body: <p>How do you add a Worker dyno to a Heroku app?</p>
  
  <p>Their help system includes some information: <a href="https://devcenter.heroku.com/articles/background-jobs-queueing" rel="noreferrer">https://devcenter.heroku.com/articles/background-jobs-queueing</a></p>
  
  <p>including the instruction to use the command line to scale your app:</p>
  
  <pre><code>$ heroku ps:scale web=1 worker=5
  </code></pre>
  
  <p>This returns the response that workers are not defined.</p>
  
  <p>The UI also has a page for adjusting resources:

  <p>But it does not include the option to add workers.</p>
