How do I use my own domain?

You can setup a subdomain on your domain (ex: delivery.mysite.com), and then setup your Quixly account to be accessible at that address. To make it all happen you will need to setup a CNAME record with your DNS pointing delivery.mysite.com to quixly.com. You will be able to edit your DNS with your host. So login to your hosting account to do this.
Here's how using GoDaddy:

• Create a subdomain to be used with Quixly on your website. Example: delivery.mysite.com
• Login to your GoDaddy account and bring up your domain in the "Domain Manager".
• Click on the "Total DNS Control" link on the domain manager page.
• Click the "Add New CNAME Record" button.
• Enter the URL you setup into the "Enter an Alias Name" field. Example: delivery.mysite.com
• Enter: quixly.com into the "Points To Host Name" field and click "Ok".
• In a new window, navigate and login to your Quixly account and click on the "Account" tab.
• Enter the URL you setup into the "Custom Domain Name" field in the "Custom Branding" section. Example: delivery.mysite.com
  Do NOT include the http:// in the URL.
• Click save, and your done!
