 We use [AutoMapper](http://automapper.org/) to map from the model class to the resource class. 
-The below snippet shows how you can specify a custom mapping expression in your `Startup` class that will append `_1` to the resource name.
+The below snippet is a trivial example of how you can specify a custom mapping expression in your `Startup` class.
+In this example, the first and last name are concatenated and used for the value of the resource's DisplayName property.
