-* Approvers are automatically assigned based on the [CODEOWNERS](./CODEOWNERS) file.
+* Reviewers are automatically assigned via the load-balancing algorithm using contributors from the ovn-org/ovn-kubernetes-members team.
+* Reviewers may opt out of reviewing of any PR or the reviewing process altogether by contacting committers or setting their github profile status as "busy" and removing themselves from any currently assigned PR.
 * Reviewers should wait for automated checks to pass before reviewing
 * At least 1 approved review is required from a maintainer before a pull request can be merged
 * All CI checks must pass

   * A maintainer may choose to carry a PR forward on their own, but they should ALWAYS include the original author's commits
