+         (en "RabbitMQ is an Erlang application.  It uses Erlang Port Mapper
+Daemon (epmd).  To prevent RabbitMQ from starting its own epmd instance,
+the epmd service is added to enable control and configuration of the daemon.
+
+By default, Guix runs epmd service using local network interfaces.
+See the following articles for the rationale.

+@end itemize
+
+To use RabbitMQ service, add epmd to the list of services, for example:
+@example
+(services
+  (service epmd-service-type)
+  (service rabbitmq-service-type))
+@end example")))
