+  <description>
+    <p>
+      Zola comes as a single executable with Sass compilation, syntax highlighting, table of contents and many other features 
+      that traditionally require setting up a dev environment adding some JavaScript libraries to your site.
+    </p>
+    <p>
+      The average site will be generated in less than a second, including Sass compilation and syntax highlighting.
+    </p>
+    <p>
+      Zola renders your whole site as static files, making it trivial to handle any kind of traffic you will throw at it at no 
+      cost without having to worry about managing a server or a database.
+    </p>
+    <p>
+      From the CLI to the template engine, everything is designed to be intuitive. Don't take my word for it though, look at the
+      documentation and see for yourself.
+    </p>
+    <p>
+      Zola gets out of your way so you can focus on your content, be it a blog, a knowledge base, a landing page or a combination 
+      of them.
+    </p>
+    <p>
+      Zola comes with shortcodes and internal links to make it easier to write your content.
