blog.acme.com points straight at Notra, which issues the TLS certificate and serves the site while your main website stays as it is.

Add the domain
Open the site’s Domains page, click Add domain, enter
blog.acme.com and click Add domain, and the domain shows up with the status Needs DNS.2
Add the DNS records
Click the domain to see its records, and add every one at the provider that manages DNS for
acme.com. The dashboard shows full names like _notra.blog.acme.com, so if your provider appends acme.com itself, enter only the part before it:If the dashboard lists one more
TXT record for the certificate, add it too.3
Check the domain
Click Check, and Notra looks up the ownership record first and then waits for DNS and the certificate. DNS changes usually show up within a few minutes but can take longer at some providers, so click Check again until the domain is Active.
https://blog.acme.com/blog/.... To drop /blog from the URL, set the blog path to / under Settings → Content → Sections. See Section paths.
One-click setup
If Notra can add the records for you, a Connect with button with your provider’s name appears above the records. You sign in at your provider, review the records and approve, and the provider adds them and sends you back to Notra, which checks the domain right away. This only creates records on your subdomain, and if the button isn’t there, add the records by hand.Statuses
The domain’s Last check details say which record is missing or wrong.
Root domains
A root domain likeacme.com can’t have a CNAME at most DNS providers, so use a subdomain like blog.acme.com or keep your website on acme.com and forward a path to Notra. If your provider supports CNAME flattening (Cloudflare does), you can choose Point the whole domain to Notra instead in the Add domain dialog.
Troubleshooting

The
_notra record is missing or has a different value. Some providers add your domain to the name automatically, so enter _notra.blog rather than _notra.blog.acme.com if the provider appends acme.com itself. Check what’s live with dig TXT _notra.blog.acme.com +short.The domain stays on Verifying

Notra can’t issue the certificate yet. Make sure the CNAME points to
cname.notra.site, that it isn’t proxied (Cloudflare’s orange cloud) and that no other A, AAAA or CNAME record exists for the same name.I see an old version after the domain went active

Notra rebuilds the site for the new address, and the previous version stays live until that build is done, usually within a minute. Follow it under Deployments.
