 A preset is a set of permissions and UI configurations that are applied to participants for different meeting types such as Group Call, Webinar, and Livestream. The presets define how a meeting will appear visually and functional aspects of the meeting. They allow customization options like setting maximum number of participants on-screen, permissions to share screen, enabling poll creation, disabling video and audio, adjusting text color, configuring plugins, etc.
 
+To create a preset, please refer to our Developer Portal's [Presets Section](https://dev.dyte.io/presets).
