+*Simkit* is a powerful tool for modeling and simulation that can be networked 
+with other applications by integrating use of the 
+Distributed Interactive Simulation (DIS) protocol.
+This directory includes simple Simkit programs which are getting modified to
+utilize (opendis7-java)[https://savage.nps.edu/opendis7-java] libraries for PDU output.
+
+*Viskit* is a visual editor for authoring Simkit event graphs and simulation assemblies.
+Models are authored visually and saved as XML, which in turn generates Simkit Java code.
+This tool is newly restored and we are now building examples that integrate
+DIS capabilities with Simkit.
 
 ## Design Goals
 
 * Integrate code to share state changes from Simkit entities as DIS PDU messages.
 * Establish reference examples with corresponding output logs for test confirmation.
-* Build interoperability examples for distributed simulation using Simkit, DIS and X3D.
+* Build interoperability examples for distributed simulation using Simkit, Viskit, DIS and X3D.
