 We are finally ready to marvel at the aesthetic quality of the listings \pkg{minted} produces.
 You can define listings using a dedicated environment:

+% Render listing directly, if minted is available.
+% Otherwise, include pre-rendered images.

 \noindent There is also a shorthand and an inline variant of the command (cf.\ \cref{lst:minted-variants}).
 To avoid redundancy, it may be practical to import source code directly from the source file.
 To accomplish this, we only have to pass the programming language and the file path to the \code{latex}{\textbackslash inputminted} command (cf.\ \cref{lst:minted-external}).
 
-\example{lst:minted-external}{source-code-listings/minted-import}{Including from a separate file}

 \subsection{Configuring minted}
 Optional parameters allow us to add line numbers, line breaks, and colors.
 Moreover, there are numerous themes available (\cref{lst:minted-external-styled}).
 The introduction on Overleaf and the package documentation\footnote{Available at \url{https://www.overleaf.com/learn/latex/Code_Highlighting_with_minted} and \url{https://ctan.kako-dev.de/macros/latex/contrib/minted/minted.pdf}, respectively.} give an extensive overview.
