 \section{\acrlong{TOP}}
 \gls{TOP} is a recent new programming paradigm implemented as
-\gls{iTasks}~\cite{achten_introduction_2015} in
-the pure lazy functional language \gls{Clean}
+\gls{iTasks}\cite{achten_introduction_2015} in the pure lazy functional
+language \gls{Clean}\cite{brus_cleanlanguage_1987}. \gls{iTasks} is a
+\gls{EDSL} to model workflow tasks in the broadest sense. A \CI{Task} is just
+a function that, given some state, returns the observable value of the
+\CI{TaskValue}. A simple example is shown in Listing~\ref{lst:taskex}
+accompanied with Figure~\ref{fig:taskex1},~\ref{fig:taskex2} and~%
+\ref{fig:taskex3}.
