I really think this Ansible role could so with some more documentation. I will try and contribute some when I get it working for my setup.

While we're at it - example repos for deploying and rolling back popular frameworks / languages could really help this project get traction. I'd be happy do contribute examples for php/wordpress, node.js/express and python/django. It's the least I could do considering how great ansistrano has been to me.

Hi @michaelBenin it would be fantastic if you could provide all these examples.
Will you have some time to work on it?

I only need some initial structure on the Wiki side to start contributing here. To coordinate, if needed, feel free to contact me.

Thanks and cheers!
