Hi @ayushrakesh. Thanks for your PR.

I'm waiting for a istio 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.

Please fix the lint failure.

[kfaseela]

@ayushrakesh you have to fix the lint failure in your document. The error can be seen at https://prow.istio.io/view/gs/istio-prow/pr-logs/pull/istio_istio.io/15305/lint_istio.io/1803333939767545856 , closing the PR and raising a new one will not fix the error

[ayushrakesh]

@kfaseela Yes , I am fixing it.

[kfaseela]

you need not close the PR, you can raise a new revision of the PR after fixing

[ayushrakesh]

@kfaseela I have raised a new PR.

[kfaseela]

@kfaseela I have raised a new PR.

what is the need for raising new PR everytime? why can't you revise existing PR?
