+/**
+`google-signin-aware` is used to enable authentication in custom elements by
+interacting with a google-signin element that needs to be present somewhere
+on the page.
+
+The `scopes` attribute allows you to specify which scope permissions are required
+(e.g do you want to allow interaction with the Google Drive API).
+
+The `google-signin-aware-success` event is triggered when a user successfully
+authenticates. If either `offline` or `offlineAlwaysPrompt` is set to true, successful
+authentication will also trigger the `google-signin-offline-success`event.
+The `google-signin-aware-signed-out` event is triggered when a user explicitly
+signs out via the google-signin element.
+
+You can bind to `isAuthorized` property to monitor authorization state.
