Followed the official Github docs for Managing a custom domain for your Github Pages site.
- added my custom domain in the repo settings
- the dns check will fail for now, since the CNAME record hasn’t been added
- edit the CNAME record for the
www
subdomain to point to my github pages site - wait…
- the next day, confirmed that ‘www.lillchan.com’ was pointing to my github pages site
dig www.lillchan.com
