+Hello License Python
+====================
+
+Overview
+--------
+This application implements a sample client for the Chrome Web Store Licensing
+API on Google's Python App Engine service.
+
+For information about this API, please see:
+http://code.google.com/chrome/webstore/
+
+Usage
+-----
+First, register an App Engine app at www.appspot.com.  Make sure you select
+Federated Login as the login provider for the app.
+
+You'll need to configure this sample before it will be functional.  Edit
+app.yaml and replace the text INSERT APPLICATION NAME HERE with the application
+identifier you registered.
+
+Second, obtain a token for the Chrome Web Store license server.  Check the
+license server documentation for instructions on how to do this.  Edit main.py
+and replace the following three configuration lines with your own information:
+
+  'oauth_token': 'INSERT OAUTH TOKEN HERE',
+  'oauth_token_secret': 'INSERT OAUTH TOKEN SECRET HERE',
+  'app_id': 'INSERT APPLICATION ID HERE',
+
+Then deploy your application to App Engine, and you will be able to log in
+with OpenID and check the license status of your account.
