title: Purpose of Gitlab "Maintenance Note" for a Runner
body: <p>It's the first time I make a pipeline for CI/CD in Gitlab. At a point, when registering the runner, we can <em>&quot;Enter optional maintenance note for the runner&quot;</em>.</p>
  <p>I looked for more information about it, but I found nothing in GitLab documentation except for <a href="https://about.gitlab.com/handbook/support/workflows/admin_note.html" rel="nofollow noreferrer">Admin Notes</a> and the example in the <a href="https://gitlab.com/gitlab-org/gitlab/-/issues/348299" rel="nofollow noreferrer">issue to add Optional Maintenance Note</a> does not really help me to understand.</p>
  <ul>
  <li>So, what is the purpose of the optional maintenance note ?</li>
  <li>When do we need to look at this message ?</li>
  <li>In the issue, they said it is not for casual user, so is it dedicated only for developers ?</li>
  <li>Also, can you give me an example of what an optional message can be ?</li>
  </ul>
  <p>Thanks !</p>
