-First a detailed overview of the available integration algorithms is given, including their advantages and disadvantages.
-After that the interaction potentials and their accuracy for describing certain systems of elements are discussed.
+Three ingredients are required for an MD simulation:
+\begin{enumerate}
+\item A model for the interaction between system constituents is needed.
+ Interaction potentials and their accuracy for describing certain systems of elements will be outlined in chapter \ref{subsection:interact_pot}.
+\item An integrator is needed, which propagtes the particle positions and velocities from time $t$ to $t+\delta t$, realised by a finite difference scheme which moves trajectories discretely in time.
+ In chapter \ref{subsection:integrate_algo} a detailed overview of the available integration algorithms is given, including their advantages and disadvantages.
+\item A statistical ensemble has to be chosen, which allows certain thermodynamic quantities to be controlled or to stay constant.
+ This is discussed in chapter \ref{subsection:statistical_ensembles}
+\end{enumerate}
