 You can render data collections directly using Rails-like partial rendering. When you call `render` on a data collection, Perron will automatically render a partial for each item.
 ```erb
-<%= render Perron::Site.data.features %>
+<%%= render Perron::Site.data.features %>
 ```
 
 This expects a partial at `app/views/content/features/_feature.html.erb` that will be rendered once for each feature in your data file. The individual record is made available as a local variable matching the singular form of the collection name.
 ```erb
 <!-- app/views/content/features/_feature.html.erb -->
 <div class="feature">
-  <h4><%= feature.name %></h4>
-  <p><%= feature.description %></p>
+  <h4><%%= feature.name %></h4>
+  <p><%%= feature.description %></p>
 </div>
 ```
