preamble of your document.
+	\end{description}
+
+	\themename uses the l3build system to offer the following installation options for advanced users:
+	\begin{description}
+		\item[|l3build unpack|] builds the theme style files.
+		\item[|l3build doc|] builds this documentation manual and the examples.
+		\item[|l3build check|] builds the theme and manual.
+		\item[|l3build clean|] removes the files generated by |l3build|.
+		\item[|l3build install|] installs the theme into your local texmf folder.
+		\item[|l3build uninstall|] removes the theme from your local texmf folder.
+	\end{description}
+
+
+% \subsection{Overleaf}
+% 	\themename is therefore automatically supported for new documents. 
+% 	If you want to switch older documents to use the \themename theme, you need to \href{https://www.overleaf.com/blog/new-feature-select-your-tex-live-compiler-version}{select
+% 	TexLive 2021 or higher as your TeX Live version} (this may cause issues with other packages used in your presentation).
+
+% 	In addition to that, a template project was created and is publicly available in the \href{https://www.overleaf.com/latex/templates/gotham-beamer-theme/wjyyzvdzqkgf}{Overleaf Gallery} to bootstrap your presentation.
+
+
+%% ------------------------------------
+\subsection{A Minimal Example}
+	The following code shows a minimal example of a Beamer presentation using \themename, and the output generated is given on \cref{fig-minimal}.
+
+	\begin{lstlisting}
+		\documentclass{beamer}
+		\usetheme{gotham} % Loads Gotham theme
+		\title{A minimal example}
+		\subtitle{using Gotham theme}
+		\date{\today}
+		\author{John DOE}
+		\institute{Your university or company}
+		
+		\begin{document}
+			\maketitle
+			\section{First Section}
+			\begin{frame}{First Frame}
+				Hello world !
+			\end{frame}
+		\end{document}
+	\end{lstlisting}
+
+	\begin{figure}[htp]
+		\centering
+		\fbox{\includegraphics[width=0.7\textwidth]{gotham-exampleSimple.pdf}}
+		\caption{A simple example.}
+		\label{fig-minimal}
+	\end{figure}
+
+
+\subsection{Dependencies}
+	\themename depends on the |beamer| class and the following standard packages:
+	\begin{itemize}
+		\item |tikz|
+		\item |expl3|
+		\item |xfp|
+		\item |etoolbox|
+		\item |ifxetex|
+		\item |ifluatex|
+	\end{itemize}
+
+	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.
+
+
+%% ------------------------------------
+\section{Customization}
+\subsection{Package options}
+	\themename 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}[gobble=2]
+		\usetheme[option1=value1, option2=value2, ...]{gotham}
+	\end{lstlisting}
+
+	Options can be changed at any time --- even mid-presentation ! --- with the |\gothamset| command.
+	\begin{lstlisting}[gobble=2]
+		\gothamset{option1=newvalue1, option2=newvalue2, ...}
+	\end{lstlisting}
+
+	The list of options is structured as shown in the following example.
+
+	\begin{DescribeGothamOption}{option key}
+	{list of possible values}{default}
+		A short description of the option.
+	\end{DescribeGothamOption}
+
+	As \themename implementation is heavily inspired from the excellent
+	\href{https://github.com/matze/mtheme}{\textsc{Metropolis}} theme by Matthias	Vogelgesang, many of \textsc{Metropolis} options are also available in \themename.

+\subsubsection{Color theme}
+	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 a few main colors:
+	\begin{itemize}
+		\item |colorA| The primary theme color, used for frametitle, standout and text if the appropriate options are selected.
+	\end{itemize}
+
+	An easy way to customize the theme is to redefine these colors using:
+	\begin{lstlisting}
+		\colorlet{colorPale}{gPaleYell} % BG in light/normal mode
+		\colorlet{colorDark}{gDarkBlack} % FG in light/normal mode
+		\colorlet{colorA}{gDarkTeal} % frametitle, standin.out,
+		\colorlet{colorAreversed}{gLightTeal} % frametitle, standin.in,
+		\colorlet{colorB}{gMidGrey} % gray BG : progress bar, blocks
+		\colorlet{colorC}{gDeepYellOr} % progress bar
+		\colorlet{colorD}{gLightOrange} % alert
+		\colorlet{colorE}{gLightGreen} % example
+	\end{lstlisting}
+
+	\begin{DescribeGothamOption}{background}{light, dark, transparent}{transparent}{
+		Controls weather the color of all headings (title page, frame title, etc.)	should be in black (|default|) or in a slightly darker shade of the theme color |theme|.
+	}\end{DescribeGothamOption}
+
+	\begin{DescribeGothamOption}{colorset}
+	{red, anthracite}{anthracite}{% blue, green, orange, teal, 
+		Predefined set colors (|colorA, colorB, ...|) leading to different ambiances.
+	}\end{DescribeGothamOption}
+
+	\begin{DescribeGothamOption}{block}{native, transparent, fill}{native}{
+		Optionally adds a light grey background to block environments like |theorem| and |example|.
+	}\end{DescribeGothamOption}

+
+\subsubsection{Inner theme}
+	\begin{DescribeGothamOption}{title page}
+	{gotham~normal, gotham~reversed, gotham~dividedpic, gotham~splitvert, <your-name>}{gotham~normal}{
+		By setting this option you can change the title page according predefined style or even set your own template.		
+		If you want to use your own template, this latter should be previously defined with:

+\subsection{Frame options}
+	Frame options are affecting the templates used on the current frame through the following syntax:
+	\begin{lstlisting}
+		\begin{frame}[option] ... \end{frame}
+	\end{lstlisting}
+	Below a description of the different frame options brought by \themename{}.
+
+	\DescribeOption{noBGC}
+		Apply an empty |background canvas| template.
+
+	\DescribeOption{watermark}
+	\DescribeOption{nowatermark}
+		Apply (with |watermark|) or deactivated (|nowatermark| when \lstinline|\gothamset{watermark default=on}| was given) the |background| template, through %\\
+		\lstinline|\defbeamertemplate{background}{watermark/<your-name>}{<your-def>}| and %\\
+		\lstinline|\gothamset{watermark template=<your-name>}|.
+
+	\DescribeOption{standout}
+	\DescribeOption{standin}
+		Apply the |standin| (and |standout| respectively) templates through the definition
+		\lstinline|\defbeamertemplate{standin}{<your-name>}{<your-def>}| and the option \lstinline|\gothamset{standin template=<your-name>}|.
+
+	\DescribeOption{toc}
+		Appy the |toc| template defined by \lstinline|\gothamset{tocframe template=<your-name>}|.
+
+	\DescribeOption{edging}
+	\DescribeOption{noedging}
+		Apply (with |edging|) or deactivated (|noedging| when \lstinline|\gothamset{edging default=on}| was given) the |sidebar canvas left| (and right respectively) template, through 
+		\lstinline|\defbeamertemplate{sidebar canvas left}{default/<your-name>}{<your-def>}| (and right)
+		and the option 
+		\lstinline|\gothamset{sidebar canvas left template=<your-name>}| (and right).
+
+	\DescribeOption{nologo}
+	\DescribeOption{nofootline}
+	\DescribeOption{nofooter}
+		Apply empty |logo| (and |footline|, |footer| respectively) templates. 
+		This can be convenient when extra space is needed.
+		\vspace{1em}
+
+	\DescribeOption{rotateFooter}
+	\DescribeOption{noRotateFooter}
+		Enable or disable the rotation of the elements in the |footer|.
+		This can be convenient when extra space is needed in 16/9 mode especially.
+
+	\DescribeOption{part}
+	\DescribeOption{section}
+	\DescribeOption{subsec}
+	\DescribeOption{subsubsec}
+		Apply \lstinline|\usebeamertemplate{part frame}|, (|section frame|, |subsection frame| and |subsubsection frame| respectively) templates.
+		This makes more sense for internal use, but can be reused everywhere else.
+		\vspace{2em}
+
+	\DescribeOption{tocpart}
+	\DescribeOption{tocsec}
+	\DescribeOption{tocsubsec}
+	\DescribeOption{tocsubsubsec}
+		Apply \lstinline|\usebeamertemplate{toc part frame}|, (|toc section frame|, |toc subsection frame| and |toc subsubsection frame| respectively) templates.
+		This makes more for internal use, but can be reused everywhere else.
+		\vspace{1em}
+
+
+%% ------------------------------------
+\subsection{Commands for Customization}
+	\themename{} defines some commands that can be used as hooks, ie., that can be redefined when needed.
+
+	\begin{function}{\gothamInstituteLogoCircle[1][4ex]}
+		\begin{arguments}
+			\item |height| of the picture. 
+		\end{arguments}
+		Command to include the circular logo of your institute in the frametitle when using \lstinline|\gothamset{progressbar position=circlehead}|.
+		For example, you redefine this command through:
+		\begin{lstlisting}[gobble=6]
+			\renewcommand{\gothamInstituteLogoCircle}[1][4ex]{
+				\includegraphics[height=#1]{<your-logo-circular>}
+			}
+		\end{lstlisting}
+	\end{function}
+
+	\begin{function}{\gothamInstituteLogoSquare[1][4ex]}
+		\begin{arguments}
+			\item |height| of the picture. 
+		\end{arguments}
+		Command to include the circular logo of your institute in the frametitle.
+		For example, you redefine this command through:
+		\begin{lstlisting}[gobble=6]
+			\renewcommand{\gothamInstituteLogoSquare}[1][4ex]{
+				\includegraphics[height=#1]{<your-logo-square>}
+			}
+		\end{lstlisting}
+	\end{function}
+
+	\begin{function}{\gothamFrameSubtitleSep}
+		Command defining the separator used between the frametitle and the subtitle.
+	\end{function}
+
+	\begin{function}{\gothamRightFiligrane, \gothamLeftFiligrane}
+		Commands that are used by default in the |sidebar canvas right| (and left).
+		This avoids the redefinition of the whole templates, especially since the |sidebar canvas right| is containing elements by default in Beamer theme (like the |logo|).
+	\end{function}
+
+
+\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 also applies 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{Backgrounds available}
+% 	xx
+
+
+\subsection{Length Customization}
+	\begin{variable}{\sectionhoffset} 
+		length controlling the horizontal offset of the (section title + progress bar) block. 
+		Can be useful when extra stuff wants to be displayed on sides of the block.
+		The default value is 0pt.
+	\end{variable}
+
+	\begin{variable}{\sidebarRightHOffset, \sidebarLeftHOffset} 
+		Length controling the horizontal and vertical offset in order to position |\gothamRightFiligrane| (respectively |\gothamLeftFiligrane|) when using the default sidebar canvas (right and left) from \themename.
+	\end{variable}
+	
+	\begin{variable}{\gothamHposLeftRotFooter, \gothamHposRightRotFooter, \gothamVposLeftRotFooter, \gothamVposRightRotFooter} 
+		length controlling the horizontal and vertical positioning of the left and right elements of the rotated footer.
+	\end{variable}
+	
+	\begin{variable}{\gothamFootlineRuleLeftPadding} 
+		length controlling the horizontal space between the left border of the page and the left side of the rule.
+	\end{variable}
+	
+	\begin{variable}{\gothamFootlineRuleHeight, \gothamFootlineRuleLength} 
+		Dimensions controlling the height and the length of the rule used to delimit the footer.
+	\end{variable}
+	
+	\begin{variable}{\gothamProgressCircHeight, \gothamCounterCircleRadius, \gothamProgressCircBorderWidth} 
+		Lengths controlling the aspect of |progress circle|.
+		|\gothamProgressCircHeight| is controlling the inner height of the circle (related to its diameter).
+		|\gothamCounterCircleRadius| is controlling the size of the counter circle containing the frame number.
+		|\gothamProgressCircBorderWidth| is controlling width of the progress circle.
+	\end{variable}
+
+	\begin{figure}[htp]
+		\centering
+		\fbox{\includegraphics[width=0.7\textwidth]{gotham-layout.pdf}}
+		\caption{The layout used by \themename.}
+	\end{figure}
+
+
+%% ------------------------------------
+\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 for slides in the appendix.
+
+
+\subsection{Sources of inspiration}
+	Many Beamer themes have been used as sources of inspiration to build \themename{}:
+	\begin{itemize}
+		\item \url{https://github.com/matze/mtheme} for dark/light theme and standout page.
+		\item \url{https://github.com/hamaluik/Beamer-Theme-Execushares} and
+			\\ \url{https://github.com/pcafrica/focus-beamertheme} for titlepage and sectionpage.
+		\item \url{https://github.com/LukasPietzschmann/awesome-beamer} for titlepage.
+		\item \url{https://github.com/luistar/unina-beamer/tree/master} and
+			\\ \url{https://github.com/jkjaer/aauLatexTemplates/tree/master/aauBeamer/aausimple} for circlehead progress bar.
+		\item \url{https://github.com/povanberg/flux-beamer} for toc.
+		\item \url{https://github.com/fliptanedo/FlipBeamerTheme} for numbering circled fraction.
+		\item \url{https://gitlab.com/RomainNOEL/latex3_template_pkg} for LateX3 template.
+	\end{itemize}
+
+
+%% ------------------------------------
+\section{Known Issues}
+
+\subsection{Title formats}
+\label{sec:titleformats}
+	Be aware that not every font supports small caps, so the |smallcaps| or |upper| 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 |upper| and |smallcaps| 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 |upper|. 
+			(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 |smallcaps| and |upper| 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{gotham}| 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{gotham}
+		\usecolortheme{seahorse}
+	\end{lstlisting}
+	
+	The correct colors are chosen if the \themename outer, inner, and font themes are loaded seperately:
+	\begin{lstlisting}
+		\useoutertheme{gotham}
+		\useinnertheme{gotham}
+		\usefonttheme{gotham}
+		\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 into Beamer and compile with XeLaTeX, text on slides following the first section slide may be rendered in white instead of the regular color. 
+	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}|.
+
+
+\subsection{Other issues}
+	\begin{itemize}
+		\item |enumitem| is not working with Beamer.
+	\end{itemize}
+
+
+\subsection*{Todo}
+	List of thing that could be improved (any volunteer welcome):
+	\begin{itemize}
+		\item Reduce the number of @ .
+		\item Rename a lot of length with gotham at the beginning of their name.
+		\item Turn internal length into \_dim.
+		\item Improve documentation.
+		\item Add a hexagonal, wavy and add lengths on the blueprint layout backgrounds.
+		\item Remove calc package (that can be replaced by xfp or just fp).
+		\item Remove colors from tests inner and outer.
+		\item Replace the |\setbeamertemplate{yy}[default/xx]| by |\__gotham_inner_set_template:nn{title~page}| or merge them  because the default values in dict/template are interesting but |\__gotham_inner_set_template| are simpler.	
+		\item  add colorset more "blue-ish", "green-ish" ... from colorA etc.
+		\item add Gotham to lists of Awesome Beamer themes.

+	\begin{frame}[fragile]{Commands controlling overlay}
+		Beamer defines a bunch of commands intended to control overlays:
+		\verb$\only<...>{text}$ Throws away \verb$text$ content on slides not in \verb$<...>$
+		\verb$\onslide<...>{text}$ Same, but when hidden \verb$text$ still takes space.
+		\verb$\visible<...>{text}$ Same.
+		\verb$\uncover<...>{text}$ Same, but also handle transparency.
+		\verb$\invisible<...>{text}$ Opposite of \verb$\visible$
+		\verb$\alt<...>{text1}{text2}$ Alternates between \verb$text1$ and \verb$text2$ for\verb$ <...>$.
+		\verb$\temporal<...>{before}{inside}{after}$ Alternate between three texts	depending on slide index before, inside or after the range of \verb$<...>$.
+		For the commands \verb$\only$ and \verb$\alt$ the \verb$<...>$ can also be after the text.
+		Then \verb$\only$ can be used to make commands \verb$<...>$-aware (§9.3) like in:
+		\verb$\newcommand{\myblue}{\only{\color{blue}}}$
+		\verb$\myblue<2> This text is blue only on slide 2.$
+		Finally, \verb$\only$ and \verb$\onslide$ without text argument work as toogles.
+		Much more options, described in §9.4 to 9.6
+	\end{frame}
+
+	% FRAME from https://www.edpif.org/documents/latex/intermediate/beamer/latex-int-beamer_handout.pdf
+	\begin{frame}[fragile]{Action specifications}
+		Inside \verb$<...>$ it is possible to add some action specifications
+		Action are specified after the slide range \& a | and followed by @ and the target slide or range. 
+		For example one can write:
+		\verb$\item<3-|alert@4> Shown from slide 3 on, alerted on slide 4.$ 
+		which set the \verb$\alert$ for item 3 only in slide 4.
+		Actions can be defined for \verb$\item$, \verb$\action$, \verb$\begin{actionenv}\verb$
+		and the block environments and the possible actions are by default,
+		alert, uncover, only, visible, invisible, but other can be
+		defined by the user. See manual § 9.6.3
+		Simple example using uncover with specified transparency:
+		\begin{verbatim}
+		\setbeamercovered{transparent=30}
+		\begin{itemize}[<+-|uncover@+>]
+			\item first
+			\item second
+			\item third
+		\end{itemize}

+\section{Gotham Theme}
+
+	% FRAME
+	\begin{frame}[fragile]{Gotham}
+	
+		The \themename{} theme is a Beamer theme with a minimal-ish visual style largely inspired by the \href{https://github.com/matze/mtheme}{\textsc{Metropolis} Beamer Theme} by Matthias Vogelgesang (and some other Beamer themes).
+
+		Yet, \themename{} is highly extendable and versatile.
+		\bigskip
+		
+		First, enable the theme by classically loading it:
+		
+		\begin{verbatim}
+			\documentclass{beamer}
+			\usetheme{gotham}
+		\end{verbatim}
+		
+		Then, the all customization can be performed at any moment in the presentation using:
+
+		\begin{verbatim}
+			\gothamset{<option>=...}
+		\end{verbatim}
+	\end{frame}
+
+
+\subsection{Fonts}
+
+	% FRAME	
+	\begin{frame}[fragile]{Gotham title formats}
+		Note, that you have to have Mozilla's \emph{Fira Sans} font and XeTeX or LuaTeX installed to enjoy this wonderful typography.
+
+		\begin{columns}[T,onlytextwidth]
+		\column{0.49\textwidth}
+			\themename{} supports 4 different title formats \verb|\gothamset{format frametitle=}|
+			\begin{itemize}
+				\item regular
+				\item \MakeLowercase{Lower}
+				\item \MakeUppercase{Upper}
+				\item \MakeTitlecase{Title Case}
+			\end{itemize}
+		\column{0.49\textwidth}
+			\themename{} supports 3 different title shape \verb|\gothamset{shape frametitle=...}|:
+			\begin{itemize}
+				\item regular
+				\item \textsc{Small caps}
+				\item \textit{italic}
+			\end{itemize}
+		\end{columns}
+		
+		\vspace{2em}
+		They can either be set at once for every title type or individually.
+	\end{frame}
+
+	{
+	\gothamset{shape frametitle=smallcaps, format frametitle=titlecase}
+	% FRAME
+	\begin{frame}{Titles: Small caps and titlecase}
+		This frame uses the title format options: \texttt{shape frametitle=smallcaps, format frametitle=titlecase}.
+
+		\begin{alertblock}{Potential Problems}
+			Be aware that not every font supports small caps. 
+			If for example you typeset your presentation with pdfTeX and the Computer Modern Sans Serif font, every text in small caps will be typeset with the Computer Modern Serif font instead.
+			Please refer to the documentation if you consider using it.
+
+			As a rule of thumb: just use it for plaintext-only titles.
+		\end{alertblock}
+	\end{frame}
+	}
+
+	{
+	\gothamset{format frametitle=upper, shape frametitle=italic}
+	% FRAME
+	\begin{frame}{Titles: Upper and italic}
+		This frame uses the title format options: \texttt{format frametitle=upper, shape frametitle=smallcaps}.
+
+		\begin{alertblock}{Potential problems}
+			As this title format also uses small caps you face the same problems as with the \texttt{smallcaps} title format. 
+			Additionally this format can cause some other problems. 
+			Please refer to the documentation if you consider using it.
+

+		\end{verbatim}
+	\end{frame}
+
+
+\subsection{Inner}
+
+	% FRAME
+	\begin{frame}[fragile]{Title page}
+		\themename{} offers the possibility to adapt the title page layout (printed with \verb|\maketitle| or \verb|\titlepage|).
+		This can be achieved using:
+
+		\begin{verbatim}   \defbeamertemplate{title page}{your name}{your defintion}
+			\gothamset{title page= your name}\end{verbatim}
+		
+		\themename{} also predefined several templates such as: 
+		\verb$gotham normal | gotham splitvert | gotham dividedpic$ \verb$| gotham reversed$
+	\end{frame}
+
+	% FRAME
+	\begin{frame}[fragile]{Table of contents}
+		\themename{} come with the possibility to apply different style for your table of contents (ToC) page.
+		You can define your own ToC style as it follows:
+		\begin{verbatim}
+			\defbeamertemplate{toc page}{your name}{your def}
+			\gothamset{tocframe template= your name}
+		\end{verbatim}
+		Then, referring to this template using the frame option \verb|[toc]| in your presentation: 
+		\begin{verbatim}
+			\begin{frame}[toc]{Table of contents}
+				\tableofcontents%[hideallsubsections]
+			\end{frame }\end{verbatim}
+
+		Or using one of the \themename{} predefined template, such as: \verb$gotham simple | gotham bullet$
+	\end{frame}
+
+	% FRAME
+	\begin{frame}[fragile]{Sections}
+		\themename{} provides a multiple options to tune sections (respectively \verb|part|, \verb|section|, \verb|subsection| and \verb|subsubsection|).
+		Thus, using the setting controls:
+		
+		The section command \verb|\section{Elements}| from Beamer will appear very differently.
+		The section page will appear or disappear thanks to: \verb$\gothamset{sectionframe default=<on|off>}$, while its layout (when appearing) is controlled by: 
+		\begin{verbatim}
+			\defbeamertemplate{part|sub|subsub|section frame}
+				{your name}{your def}
+			\gothamset{sectionframe template= your name}\end{verbatim}
+
+		\themename{} predefined template are: \verb$gotham progressbar | gotham simple |$ \verb$gotham splitvert progressbar |$ \verb$gotham splitvert simple | gotham progressvert$
+	\end{frame}
+
+	% FRAME
+	\begin{frame}[fragile]{Sections contents}
+		After the section page, you can (de)activate a page with table of contents in the section using \verb$\gothamset{sectiontocframe default=<on|off>}$, and its layout is controlled by: 
+		\begin{verbatim}
+			\defbeamertemplate{toc subsection frame}{your name}{your def}
+			\gothamset{sectionframe template= your name}
+		\end{verbatim}
+
+		\themename{} predefined template are: \verb$gotham simple | gotham bullet$
+	\end{frame}
+
+	% FRAME
+	\begin{frame}[fragile, watermark]{Watermark}
+
+		With \themename{} you can locally or globally add watermark to your slides by using:
+		\begin{verbatim}  \defbeamertemplate{background}{watermark/your name}{your def}
+		  \gothamset{watermark template= your name}\end{verbatim}
+		
+		Then, this watermark can be turn on locally using \verb|\begin{frame}[watermark]| or globally with \verb|\gothamset{watermark default= on}| .
+ 	\end{frame}
+
+	% FRAME
+	\begin{standinenv}
+	\begin{frame}[fragile]{Standin}
+
+		\themename{} comes with 2 environments/specials layouts named \verb|standin| and \verb|standout|.
+		These specials layouts can be used to emphasize some content or last slide\textellipsis
+
+		This layout can be turn on using \verb|\begin{frame}[standin]| or using the dedicated environment (\verb|\begin{standinenv}\begin{frame}...\end{frame}\end{standinenv}|).
+
+		Note that the background can also be tuned using:
+		\begin{verbatim}  \defbeamertemplate{background canvas}{standin/name}{your def}
+		  \gothamset{standin template= name}\end{verbatim}
+		
+	\end{frame}
+	\end{standinenv}
+
+	% FRAME
+	\begin{frame}[fragile, standout, watermark]{Standout}
+		Here is an example of standout (working as standin), that can be combined with a watermark.
+
+		Another difference, apart the obvious color change is the font size and series.
+	\end{frame}
+
+
+\subsection{Outer}
+	
+	{%
+		\setbeamertemplate{frame footer}{My custom footer}
+	% FRAME
+	\begin{frame}[fragile]{Frame footer}
+	   \themename{} defines a custom Beamer template to add a text to the footer. 
+		It can be set via
+	   \begin{verbatim}\setbeamertemplate{frame footer}{My custom footer}\end{verbatim}
+
+		Even after redefining (or not) your frame footer template, you can locally remove it with the frame option \verb|\begin{frame}[nofooter]|.
+	\end{frame}
+	}
+
+	\title[your shorttitle]{Gotham}
+	\date[shortdate]{\today}
+	\author[your shortauthor name]{Romain NOËL}
+	% FRAME
+	\begin{frame}[fragile, rotateFooter]{rotateFooter}
+		The default footer from \themename{}, it displays the \verb|shortdate|, \verb|shorttitle| and \verb|shortauthor|.
+		So by filling these fields in your document setup, you will see them appear in your footer:
+		\begin{verbatim}   \title[your shorttitle]{Your title}
+			\date[shortdate]{\today}
+			\author[your shortauthor name]{John DOE} \end{verbatim}
+
+		Since, we always need some extra space on some frames that would like to overlay a bit the footer, \themename{}'s footer offers also possibility to be put on side locally using \verb|\begin{frame}[rotateFooter]|, or globally with 
+		\begin{verbatim} \gothamset{rotateFooter default=on} \end{verbatim}
+		If it has set globally, it can be deactivated locally with the frame option \verb|\begin{frame}[norotateFooter]|.
+	\end{frame}
+
+	\title[]{Gotham}
+	\date[]{\today}
+	\renewcommand{\gothamRightFiligrane}{%
+		\rotatebox{90}{gotham right filigrane pattern}
+	}
+	% FRAME
+	\begin{frame}[edging, fragile]{Edging}
+		\themename{} has two hook commands, \verb|\gothamRightFiligrane| and \verb|\gothamLeftFiligrane|, that can be redefined to customize what to display in the edgings (a.k.a. filigrane, a.k.a. sidebar).
+		As example, one could do:
+		\begin{verbatim}
+			\renewcommand{\gothamRightFiligrane}{%
+				\rotatebox{90}{gotham right filigrane pattern}
+			}\end{verbatim}
+
+		Then, to set if it should be displayed or not, globally \begin{verbatim} \gothamset{edging default=on} \end{verbatim}
+		or locally with the frame option \verb|\begin{frame}[edging]| or \verb|\begin{frame}[noedging]|.
+	\end{frame}
+
+	% FRAME
+	% \begin{nofootlineenv}
+	\begin{frame}[fragile,noedging,nofooter]{Really wide contents}
+		\begin{adjustwidth}{-2em}{-2em}
+			If you want a really wide content in your frame, you can change the size of your margin (requires \verb|\usepackage{changepage}| in your preamble).
+			You can also suppress the edging (\verb|[noedging]|) and footer (\verb|[nofooter]|) or even more radically footline (\verb|[nofootline]|).
+
+			Here is an example combining them: 
+			\begin{verbatim}
+				\begin{frame}[noedging,nofootline]{extended frame}
+					\begin{adjustwidth}{-2em}{-2em}% 2em extra to the left and 2em for right margin.
+						wide content
+					\end{adjustwidth}
+				\end{frame }
+			\end{verbatim}
+		\end{adjustwidth}
+	\end{frame}
+	% \end{nofootlineenv}
+
+	{%
+	\renewcommand{\gothamInstituteLogoSquare}[1][4ex]{%
+      \includegraphics[height=#1]{gotham-logo.pdf}
+   }
+	\logo{extra LOGO}
+	% FRAME
+	\begin{frame}[fragile]{Frametitle}
+		\framesubtitle{with a subtitle}
+		The frametile template brought by \themename{} is relatively classic: it supports \verb|\subframetitle| and frame continuation (with \verb|[allowframebreaks]|) through templates that can be tuned.
+		Nevertheless, it the frametitle template also includes a hook for your institute logo in the top right corner, leaving the command \verb|\logo{}| free for your extra logos.
+		
+		So, one can have both logos using:
+		\begin{verbatim}
+			\renewcommand{\gothamInstituteLogoSquare}[1][4ex]{
+				\includegraphics[height=#1]{gotham-logo.pdf}
+			}
+			\logo{extra LOGO}
+		\end{verbatim}
+	\end{frame}
+	}
+
+	\author[]{Romain NOËL}
+	{%
+		\gothamset{progressbar position=foot, numbering= totalframenumber}
+	% FRAME
+	\begin{frame}[fragile]{Numbering and progressbar}
+
+		\themename{} theme can numbering your frames in the bottom right corner using different styles. 
+		You can also decide to use a progression bar to indicate how much of your presentation remains.
+
+		The setup of numbering and progression bar can be performed through:
+		\begin{verbatim}
+			\gothamset{numbering= totalframenumber, progressbar position=foot}
+		\end{verbatim}
+
+		Numbering available options are: \verb$none | framenumber | totalframenumber | appendixframenumber | pagenumber | totalpagenumber | circle$
+
+		Progressbar position available options are: \verb$none | head | frametitle | foot | circlehead$

+%   \begin{macro}{\begin{frame}[c]}
+%     Add a frame option |c| for improved vertically centered text in the frame.
+%     By default, Beamer frames offer the |c| option to \textit{almost} vertically center the text, but the placement is a little too high.
+%     To fix this, we redefine the |c| option to equalize |\beamer@frametopskip| and |\beamer@framebottomskip|. 
+%     This solution was suggested by Enrico Gregorio in an answer to \href{http://tex.stackexchange.com/questions/247826/}{this Stack Exchange question}.

+	% Unfortunately, |colsep| also adds this separation if the background color is inherited, even if the inherited color is actually empty.
+	% (The technical reason for this boils down to the fact that the |\ifx| directive does not expand macros.)
+	%
+	% To achieve the correct spacing for |alertblock|s and |exampleblock|s as well as for normal blocks, we have to begin the |beamercolorbox| differently based on whether |block title| has an empty background.
