Configure Netlify site to answer to asciidoc.org
As the first step towards domain transfer and site rollout, we need the asciidoc Netlify site to answer to asciidoc.org (even before we point the DNS for asciidoc.org to Netlify). This entails:
- Adding a new custom domain named asciidoc.org
- Setting this domain as the primary domain
We're also going to need HTTPS/TLS set up for this domain using Let's Encrypt. However, I think that may require verifying the DNS for the domain first, and that won't be possible until the domain is transferred. But we can at least set up the custom domain so we can test that Netlify itself is ready to respond to asciidoc.org when we point the DNS to it.
