ow, focusing only on the <code>head</code> of our HTML document, let&#39;s add template variables for <code>title</code> and <code>author</code> so that we can later replace them with real data:</p>
            <pre><code class="language-html">&lt;!DOCTYPE html&gt;
&lt;html lang=&quot;en&quot;&gt;
  &lt;head&gt;
    &lt;title&gt;{{title}}&lt;/title&gt;
    &lt;meta name=&quot;author&quot; content=&quot;{{author}}&quot;&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;/body&gt;
&lt;/html&gt;</code></pre>
