Contribution policy for first-time contributors

If you have not yet had a non-trivial PR merged in this repository, you are a first-time contributor here. Welcome!

As a first-time contributor, you can do one of the following:

• Open a single issue describing a problem or proposal, and wait for maintainer feedback before doing anything else. Keep to one open issue at a time.
• Submit a single PR for one of:
  • An open issue labeled good first issue:
    • If there are no such issues, check back later.
    • Link to the issue from your PR description.
      ⚠️ NOTE: issues aren't claimed, reserved, or assigned, so don't ask to be assigned: the first adequate PR wins.
  • A trivial editorial fix (typo, broken link) without an issue; such PRs are accepted at maintainer discretion.

[!IMPORTANT]
You remain a first-time contributor until a non-trivial PR of yours is merged: a merged trivial fix doesn't change your status.

[!CAUTION]
Issue or PR spamming, including repeatedly soliciting feedback through any channel, or otherwise repeatedly disregarding this policy, can result in interaction limits, being blocked, or escalation per the CNCF Code of Conduct.

No documentation file, test, or entry point is named in the issue. First clarify which repository page should contain this policy and confirm the intended wording with a maintainer; done means the approved contribution policy is published in the identified location.
