 ## Demos
 ### DemoRabbitControl
 
+Demonstrates how to use RabbitControl to create a web-based user interface for your program.
 
+A `settings` object is created using the same syntax used for `orx-gui`, including
+annotations for different variable types.
+
+The program then passes these `settings` to the `RabbitControlServer`. A QR-code is displayed
+to open the web user interface. A clickable URL is also displayed in the console.
+
+Once the UI is visible in a web browser we can use it to control the OPENRNDR program.
