+### Using OpenTelemetry tracing
+
+Kaoto-backend provides OpenTelemetry tracing. By default, OpenTelemetry SDK Autoconfigure is disabled.
+It can be enabled by `quarkus.otel.sdk.disabled=false` 
+Note that after that, the OTLP Exporter (e.g. Jaeger) is expected on `http://localhost:4317/` but the endpoint can be overridden via `quarkus.otel.exporter.otlp.traces.endpoint` configuration property.
+For more information and all configuration properties, see [Quarkus OpenTelemetry guide](https://quarkus.io/guides/opentelemetry)
+
+### CORS
+
+[CORS filter](https://quarkus.io/guides/http-reference#cors-filter) is enabled by default.
+For proper functionality with the Kaoto-ui, it is necessary to set `quarkus.http.cors.origins` configuration property with Kaoto-ui URL(s).
+For more information and all configuration properties, see [Quarkus HTTP Reference](https://quarkus.io/guides/http-reference#quarkus-vertx-http-config-group-cors-cors-config_configuration)
+
+Note: When you run Kaoto-backend in the dev mode, all origins are accepted.
