# Choosing a subdomain

{% hint style="info" %}
Please follow the steps to set a custom domain in this order:

1. [Choosing a custom domain](/store-management/custom-domain/choosing-a-subdomain.md)
2. [Initiating the custom domain setup](/store-management/custom-domain/initiate-customdomain.md)
3. [Configuring DNS](/store-management/custom-domain/configuring-dns.md)
4. [Check DNS](/store-management/custom-domain/check-dns.md)
   {% endhint %}

*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> |      ✅     |

Once you have chosen your custom domain, you're ready to move onto the next step: [Initiating the custom domain setup](/store-management/custom-domain/initiate-customdomain.md)
