+subtext: |
+  If you are using the file log receiver, you can now create the same resource attributes as traces (via OTLP) received
+  from an application instrumented with the OpenTelemetry Operator -
+  simply by adding the `extract: { operator_rules: { enabled: true } }` configuration to the `k8sattributesprocessor` processor.
