 # Rack::Passbook
 
-> This is still in early stages of development, so proceed with caution when using this in a production application. Any bug reports, feature requests, or general feedback at this point would be greatly appreciated.

 [Passbook](http://www.apple.com/ios/whats-new/#passbook) is an iOS 6 feature that manages boarding passes, movie tickets, retail coupons, & loyalty cards. Using the [PassKit API](https://developer.apple.com/library/prerelease/ios/#documentation/UserExperience/Reference/PassKit_Framework/_index.html), developers can register web services to automatically update content on the pass, such as gate changes on a boarding pass, or adding credit to a loyalty card.
 
 Apple [provides a specification](https://developer.apple.com/library/prerelease/ios/#documentation/PassKit/Reference/PassKit_WebService/WebService.html) for a REST-style web service protocol to communicate with Passbook, with endpoints to get the latest version of a pass, register / unregister devices to receive push notifications for a pass, and query for passes registered for a device.
 
-This project is an example implementation of this web service specification in Rails, and will serve the basis for a more comprehensive Rails generator in the near future.
+Rack::Passbook provides those specified endpoints.
