 Currently supports:
 
  * Generation of model classes based on an XML schema (not YAML) placed under `BundleName/Resources/*schema.xml`.
- * Propel runtime initialization through `$container->getPropelService()`.
+ * Runtime autoloading of Propel and generated classes

+### Sample Schema
+
+Place the following schema in src/Application/HelloBundle/Resources/config/schema.xml:
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <database name="default" package="Application.HelloBundle.Model" defaultIdMethod="native">
+
+      <table name="book" namespace="Application\HelloBundle\Model">
+        <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" />
+        <column name="title" type="varchar" primaryString="1" size="100" />
+        <column name="ISBN" type="varchar" size="20" />
+        <column name="author_id" type="integer" />
+        <foreign-key foreignTable="author">
+          <reference local="author_id" foreign="id" />
+        </foreign-key>
+      </table>
+
+      <table name="author" namespace="Application\HelloBundle\Model">
+        <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" />
+        <column name="first_name" type="varchar" size="100" />
+        <column name="last_name" type="varchar" size="100" />
+      </table>
+
+    </database>
+
+### Build Process
+
+Call the application console with the `propel:build` task:
+
+    > ./hello/console propel:build --classes
+
+### Use The Model Classes 
+
+Use the Model classes as any other class in Symfony. Just use the correct namespace, and Symfony will autoload them:
+
+    class HelloController extends Controller
+    {
+      public function indexAction($name)
+      {
+        $author = new \Application\HelloBundle\Model\Author();
+        $author->setFirstName($name);
+        $author->save();
+
+        return $this->render('HelloBundle:Hello:index', array('name' => $name, 'author' => $author));
+      }
+    }
+
