An addon domain lets you host a completely separate website under the same hosting account.

1. Log in to cPanel.
2. Go to Domains > Domains (or Addon Domains in older versions).
3. Click Create A New Domain.
4. Enter the new domain name. cPanel fills in the document root folder automatically.
5. Click Submit.

Upload that site's files to the new folder (usually under public_html/yourdomain).

Note: The addon domain must already be registered and pointed to our nameservers (article 41) to display your site.
