A site can answer on one or more hosts, such as docs.example.com. The primary host is the one readers end up on; other hosts redirect to it.
Overview of the steps
- Your platform maps the host to the site.
- You point the host's DNS at the NextDocs server.
- NextDocs obtains an HTTPS certificate automatically.
Some hostnames are reserved for the NextDocs platform itself and cannot be mapped to a site.
