Document production setup a bit more

[jtolio]

Right now the README appears mostly geared to running on localhost. There is a small bit for production setup but it says "More to come here..."

Looking forward to the more to come!

Please, we need this because want to deploy it in production environment.
Do you plan to add it soon? Can we help in some way?

Thank you!
