+
+**TODO: rename *producer* to *publisher*.**
+
+A `Reactive Streams`_ ``Producer`` can be created from a processor's message stream via the ``PersistentFlow``
+extension of the Akka Streams Scala DSL:
+
+.. includecode:: code/docs/persistence/PersistenceDocSpec.scala#producer-creation
+
+The created ``flow`` object is of type ``Flow[Persistent]`` and can be composed with other flows using ``Flow``
+combinators (= methods defined on ``Flow``). Calling the ``toProducer`` method on ``flow`` creates a producer
+of type ``Producer[Persistent]``.
+
+A persistent message producer only reads from a processor's journal when explicitly requested by downstream
+consumers. In order to avoid frequent, fine grained read access to a processor's journal, the producer tries
+to buffer persistent messages in memory from which it serves downstream requests. The maximum buffer size per
+producer is configurable with a ``PersistentPublisherSettings`` configuration object.
+
+.. includecode:: code/docs/persistence/PersistenceDocSpec.scala#producer-buffer-size
+
+Other ``ProducerSettings`` parameters are:
+
+* ``fromSequenceNr``: specifies from which sequence number the persistent message stream shall start (defaults
+  to ``1L``). Please note that specifying ``fromSequenceNr`` is much more efficient than using the ``drop(Int)``
+  combinator, especially for larger sequence numbers.
+
+* ``idle``: an optional parameter that specifies how long a producer shall wait after a journal read attempt didn't return
+  any new persistent messages. If not defined, the producer uses the ``akka.persistence.view.auto-update-interval``
+  configuration parameter, otherwise, it uses the defined ``idle`` parameter.
+
+Here are two examples how persistent message producers can be connected to downstream consumers using the Akka
+Streams Scala DSL and its ``PersistentFlow`` extension.
