title: How to Render multiple templates
body: <p>One base template is created.
  With that rendered first.html one more template.</p>
  
  <pre><code>eg. :
      var tmpl = template.Must(template.ParseFiles(
      "templates/base.html",
      "templates/first.html",
      ))
  </code></pre>
  
  <p>But I also want to add more .html files to render.
  Any reference?</p>
