-\subsection{Extras}
-\subsubsection{BibTeX}
-\textit{Included in \texttt{recommended} and up}
-
+\section{BibTeX}
 Use \verb|\setupBiber|\{\textit{/path/to/your/bib/sources.bib file}\} in the preamble to prepare, then use \verb|\printbib| to print your bibliography.
 
 To add more sources, simply use bibter's built-in macro \verb|\addbibresource|\textit{\{filepath\}}, which will load your \texttt{.bib} file.
 You need to use that inside the preamble as well.
 
 
-\subsubsection{Glossary}
-\textit{Included in \texttt{recommended} and up}
-
+\section{Glossary}
 Use \verb|\setupGlossary| in the preamble to prepare, then use the normal glossary commands to add entries to the glossary. When you want to print it, use \verb|\printGlossary|.
-
-\subsubsection{Minted}
-\textit{Included in \texttt{full}}
-
-Be sure to enable \texttt{-shell-escape} for your compiler
-\textit{(Note: Some newer versions of LaTeX do no longer require this and it is better to keep it turned off for security reasons, if it works without)}!
-
-When \texttt{minted} is available via these helpers, you will also have access to the \texttt{code} environment:
-
-\begin{minted}{latex}
-\begin{code}{language}
-    //Code goes here
-\end{code}
-\end{minted}
-
-This is nothing different than a wrapper for a minted environment with a box drawn around it.
-
-Example (in python):
-
-\begin{code}{python}
-    def hello_world():
-    print("hello world!")
-\end{code}
-
-If you want to print code inline, use \verb|\inlinecode|\textit{\{string\}}, which renders to \inlinecode{code}.
-
-\textit{Caveat: This is not using the \texttt{verbatim} environment due to various limitations of that environment and instead is simply using} \verb|\texttt{}|, so you cannot use this to print \LaTeX-commands
