Custom domains
If you want to use a custom domain, add a CNAME record in your DNS provider to point to the correct deployment. For example:
www.mydomain.com CNAME myServer.branch.repo.org.garnix.me
Some providers allow CNAMEs in apex domains (via CNAME flattening), others do not. garnix will work with the former.
garnix will generate TLS certificates on the fly for your custom domain on the first request!
