If you're using Shorthand hosting and want to dedicate a subdomain of a domain you already own to your Shorthand stories, you will need to be able to edit CNAME and DNS records listed with your domain registrar (the entity from which you purchased the domain). 

There are many different domain registrars and the method for adding or changing the CNAME records will depend on the provider you use.  

We have compiled a list of some popular domain registrars. Please find yours in this list and refer to their support page:

Please note: DNS validation for domains registered with Godaddy and other registries may fail unless you modify the CNAME values provided by ACM. More information here.
