Learn to bind a custom domain.
What is a custom domain?
A custom domain means the site is published under your own domain name. To link a domain like www.ornek.com to the site you set up DNS records and tell GitHub about it. This notice is given with a CNAME file.
echo "www.ornek.com" > CNAMEThe CNAME file
The CNAME file contains the custom domain where the site will be published. This file sits in the root folder of the publish branch. The DNS pointing must also connect the domain to GitHub servers.
cat CNAME
www.ornek.comThe file content contains only the domain name.
Practice Create the CNAME file
Create index.html and save it quietly. Then create a CNAME file containing the domain www.ornek.com, add it and save quietly. Print the contents of the CNAME file.
