 ## Changing Types
 If you're making a change to the `pkg/apis/sensor/v1alpha1` package, please ensure you re-run the K8 code-generator scripts found in the `/hack` folder. First, ensure you have the `generate-groups.sh` script at the path: `vendor/k8s.io/code-generator/`. Next run the following commands in order:
 ```
-$ hack/update-codegen.sh
-$ hack/verify-codegen.sh
-$ hack/update-codeapigen.sh

+$ make codegen
