\section*{Installation}
All necessary packages should be installed automagically.\\
The package \texttt{minted} requires Python, which can be installed from \href{https://www.python.org/downloads/}{the official download page}. Make sure to enable to have the \texttt{path} variable set during installation. You then need to install Pygments using the command line:
\mint{bash}|pip3 install Pygments|
Lastly you need to add the \texttt{--shell-escape} flag to the \LaTeX command of your build environment.
