+This tutorial is designed to give the user a **quick glimpse** of some key aspects of the simulation assembled toolkit and is in no way near a full treatment.
+Rather, the aim of this tutorial is to **provide starting point** to quickly begin simulation work with the modern software tools.
+The key toolkit components were thoughtfully selected to (i) leverage externally supported and maintained projects, (ii) decouple framework as much as possible, (iii) allow for modern tools to be developed  with the vision of using these tools for next decade.
+The key software components are:
+ - DD4hep (with Geant4 and ROOT)
+ - GAUDI
+ - ACTS
+ - podio
+
+
 ## DD4hep 
 
 DD4hep introduces the concept of a `DetElement` which is related to the volumes (logical volumes) and placed volumes but not in a strict way.
