 Backburner is extremely simple to setup. Just configure basic settings for backburner:
 
 ```ruby
 Backburner.configure do |config|
-  config.beanstalk_url       = ["beanstalk://127.0.0.1", "..."]
+  config.beanstalk_url       = "beanstalk://127.0.0.1"

 ## Breaking Changes
 
 Before **v0.4.0**: Jobs were placed into default queues based on the name of the class creating the queue. i.e NewsletterJob would
 be put into a 'newsletter-job' queue. As of 0.4.0, all jobs are placed into a primary queue named "my.app.namespace.backburner-jobs"
