# Add Watermark

RealtimeKit's watermark feature enables you to include an image as a watermark in your recording. To add watermark, configure the following parameters to video\_config in the [Start Recording API](https://developers.cloudflare.com/api/resources/realtime%5Fkit/subresources/recordings/methods/start%5Frecordings/).
