 ### **CORS**
 
-When accessing gRPC from a browser via HTTP transcoding or gRPC-Web, CORS headers may be required for the browser to allow access to the gRPC endpoint. Adding CORS headers can be done by using `GRPC.Server.Interceptors.CORS` as an interceptor in your `GRPC.Endpoint` module, configuring it as decribed in the module documentation:
