+The only thing you need to do is add a dependency in build.gradle to the MySQL/PostgreSQL/whatever JDBC driver.
+Search in Jcenter for the database driver suitable for the database installed on your production system.
+For example, under the dependencies section you can add something like this for mysql: `runtime 'mysql:mysql-connector-java:5.1.36'`
+Of course you need to make sure the connector is compatible with _your_ version of the database installed!
