Docs needs updates

[engmsaleh]

What happened:
I tried to deploy WordPress as described in the README & Hosted docs using
helm upgrade -i mysite presslabs/wordpress-site --set 'site.domains[0]=www.example.com'
But it gives error no matches found: site.domains[0]=example.com and as I see the presslabs/wordpress-site seems to be deprecated or not maintained anymore and I don't see it on the current repos

What you expected to happen:
It should deploy the Wordpress correclty

How to reproduce it (as minimally and precisely as possible):
Run the Commands from the README

Anything else?:
I love your setup and I need it to get up and running :(
