+All workers should include `ApplicationWorker` instead of `Sidekiq::Worker`,

 ## Dedicated Queues
 
-Most workers should use their own queue. To ease this process a worker can
-include the `DedicatedSidekiqQueue` concern as follows:
-
-```ruby
-class ProcessSomethingWorker
-  include Sidekiq::Worker
-  include DedicatedSidekiqQueue
-end

-This will set the queue name based on the class' name, minus the `Worker`
-suffix. In the above example this would lead to the queue being
-`process_something`.
+Most workers should use their own queue, which is automatically set based on the
+worker class name. For a worker named `ProcessSomethingWorker`, the queue name
+would be `process_something`. If you're not sure what a worker's queue name is,
+you can find it using `SomeWorker.queue`.
 
 In some cases multiple workers do use the same queue. For example, the various
 workers for updating CI pipelines all use the `pipeline` queue. Adding workers
