+This code example uses a view engine that uses the Handlebars rendering engine.
+Thus, you are required to install Handlebars with npm for the example to work.
+
+Before you run the application, please run the following command:
+
+`$ npm install handlebars`
+
+From the application directory, you should see that a `node_modules` directory with Handlebars has been created:
+
+    node_modules
+    └── handlebars
+        ├── LICENSE
+        ├── README.markdown

+        ├── lib
+        ├── node_modules
+        └── package.json
