+= Module D: Extend experiment script =
+
+In this module, we will take a look at the modifications that have to be made in the experiment script to evaluate correct 
+functionality of both learning switches in the extended topology. This example shows that it is relatively easy to adapt an 
+existing OEDL script to an extended or slightly modified topology.
