A sub-domain is a third-level domain that lets you manage your website folders in such a way that users will easily access it via a special URL access.

As long as your account permits, you can create as many sub-domains as you want by following these steps:

1. Log in to the Helm control panel.

2. In the control panel, click the “My Domains” icon.

3. The “Domains” page should appear shortly. This is where you can manage or control sub-domains in your account.

4. Then click the “Sub Domains” icon on the page.

5. You will be directed to the “Sub Domains” page. If there are currently installed sub-domains in your account, sub-domains should appear on the list.

6. To continue creating the sub-domain, click “Add.”

7. Enter the sub-domain name that you prefer to use in the “Sub Domain Name” text field.

8. After you are done with step 7, click the “Save” button.

9. The later sub-domain will then be included in the list of your sub-domains if you have successfully created it.

10. You can always return to this “Sub Domains” page whenever you desire to add, modify or delete sub-domains that are available in your account.
