Collaborative editing connects your browser editor to a backend. Start with [Collaboration integration](https://docs.univer.ai/server/collaboration/browser-integration.md) to run the example and connect your application's identity, permissions, and storage. See [Office Quick Start](https://docs.univer.ai/server/collaboration/quick-start.md) for the browser and server configuration.
