Using a custom domain with Tender
Tender allows you to use a custom domain for your installation. Let's say your application lives at http://example.com and you'd like your Tender to live at http://help.example.com. To do this, you'll need to setup a CNAME record with your DNS pointing help.example.com to tenderapp.com.
If you use GoDaddy for your registrar and you use them for DNS hosting (Total DNS), you can follow the steps below to get started:
STEP 1: Under the manage domain screen, click the "Total DNS Control & MX Records" link. If you do not have this link, it means GoDaddy is not controlling your DNS and you'll need to follow different instructions.
STEP 2: Click "Add new CNAME Record" For the Alias name, enter help.example.com, for the points to host name, enter tenderapp.com
STEP 3: Configure your tender to respond to the custom domain. Enter in your custom domain under the Site Settings portion of the admin.
STEP 4: Wait for the DNS to resolve (a few hours) and you should be good to go!
