+        <h2 id="valo">Valo theme</h2>
+        
+        <p>Valo is a brand new built-in theme for Vaadin. It leverages 
+        the <a href="http://www.sass-lang.com">Sass CSS preprocessor</a> heavily, 
+        providing a variety of ways to customize the look and feel of your theme. 
+        Read the introductory blog post describing the features for the
+        <a href="https://vaadin.com/blog/-/blogs/7-series">Vaadin 7.x series</a>.</p>
+        
+        <h4>Using Valo</h4>
+        
+        <p>The Java-based Sass compiler bundled with this Vaadin release 
+        does not support all the features that Valo requires at the moment. 
+        The compiler in the release version of Vaadin 7.3 will support Valo, 
+        but for this alpha release, you need to use the original Ruby-based 
+        compiler (or any other Sass 3.2 compatible Sass compiler). See 
+        instructions below.</p>
+        
+        <ul>
+          <li>Install the command-line version of the Sass compiler by following 
+          the instructions in <a href="http://sass-lang.com/install">http://sass-lang.com/install</a></li>
+          <li>Unpack the <code>VAADIN/themes/valo</code> folder from 
+          <code>vaadin-themes-7.3.0.alpha1.jar</code> and place it under your 
+          project's <code>VAADIN/themes</code> folder</li>
+          <li>In your project's custom theme, import Valo and do any modifications 
+          you wish using the Sass API in Valo (i.e., variables, mixins, and functions), 
+          and then include the main valo mixin<br>
+            <br>Example (in <code>my-theme-name.scss</code>):<br>
+            <pre>// Any variables you wish to override should be done before importing Valo
+
+// Modify the base color of the theme
+$v-app-background-color: hsl(200, 50%, 50%);
+
+@import "../valo/valo";
+
+.my-theme-name {
+  @include valo;
+}
+</pre>
+          </li>
+          <li>From the command-line, navigate to your project's 
+          <code>VAADIN/themes/my-theme-name</code> folder and use the following command 
+          to compile the theme:<br><br>
+          <code>$ sass styles.scss styles.css</code></li>
+        </ul>
 
         <h3 id="limitations">Limitations</h3>
         <ul>
-            <li>It is currently not possible to specify <tt>font-size</tt>
+            <li><p>It is currently not possible to specify <tt>font-size</tt>
                 as <tt>em</tt> or <tt>%</tt>, or layout component sizes
                 with <tt>em</tt> (<a
-                href="http://dev.vaadin.com/ticket/10634">#10634</a>)
+                href="http://dev.vaadin.com/ticket/10634">#10634</a>).</p><p>This 
+                does not apply to Valo, but using em sizes to size layouts is discouraged, 
+                because it results in fractional component sizes in many cases, which 
+                might cause unwanted 1px gaps between components.</p>
             </li>
             <li>Push is currently not supported in portals (See <a
                 href="http://dev.vaadin.com/ticket/11493">#11493</a>)
