The document introduces Nokia's Notifications API, which allows developers to implement push notifications in their apps. It provides optimized delivery of notifications to devices using minimal bandwidth. The API offers unlimited design flexibility and can deliver notifications regardless of the app's state. Developers can access the API through the Qt SDK and register apps with the Ovi Notifications service to begin delivering notifications.
