To create either a subdomain, an addon domain or a domain alias, follow this four easy steps:
1. Login to the control panel using the link shared with you.
2. Click on the card that has a screenshot and domain you want to add either sub-domain, addon domain or a domain alias.
3. On the page that opens, click on domains as shown bellow on the navigation menu:
4. On the next page, click on the button Add Domain as shown bellow:
5. On the available buttons as pointed out on the screenshot bellow, choose the one that applies to you. If it is a subdomain name, select the subdomain button. If an addon domain, choose the addon domain button, then fill in your domain details in the text area bellow it. In my case I used a subdomain. click the add button at the bottom.
That is all you need to add either a subdomain, an addon domain or a domain alias.
Cheers.
