+**🎉 New**:
+Our semantic conventions are now part of OpenTelemetry! Join the [discussion](https://github.com/open-telemetry/community/blob/1c71595874e5d125ca92ec3b0e948c4325161c8a/projects/llm-semconv.md) and help us shape the future of LLM observability.
+
 OpenLLMetry-JS is a set of extensions built on top of [OpenTelemetry](https://opentelemetry.io/) that gives you complete observability over your LLM application. Because it uses OpenTelemetry under the hood, it can be connected to your existing observability solutions - Datadog, Honeycomb, and others.
