 ## Restarting your workers
 
 This recipe does NOT restart your workers. The reason for this is that shipping your application and
-rebuilding your instances (i.e. running chef) are not always done at the same time. It is best to 
-restart your Delayed Job workers when you ship (deploy) your application code. To do this, add a
-deploy hook to perform the following:
-
-    sudo "monit -g dj_<app_name> restart all"
-
-Make sure to replace <app_name> with the name of your application. You likely want to use the
-after_restart hook for this. See our [Deploy Hook](https://engineyard.zendesk.com/entries/21016568-use-deploy-hooks) documentation

+
+If you're running DelayedJob on a solo instance or on your app_master, add a deploy hook similar to:
+
+```
+on app_master do
+  sudo "monit -g dj_#{config.app} restart all"
+end
+```
+
+On the other hand, if you'r running DelayedJob on a dedicated utility instance, the deploy hook should be like:
+
+```
+on_utilities :delayed_job do
+  sudo "monit -g dj_#{config.app} restart all"
+end
+```
+
+Make sure to replace <app_name> with the name of your application. You likely want to use the after_restart hook for this.
