 If you want to set the `display` format or `scope` on a per-request basis, you can just pass it to the OmniAuth request phase URL, for example: `/auth/facebook?display=popup` or `/auth/facebook?scope=email`.
 
-You can also pass through a `state` param which will be passed along to the callback url.

 ### Custom Callback URL/Path
 
 You can set a custom `callback_url` or `callback_path` option to override the default value. See [OmniAuth::Strategy#callback_url](https://github.com/intridea/omniauth/blob/master/lib/omniauth/strategy.rb#L411) for more details on the default.
