+**_WARNING:_** Until the OpenTelemetry Collector format is stable, changes may be required in the above example to remain
+compatible with the latest version of the OpenTelemetry Collector image being referenced.
 
 This will create an OpenTelemetry Collector instance named `simplest`, exposing a `jaeger-grpc` port to consume spans from your instrumented applications and exporting those spans via `logging`, which writes the spans to the console (`stdout`) of the OpenTelemetry Collector instance that receives the span.
