+By default, the recipe will install Sidekiq on utility instances with the name `sidekiq`. If the utility name is `nil` or there is no utility instance matching the name given, Sidekiq will be installed on all application/solo instances.
 
 If you wish to have more than one sidekiq utility instance, name the sidekiq utility instances as "sidekiq" and also set the `utility_name` to `sidekiq`.
 
+NOTE: If you change the `utility_name` setting, say, from `sidekiq_old` to `sidekiq_new`, the sidekiq monitrc file will not be cleaned up for you, and sidekiq will continue running on the `sidekiq_old` instances. You will have to do a manual cleanup on the `sidekiq_old` instances: stop sidekiq, remove the sidekiq .monitrc file in `/etc/monit.d/`, then run `sudo monit reload`.
+
+The manual cleanup is the recommended approach for production environments. For development environments, we have provided the `sidekiq::cleanup` recipe. Just uncomment this line in `recipes/default.rb`:
+
+```
+# include_recipe "sidekiq::cleanup"
+```
+
+We do not recommend enabling it on production environments because when this is enabled, the sidekiq workers will be restarted every chef run.

 ## Multi Instance Deploys
 
 By default engineyard will install Redis to your DB instance and if you wish to keep it there rather than the preferred method of creating a utility instance you will need to tell Sidekiq where to find Redis. You can do this by adding a Sidekiq intializer in `config/initializers/sidekiq.rb` with the following information:
