 !!! warning "This feature is flagged as experimental"
     Experimental features might be changed or even removed at any time.
 
-Renovate supports OpenTelemetry which is an emerging monitoring standard.
+Renovate partially supports OpenTelemetry, the emerging monitoring standard.
 
-OpenTelemetry supports three types of observability data:
+OpenTelemetry has three types of observability data:
 
 - traces
 - metrics
 - logs
 
-Renovate can only send traces and only via the OpenTelemetryProtocol (OTLP), other observability data or transfer protocols are not supported.
+## Limitations
+
+While OTLP support traces, metrics, and logs, Renovate only supports traces.
+This means Renovate does not support other observability data like: stats on caching, error events, number of found updates, and so on.
+
+Renovate uses [`@opentelemetry/exporter-trace-otlp-http`](https://www.npmjs.com/package/@opentelemetry/exporter-trace-otlp-http) under the hood.
+This means that Renovate sends traces via [OTLP/HTTP](https://opentelemetry.io/docs/reference/specification/protocol/otlp/#otlphttp) in JSON-encoded protobuf format only.
 
 ## Usage
 
-To activate the instrumentation, the environment variable `OTEL_EXPORTER_OTLP_ENDPOINT` has to be set.
-This sets the endpoint where to send the telemetry data.
-If this endpoint is set, all other environment variables defined by the [OpenTelemetry specification](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/sdk-environment-variables.md) are supported.
+To activate the instrumentation, you must set the `OTEL_EXPORTER_OTLP_ENDPOINT` environment variable.
+This variable controls the endpoint for the telemetry data.
+Once this endpoint is set, you can use all environment variables listed in the [OpenTelemetry specification](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/sdk-environment-variables.md).
+
+## Debugging
 
-For debugging purposes the telemetry can also be printed to the console if the environment variable `RENOVATE_TRACING_CONSOLE_EXPORTER` is set.
+To help you debug, you can print the telemetry to the console.
+Use the environment variable `RENOVATE_TRACING_CONSOLE_EXPORTER`.
