1. Clone the project and open it with IntelliJ
2. Navigate to the project folder and run the Active MQ Artemis by executing the command docker-compose -f broker-compose.ym up mq
3. Run the class WebSocketApplication
4. Access the Client page at http://localhost:8181
5. On IntelliJ duplicate the Runner for WebSocketApplication and add the VM parameter -Dserver.port=8282 to open a new instance in other port.
