RavenHQ provides access to a number of bundles that can be added to your database to extend it features and functionality. Bundles can be added to new databases as part of the database setup process. Additionally, bundles can be added to existing databases by going to the database details page and selecting "Bundles" under the "Manage Database" heading. This will present the list of available bundles as well as the ones currently installed. Bundle descriptions and documentation links can also be found here.
Please Note: Installing bundles is a one-way operation and can't be undone without contacting RavenHQ support.
The full list of supported bundles can be found here.
