+    <p>Recline has a simple structure layered on top of the basic Model/View
+    distinction inherent in Backbone. There are the following three domain objects (all Backbone Models):</p>
+    <ul>
+      <li>Dataset: represents the dataset. Holds dataset info and a pointer to list of data items (Documents in our terminology) which it can load from the relevant Backend.</li>
+      <li>Document: an individual data item (e.g. a row from a relational database or a spreadsheet, a document from from a document DB like CouchDB or MongoDB).</li>
+      <li>Backend: provides a way to get data from a specific 'Backend' data source. They provide methods for loading and saving Datasets and individuals Documents as well as for bulk loading via a query API and doing bulk transforms on the backend</li>
+    </ul>
+    <p>There are then various Views (you can easily write your own). Each view holds a pointer to a Dataset:</p>
+    <ul>
+      <li>DataExplorer: the parent view which manages the overall app and sets up sub views.</li>
+      <li>DataTable: the data grid / table view.</li>
+      <li>FlotGraph: a simple graphing view using <a href="http://code.google.com/p/flot/">Flot</a>.</li>
+    </ul>
