+    <small>This tutorial goes beyond the <a href="tutorial-views.html">basic
+    views tutorial</a> and shows you how to do more with grids</small>
+  </h1>
+</div>
+
+### How much can I do with a simple grid view
+
+### Benefits of SlickGrid
+What does Recline give you out of the box, what does SlickGrid have built in and how to use it (reference to stuff below).
+
+### Preparing your page
+
+See the instructions in the [basic views tutorial](tutorial-views.html).
+
+### Creating a Dataset
+
+Just like in the main tutorial, here's some example data We are going to work with:
+
+{% highlight javascript %}
+{% include data.js %}
+var dataset = new recline.Model.Dataset({
+  records: data
+});
+{% endhighlight %}
+
+<script type="text/javascript">
+{% include data.js %}
+var dataset = new recline.Model.Dataset({
+  records: data
+});
+</script>
+
+### Accessing SlickGrid features
+Show how we can customize SlickGrid grid "normally" - i.e. you can get access to underlying grid and tweak it as you want.
+
+Suggest we demonstrate using this example: https://github.com/mleibman/SlickGrid/blob/gh-pages/examples/example-plugin-headermenu.html
+
+Idea here is: we don't want to mimic all that slickgrid can do through recline interface - just let people do it directly themselves ...
