 >Note: The first time running the docker-compose setup, the MySQL server will take a little time to run the initial setup scripts. Due to this, the Servatrice instance may fail the first few attempts to connect to the database. Servatrice is set to `restart: always` in the docker-compose.yml, which will allow it to continue attempting to start up. Once the MySQL scripts have completed, Servatrice should then connect automatically on the next attempt.
