+\subsection{Extras}
+\subsubsection{BibTeX}
+\textit{Included in \texttt{recommended} and up}
+
+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}
+
+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!
+
+When \texttt{minted} is available via these helpers, you will also have access to the \texttt{codesnippet} macro:
+
+\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 redners 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
