-\item Wij zijn wij
-\item \clash{} voor rapid prototyping
-\item Subset haskell vertaalbaar
-\item Mealy machine beschrijving
+\item We are a Computer Architectures group, this has been a Masters' project, no prior experience with Haskell.
+\item \clash{} is written in Haskell, of course
+\item \clash{} is currently meant for rapid prototyping, not verification of hardware designs
+\item Functional languages are close to Hardware
+\item We can only translate a subset of Haskell
+\item All functions are structural descriptions with a Mealy Machines perspective

-Voor wie het niet meer weet, dit is een mealy machine
+\note[itemize]{
+\item A Mealy machine bases its output on the current state and the input
+\item State is part of the function signature
+\item Both the current state, and the updated State
+\item The run function simulates a mealy machine for the provided number of inputs
