| Record | Name | Value | Why |
|---|---|---|---|
| TXT | _docsbuilder.docs.customer.com | the token shown | Proves they own the domain |
| CNAME | docs.customer.com | your CNAME target | Sends visitors to your platform |
A bare domain (customer.com) can't have a CNAME record, so they use an ALIAS or flattened CNAME record, or an A record to your server's address if you give one in the admin. A subdomain is always simpler.
JustDocs checks new domains every few minutes, then less often. Each domain moves through Waiting for DNS → Connecting → Getting certificate → Live, and when something is wrong the customer sees a plain explanation, such as "points to X, not Y". Check connection runs the check straight away. A domain is only used for canonical links and the sitemap once it's Live, which means it answers over HTTPS and leads to your install.
