How to launch a consumer chain from provider chain? #492

Problem

There is detailed explanation of how CCV works but we don't have any tutorial on how to launch a consumer chain from provider chain. It would be helpful for us if we get a detailed process on how to launch a consumer chain. When will this feature be live on cosmos-hub(gaia)?
