title: Symfony 4, disable twig cache
body: <p>From symfony 4, how doI disable the twig cache ? </p>
  
  <p>When I edit an .html.twig file, I must clear the cache via the command './bin/console clear:cache' for me to see the updated result in my browser. I would like it to not execute each time the shell command. </p>
  
  <p>In the config/packages/twig.yaml configuration file, I added : </p>
  
  <pre><code>auto_reload: '%kernel.debug%'
  </code></pre>
  
  <p>But nothing changes, I must still execute the cache:clear command each time I modify my templates files.. </p>
