+    # == Que adapter for Active Job
+    #
+    # Que is a high-performance alternative to DelayedJob or QueueClassic that
+    # improves the reliability of your application by protecting your jobs with
+    # the same ACID guarantees as the rest of your data. Que is a queue for
+    # Ruby and PostgreSQL that manages jobs using advisory locks.
+    #
+    # Read more about Que {here}[https://github.com/chanks/que].
+    #
+    # To use Que set the queue_adapter config to +:que+.
+    #
