     <p class="lead">Bootstrap includes a responsive, mobile-first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes <a href="#grid-example-basic">predefined classes</a> for easy layout options, as well as powerful <a href="#grid-less">mixins for generating more semantic layouts</a>.</p>
 
+    <h3 id="grid-media-queries">Media queries</h3>
+    <p>We use the following media queries to create our the key breakpoints in our grid system.</p>
+{% highlight css %}
+/* Extra small devices (phones, up to 480px) */
+/* No media query since this is the default in Bootstrap */
+
+/* Small devices (tablets, 768px and up) */
+@media (min-width: @screen-tablet) { ... }
+
+/* Medium devices (tablets, 992px and up) */
+@media (min-width: @screen-desktop) { ... }
+
+/* Large devices (large desktops, 1200px and up) */
+@media (min-width: @screen-large-desktop) { ... }
+{% endhighlight %}
+    <p>We ocassionally expand on these media queries to include a <code>max-width</code> to limit CSS to a narrower set of devices.</p>
+{% highlight css %}
+@media (max-width: @screen-phone-max) { ... }
+@media (min-width: @screen-tablet) and (max-width: @screen-tablet-max) { ... }
+@media (min-width: @screen-desktop) and (max-width: @screen-desktop-max) { ... }
+@media (min-width: @screen-large-desktop) { ... }
