+## Approach
+
+A special docker container is build to perform the integration tests. This
+container will be build by the makefiles but should only be started by the
+dedicated integration test script. This script will ensure that other containers
+are running and are in the required state.
+
+* Launch pypcc-sim and sdptr-sim simulators.
+* Reconfigure dsconfig to use these simulators.
+* Create and start the integration-test container.
+
+## Limitations
+
+Our makefile will always launch the new container upon creation, resulting in
+the integration tests actually being run twice.
