A custom domain lets you use your own address, like yournamehere.com, or blog.yournamehere.com, with your Posthaven blog.
Set up an A record from your domain name name server to the IP address: 18.104.22.168
If your domain name is not a top level domain (e.g. not foobar.com) and does have a hostname (e.g. blog.foobar.com) then you can set up a CNAME to: posthaven.com
Go to your Dashboard and hit "Settings" on your site. Click on "Setup custom domain."
Then enter your site into the custom domain field.
Save, and you should be ready to rock.
Keep in mind that DNS is heavily cached so changes can take hours (or in some cases up to a day) to show up in your browser.
