Want to serve your website on your very own custom domain name? You can do that! There are easy ways to either a) connect a particular project repository to a domain name or sub-domain name or b) wire up your GitHub account so that any repo you create and serve off GitHub pages automatically is served on that custom domain. Here we're going to explore how to do the former:
Step 1: Buy a domain name at your domain vendor of choice, like namecheap.com - and login to the dashboard for that vendor.
Step 2: Follow the steps in GitHub's documentation on configuring an apex domain. If you'd like to use a subdomain of the domain name you just bot (like blog.sampledomain.com) there are instructions on configuring a subdomain as well.
Step 3: Reflect. Now that you've followed the instructions and (hopefully) got it working. It might be a good time to put the inquisitive skills that you learned in class to use and build a mental model of what you just did. What is an "A record"? What is a "CNAME"?
