title: How to modify charts in Helm Stable repo
body: <p><strong>What have I done:</strong><br>
  Added Stable repo into my helm and installed a chart(eg.: Redis, RabbitMQ/someapp).</p>
  
  <pre><code>helm repo add stable https://kubernetes-charts.storage.googleapis.com/
  helm install redis/rabbitMQ/someapp
  </code></pre>
  
  <p><strong>What do I need:</strong><br>
  Now I need to change the configurations of my chart(Redis/RabbitMQ/someapp).<br></p>
  
  <ol>
  <li>How can I edit the chart to have a modified config for my app(Redis/Rabbitmq/someapp)?</li>
  <li>Is it possible to edit the chart's config installed with Helm stable repo? or should I have to have my own repo to edit it?</li>
  </ol>
