+	Images can just be imported and used in a float enviroment with a caption and a lable to reference it.

 		\caption{just a random image}
 	\end{figure}
 
+	Plots can be created direktly with latex. It is recomendet to do this in subfiles and just import the finished PDF pages. This speed us
+	compiletimes by a lot. You should not change the size of precompiled images to keep fontsizes consistent.

+\section{using Units}
+	For this the \lstinline{siunitx} package is used. It provides Macros for all units.
+	\begin{equation}
+		200\,\ohm
+	\end{equation}
+	The space betwen a number and it's unit shoud be a protected half-space, which can be created in latex using \lstinline{\,} In the classfile
+	siunits is set up to use a seperate macro for each subunit, even for size-modifiers:
+	\begin{equation}
+		200\,\milli\metre \cdot 2\,\mega\volt
+	\end{equation}
+	Siunits also allows for reformating of numbers as well as units. Use the \lstinline{\SI} and \lstinline{\si} macros for that:
+	\begin{equation}
+		e = \SI{1.602176634E-19}{\coulomb} % formats number + units, autospacing, transform to gernam comma
