export const AdminOnly = () => <Info>

<Warning>
  Changing the subdomain breaks existing referral links already shared with
  customers. Only change it if you are sure you need to.
</Warning>

The value must be 1-30 characters: lowercase letters, numbers, and hyphens, ending with a letter or number. Status badges include **Not set**, **Checking availability...**, **Available**, **Unavailable**, and **Saved**.

<Steps>
  <Step title="Open Domain">Go to **Settings > Domain**.</Step>

  <Step title="Enter the Subdomain">
    Type the subdomain in the field. The suffix `.mention-me.com` is added for
    you.
  </Step>

  <Step title="Confirm">
    Click **Save Changes**. Confirm in the dialog by typing the current
    subdomain, then click **Set subdomain** or **Change subdomain**.
  </Step>
</Steps>

This is the customer-facing referral host. It is separate from the workspace slug on **Settings > General**, which only affects `app.mention-me.com/...` URLs.
