+# Facebook Graph Example
+
+The Facebook Graph API is a great example of how powerful RemoteModel is. Facebook auth code adapted from [facebook-auth-ruby-motion-example](https://github.com/aaronfeng/facebook-auth-ruby-motion-example)
+
+## Running
+
+You need [motion-cocoapods](https://github.com/HipByte/motion-cocoapods) installed to load the Facebook iOS SDK. 
+
+It also appears that (as of May 9 2011), motion-cocoapods doesn't play nice with the FB SDK and you need to use `rake --trace` to get it to load correctly.
+
+You need to specify an FB app ID, which you can create [in FB's Developer app](https://www.facebook.com/developers):
+
+###### app_delegate.rby
+
+```ruby
+def application(application, didFinishLaunchingWithOptions:launchOptions)
+  ...
+  @facebook = Facebook.alloc.initWithAppId("YOUR-APP-ID", andDelegate:self)
+  ...
+end
+```
+
+###### Rakefile
+
+```ruby
+Motion::Project::App.setup do |app|
+  ...
+  fb_app_id = "YOUR-APP-ID"
+  app.info_plist['CFBundleURLTypes'] = [{'CFBundleURLSchemes' => ["fb#{fb_app_id}"]}]
+  ...
+end
