As long as your Brava is connected to wifi you should automatically receive both the recipe updates as well as software updates as they are released.
To check if your Brava is on the latest update, follow these steps:
1. Go to Settings
2. Click on About this Brava
3. Click on Check for Updates
If your Brava is updated with the latest software, the screen should remain the same. Otherwise the Brava will download the latest software.
