-\section{mTask}
-\subsection{Semantics}
-\todo{Uitleggen wat het systeem precies doet}
+Some functionality of the original \gls{mTask}-\gls{EDSL} will not be used in
+this extension \gls{EDSL}. Conversely, some functionality needed was not
+available in the existing \gls{EDSL}. Due to the nature of class based shallow
+embedding this obstacle is very easy to solve. A type housing the \gls{EDSL}
+does not have to implement all the available classes. Moreover, classes can be
+added at will without interfering with the existing views.
+
+\section{Bytecode compilation view}
+The \glspl{mTask} are sent to the device in bytecode and are saved in the
+memory of the device. To compile the \gls{EDSL} code to bytecode a \gls{RWST}
+is used. The \gls{RWST} is a state transformer stacked on a \emph{Reader} monad
+and a \emph{Writer} monad. In this case the transformer part is not used.
+However, this can be done to add for example better runtime error handling.
