+quarkus.datasource.db-kind=postgresql
+# add ':otel' to your database URL
+quarkus.datasource.jdbc.url=jdbc:otel:postgresql://localhost:5432/mydatabase
+# use the 'OpenTelemetryDriver' instead of the one for your database

 == Additional configuration
 Some use cases will require custom configuration of OpenTelemetry.
 These sections will outline what is necessary to properly configure it.
