+ # == 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.
+ # The advantages of Qu are: Multiple backends (redis, mongo), jobs are
+ # requeued when worker is killed, resque-like API.
+ #
+ # Read more about Qu {here}[https://github.com/bkeepers/qu].
+ #
+ # To use Qu set the queue_adapter config to +:qu+.
+ #
+ # Rails.application.config.active_job.queue_adapter = :qu
