body: <p>I have next project roles:</p>
  
  <pre><code>hosts
  site.yml
  /roles
    /proxy
      /tasks
      ...
    /web
      /tasks
      ...
    /worker
      /tasks
      ...
    /db
      /tasks
      ...
  </code></pre>
  
  <p>I need to install chruby on <code>web</code> and <code>worker</code>. So installed <a href="https://github.com/ferrarimarco/ansible-role-chruby" rel="nofollow">https://github.com/ferrarimarco/ansible-role-chruby</a> from Galaxy, but I don't know how to add tasks from chruby to <code>web</code> and <code>worker</code> roles.</p>
  
  <p>Please advice.</p>
