+\subsubsection{Code}
+If you get compilation errors, be sure to enable \texttt{-shell-escape} for your compiler.

+\paragraph{Code in separate files}
+It is also possible to load code from a source file using the provided commands:
+\begin{itemize}
+    \item \verb|\inputcode|\{\textit{language}\}\{\textit{file}\}, where \textit{language} is the programming language
+          and \textit{file} is the file name of the file to be loaded, relative to the main tex file.
+    \item \verb|\inputcodewithfilename|\{\textit{language}\}\{\textit{hidden-path}\}\{\textit{shown-path}\}, where \textit{language} is the programming language,
+          \textit{hidden-path} is the part of the path you want to hide of the file to be loaded, relative to the main tex file
+          and \textit{shown-path} is the displayed part.
