title: How to deploy Mercure Binary on heroku?
body: <p>I am trying to deploy my Mercure server on a Heroku app
  I downloaded a Linux version of Mercure and extract it and I added this <code>procfile</code> to it:</p>
  <pre><code>web: ADDR=$PORT ./mercure
  </code></pre>
  <p>and I pushed everything using Heroku git</p>
  <pre><code>git push heroku master
  </code></pre>
  <p>but it doesn't work and Mercure fails in the building.
  I can't find any tutorial or anything inside the documentation.</p>
  <p>How can I deploy my Mercure binary on Heroku?</p>
