+> **Note**: The [default configuration](https://github.com/distribution/distribution/blob/main/cmd/registry/config-dev.yml)
+> is designed for development. As such, the log level is set to `debug`. In
+> addition, the registry uses [OpenTelemetry](https://opentelemetry.io/docs/what-is-opentelemetry/)
+> for logs and trace. OpenTelemetry integration is configured using [standard
+> environment variables](https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/),
+> and will by default attempt to export telemetry traces to an OTLP collector at
+> `localhost:4318`. If this is not desired, telemetry can be disabled by adding
+> `-e OTEL_TRACES_EXPORTER=none` to the `docker run` command above.
