+    # == Qu adapter for Active Job
+    #
+    # Qu is a Ruby library for queuing and processing background jobs. It is
+    # heavily inspired by delayed_job and Resque. Qu was created to overcome
+    # some shortcomings in the existing queuing libraries that we experienced.
+    # The advantages of Qu are: Multiple backends (redis, mongo), jobs are
+    # requeued when worker is killed, resque-like API.
+    #
+    # Read more about Que {here}[https://github.com/bkeepers/qu].
+    #
+    # To use Qu set the queue_adapter config to +:qu+.
+    #
+    #   Rails.application.config.active_job.queue_adapter = :qu
