        To enable alerting, enable it in the Grafana config:
        <div>
          <pre>
            {`[unified_alerting]
enable = true
`}
          </pre>
        </div>
        <div>
          For legacy alerting
          <pre>
            {`[alerting]
enable = true
`}
          </pre>
        </div>
      </Page.Contents>
    </Page>
  );
