+## External models
+
+To use an external vehicle model, one has to clone the corresponding repository. For the _Autopilot emam_ vehicle model, located in [Autopilot emam repository](https://github.com/MontiSim/EMAM-showcase), the following commands have to be executed:
+
+                    cd MontiSim
+                    git clone https://github.com/MontiSim/EMAM-showcase.git
+                    cd ./EMAM-showcase
+                    mvn clean install
+                    
+                    cd EMAM-showcase/scripts
+                    main.bat
+                    
+The last command `main.bat` will compile the model and run it in a server container to test it.
+
+__NOTE:__ Autopilot EMAM model works only in _Windows 64 bit_ environment.
+
+The scripts in `script` directory are already adjusted to use _Autopilot_ model. If a new model has to be integrated to the RMI Model server, an implementation of _VehicleModel_ has to be created and adjusted with the _ModelManager_. Additionally, all dependencies of the new model have to be declared in the _library_ or _class-path_ of the RMI Model server.
