title: How to use markdown in middleman yaml locals
body: <p>I'm using Middleman localization to push a bunch of documentation from yaml to ruby file. The problem is, I don't know how to use markdown in yaml file and yield the markdown yaml to ruby file. </p>
  
  <p>yaml data file:</p>
  
  <pre><code>features:
      title: "14 Chapters"
      text: "The book's main chapters take you through building a **social news site**."
      image: "files.svg"
      title1: "11 Sidebars"
      text1: "In between each chapter, sidebars explain a specific aspect of Meteor."
      image1: "files.svg"
  </code></pre>
  
  <p>locals.html.erb:</p>
  
  <pre><code>&lt;div class="banner"&gt;
      &lt;h2 class="s-heading"&gt; 
            &lt;%= I18n.t("features.title") %&gt; 
      &lt;/h2&gt;
      &lt;div class="banner-desc"&gt;
         &lt;p&gt;
           &lt;span&gt; &lt;%= I18n.t("features.text") %&gt; &lt;/span&gt;
         &lt;/p&gt;
      &lt;/div&gt;          
  &lt;/div&gt;
  </code></pre>
