+### :mega: OpenTelemetry Python with AWS X-Ray
+
+AWS X-Ray recommends using AWS Distro for OpenTelemetry (ADOT) to instrument your application **instead of this X-Ray SDK** due to its wider range of features and instrumentations. See the [AWS X-Ray docs on Working with Python](https://docs.aws.amazon.com/xray/latest/devguide/xray-python.html) for more help with choosing between ADOT and X-Ray SDK.
+
+**NOTE**: OpenTelemetry Python **does not currently support Centralized Sampling**, only the X-Ray SDK does, but we hope to have this feature in OTel in the future.
+
+If you want additional features when tracing your Python applications, please [open an issue on the OpenTelemetry Python Instrumentation repository](https://github.com/open-telemetry/opentelemetry-python-contrib/issues/new?labels=feature-request&template=feature_request.md&title=X-Ray%20Compatible%20Feature%20Request).
