 # SUMMA-Actors: Structure for Unifying Multiple Modeling Alternatives with Actors
 
 SUMMA-Actors is a modified version of the already existing SUMMA software that can be 
-found [here](https://github.com/CH-Earth/summa#readme). SUMMA-Actors is a modification 
-of SUMMA that uses the Actor Model to increase scalability and fault-tolerance. The actor which is known as the basic unit of concurrent computation is at the heart of this 
-software. SUMMA-Actors is built using the [C++ Actor Framework](https://github.com/actor-framework/actor-framework).
