 # ETCS
 European Train Control System implementation
 ETCS is a standard European safety system for railway interoperability between countries. This code tries to implement some of its features. Most DMI graphical functions work, as well as speed and distance monitoring.
+
+The DMI is the graphical interface. The EVC is the computer the DMI connects to. For connecting to ETCS within games like Simrail you should only need the DMI. 
+
