*Only* subdomains can be used to serve your store. It's not possible to use an apex domain.

Here are some examples of what you could and could not choose — just replace `example.com` with your own domain:

| Domain type      | Example                                                                                                       | Supported? |
| ---------------- | ------------------------------------------------------------------------------------------------------------- | :--------: |
| Apex domain      | `example.com`                                                                                                 |      ❌     |
| `www` subdomain  | `www.example.com`                                                                                             |      ✅     |
| Custom subdomain | <p><code>docs.example.com</code></p><p><code>help.example.com</code><br><code>anything.example.com</code></p> |      ✅     |
