 A number of things can be learned:
-\begin{itemize}
-  \item \emph{run-time} parameters can be changed without re-compiling
-  \item \emph{default parameters} are set by default
-  \item \emph{unused} parameters are not used by the simulation (maybe typo or wrong group in input file)
-\end{itemize}

+## Parameter Values
 To get the value of an input parameter please use:
-\begin{lstlisting}[name=propsyscars,style=DumuxCode]
+
+```c++
 static const TYPE paramname = getParam<TYPE>("GROUPNAME.PARAMNAME");
-\end{lstlisting}
+```
 
 If you also want to set a default value for a parameter, just add it like this:
 
-\begin{lstlisting}[name=propsyscars,style=DumuxCode]
+```c++
 static const TYPE paramname = getParam<TYPE>("GROUPNAME.PARAMNAME", default);
-\end{lstlisting}
+```
 
-As this function call is relatively expensive, the respective variables should always be \texttt{static} (e.g., if used in a loop). When dealing with multiple group names, e.g., in the context of coupled models, the following methods might be more convenient:
