+#Introduction
+The purpose of the "simulator-group" is to run all containers in one go with specified behavior.
+Mainly this is needed for CSIT tests but can be used also for local testing.
+
+
+###Preparation 
+Build the mr-sim image.
+
+cd ../mr-sim
+
+Run the docker build command to build the image for the MR simulator: 'docker build -t mrsim:latest .
+
+cd ../dr-sim
+
+Run the docker build command to build the image for the DR simulators: `docker build -t drsim_common:latest . 
+
+
+cd ../simulator-group
+
+Copy the 'configuration' and 'tls' catalogues from the ftps-sftp-server dir.
+
+Check the README.md in ftps-sftp-server dir in case the cert need to be updated.
+
+cp -r ./ftps-sftp-server/configuration .
+
+cp -r ../ftps-sftp-server/tls .
+
+
+###Execution
+
+Edit the `docker-compose-setup.sh` to setup the env variables to the desired test behavior for each simulators.
+See each simulator to find a description of the available settings.
+
+Run the script `docker-compose-setup.sh`to create a docker-compose with the desired settings. All simulators
+will be started with the generated docker-compose.yml file
+
+Kill all the containers with `simulators-kill.se`
+
+`simulators_start.sh` is for CSIT test and requires the env variables for test setting to be present in the shell.
+`setup-ftp-files.for-image.sh` is for CSIT and executed when the ftp servers are started from the docker-compose-setup.sh`.
