title: Heroku - custom SUBdomain
body: <p>My client would like to point his Heroku app to a subdomain of his current website (lets say <code>example.com</code> and <code>subdm.example.com</code>).</p>
  
  <p>Heroku provides nice example, how to set up pointing from Heroku app to custom domains - <a href="https://devcenter.heroku.com/articles/custom-domains" rel="nofollow">https://devcenter.heroku.com/articles/custom-domains</a></p>
  
  <p>But how to do pointing from Heroku app to custom SUBDOMAIN?</p>
  
  <p>Should I set up just <code>heroku domains:add subd.example.com</code>?</p>
  
  <p>I am rather asking for an advice, because I don't wanna screw up client's website and setup...</p>
  
  <p>Thanks</p>
