First, I change the nameservers of my domain to Cloudflare. I then test that the nameservers are set correctly by running the following command:
λ dig example.com +nostats +nocomments +nocmd
example.com. 600 IN SOA ignat.ns.cloudflare.com. dns.cloudflare.com. 2373316940 10000 2400 604800 1800`
λ dig example.com +nostats +nocomments +nocmd
example.com. 600 IN SOA ignat.ns.cloudflare.com. dns.cloudflare.com. 2373316940 10000 2400 604800 1800`
λ dig example.com +nostats +nocomments +nocmd
example.com. 600 IN SOA ignat.ns.cloudflare.com. dns.cloudflare.com. 2373316940 10000 2400 604800 1800`
λ dig example.com +nostats +nocomments +nocmd
example.com. 600 IN SOA ignat.ns.cloudflare.com. dns.cloudflare.com. 2373316940 10000 2400 604800 1800`
Verifying the ownership of the domain on GitHub
Under "Setting > Pages", I add the custom domain example.comexample.com and verify the ownership of the domain by adding a TXT record in Cloudflare DNS settings.
Configuring the GitHub Pages
In the GitHub repository settings, I change the custom domain to www.example.comwww.example.com. Then, goto the Cloudflare DNS settings and add a CNAME record for wwwwww pointing to myriad-dreamin.github.iomyriad-dreamin.github.io. Noted that the record shouldn't be "Proxied" but "DNS Only". Test that the nameservers are set correctly by running the following command:
λ dig www.example.com +nostats +nocomments +nocmd
www.example.com. 300 IN CNAME myriad-dreamin.github.io.
myriad-dreamin.github.io. 3600 IN A x.x.x.x
λ dig www.example.com +nostats +nocomments +nocmd
www.example.com. 300 IN CNAME myriad-dreamin.github.io.
myriad-dreamin.github.io. 3600 IN A x.x.x.x
λ dig www.example.com +nostats +nocomments +nocmd
www.example.com. 300 IN CNAME myriad-dreamin.github.io.
myriad-dreamin.github.io. 3600 IN A x.x.x.x
λ dig www.example.com +nostats +nocomments +nocmd
www.example.com. 300 IN CNAME myriad-dreamin.github.io.
myriad-dreamin.github.io. 3600 IN A x.x.x.x
The blog finally should be accessible at www.example.comwww.example.com.
