Nope! Customers don't have to do any setup. All of it is handled automatically. We use Namecheap's API to forward your root domain to www, and then point your www CNAME to a subdomain on claimyourname. That configuration tells the app which site to serve up.

So it doesn't support root domains? Using a root domain on Herkou requires configuring some non-standard record (I think it is ANAME).

It's something that annoyed me about Heroku because a lot of people prefer the non-www version of their domain as canonical these days.
