+## ⚠️ Deprecation Notice ⚠️
+This repository is no longer actively maintained. We are in the process of moving all instrumentation packages to the [opentelemetry-js-contrib](https://github.com/open-telemetry/opentelemetry-js-contrib) repository.
+
+For the latest updates and contributions, please refer to the respective packages in the `opentelemetry-js-contrib` repository. We recommend transitioning your projects to use the instrumentation packages from the new repository.
+
+Thank you for your understanding and continued support!
