-The process is common to all supported languages, and it follows the usual OTel Operator steps for [auto-instrumentation injection](https://github.com/open-telemetry/opentelemetry-operator#opentelemetry-auto-instrumentation-injection):
-
-  1. Install the OTel Operator into a k8s cluster.
-  2. Create a `kind: Instrumentation` object with the appropriate config.
-  3. Deploy a pod or deployment with the appropriate annotation.
