+## How to Build
+
+If you clone or fork this repo, please update `common.xcconfig` with your development team identifier. Code signing is required to run on iOS, but it's currently disabled for macOS.
+
 ## Limitations
 
 - The UI does not expose a way to configure the scheduler, number of inference steps, or generation seed. These are all available in the underlying code.
