😊 Welcome! This is either your first contribution to the Istio documentation repo, or
it's been a while since you've been here. A few things you should know:

• You can learn about how we write and maintain documentation, our style guidelines,
  and the available web site features by visiting Contributing to the Docs.

• In the next few minutes, an automatic preview of your change will be built with
  a full copy of the istio.io website. You can find this preview by clicking on
  the Details link next to the deploy/netlify entry in the status section of this
  page.

• We care about quality, so we've put in place a number of checks to ensure our documentation
  is top-notch. We do spell checking, sanitize the Markdown, ensure all hyperlinks point to a
  valid location, and more. If your PR doesn't pass one of these checks, you'll see a red X in the
  lint_istio.io entry in the status section. Click on the Details link to get a list of the
  problems with your PR. Fix those problems and push an update; this will automatically re-run the
  tests. Hopefully this time everything will be perfect!

• Once your changes are accepted and merged into the repository, they will initially show up
  on https://preliminary.istio.io. The changes will be published to https://istio.io
  the next time we do a major release (which typically happens every 3 months or so).
  To publish them sooner, add a cherrypick/release-x.xx label, where x.xx is the current
  release of Istio.

Thanks for contributing!

Hi @Ayush9026. 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.

Hi @craigbox sir,

The changes to archive/v0.8/index.html were unintentional.I will restore the file to its original state and ensure that the unintended changes are corrected.

Thanks, @craigbox! sir I’ll fix the naming issues.

Hi @Ayush9026,

This looks like LLM-generated content which is being submitted in order to influence selection for an upcoming LFX mentorship. Am I wrong?

Please refer back here, especially the section reading "Jumping into issues in the community is a great, but it is very obvious to maintainers when someone is doing it to try to win a paid mentorship."

[istio-testing]

@Ayush9026: The following test failed, say /retest to rerun all failed tests or /retest-required to rerun all mandatory failed tests:

Test name	Commit	Details	Required	Rerun command

Hi sir,

I understand your concern. I am currently working on freelance projects, which involve reviewing and writing content, including an blog. To ensure quality, I structured my content and checked for spelling mistakes. If needed, I can share the template provided for this work.
