Very well written.

That was super quick. I am able to connect my main domain and it started working rightaway. Thanks. Only request is I can't find any doc/process to link sub-domain www also to my blog? My main domain is ideaman.io and I also want to link www.ideaman.io to the same blog.

This is one of the best hack I read.
