+Removing a user from the database proved to be a little tricky, so we add these helper functions in server.coffee to make dealing with the database easier.

+    newContact = new @app.Contact

+### Routing server-side
+
+Ember-data expects the json wrapped in an object with the model name, so we set up our router like so:
 
+```coffee
+  @get '/': ->
+    @app.Contact.find({}, (err, docs) =>
+      Contacts = {}
+      @Contacts = Contacts: docs
+      @send @Contacts
+      )
+```
 
+Notice we use the fat arrow here so we can retain the value of 'this' in our callback.
