Hi @jichenjc. Thanks for your PR.

I'm waiting for a metal3-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

@jichenjc I just noticed there are few more places in the same documentation where it needs an update in terms of API versions(all CAPI objects should have v1alpha4 and CAPM3 objects v1alpha5 API versions). It would be great, if you could take care of updating those in the same PR.

@furkatgofurov7 updated again :)

Thanks, there is only one mention of API for Metal3Cluster that is left still in line 131 that needs an update.
