+<Warning>
+We recommend using [Weave's new OTel-native workflow](/weave/guides/tracking/trace-agents-otel) to send OTel spans to Weave's new Agents view. Only use this guide if you want to send raw OTLP trace ingestion into Weave's standard Traces view.
+</Warning>

 Weave supports import of OpenTelemetry compatible trace data through a dedicated endpoint. This endpoint lets you send OTLP (OpenTelemetry Protocol) formatted trace data directly to your Weave project. Use this integration when you want to instrument your application with the OpenTelemetry standard and have those traces appear alongside your other Weave data, without replacing your existing OTel-based observability pipeline.
 
 This page covers the endpoint details, authentication, end-to-end examples in Python and TypeScript, how to forward traces through an OpenTelemetry Collector, how to organize traces into Weave threads, and the attribute mappings Weave applies to incoming spans.

-W&B Weave agent observability is built on [OpenTelemetry (OTel)](https://opentelemetry.io/docs/concepts/). Weave provides a dedicated OTLP endpoint that ingests spans into the **Agents** view. If your agent already emits OTel spans, you can send them to Weave by pointing your existing OTel pipeline at the endpoint without installing the Weave SDK.
+W&B Weave agent observability is built on [OpenTelemetry (OTel)](https://opentelemetry.io/docs/concepts/) and provides a dedicated OTLP endpoint that ingests spans into the **Agents** view. This means that you can quickly redirect your OTel-instrumented application's spans to Weave by swapping your OTel exporter's current endpoint configuration with Weave's endpoint configuration. You do not need to install the Weave SDK to do this.
 
 This page covers how to authenticate with and send spans to the endpoint.
