+    # == Queue Classic adapter for Active Job
+    #
+    # queue_classic provides a simple interface to a PostgreSQL-backed message
+    # queue. queue_classic specializes in concurrent locking and minimizing
+    # database load while providing a simple, intuitive developer experience.
+    # queue_classic assumes that you are already using PostgreSQL in your
+    # production environment and that adding another dependency (e.g. redis,
+    # beanstalkd, 0mq) is undesirable.
+    #
+    # Read more about Queue Classic {here}[https://github.com/ryandotsmith/queue_classic].
+    #
+    # To use Queue Classic set the queue_adapter config to +:queue_classic+.
