I wanted to use nomad, but at the time their tutorials (not sure about their current state) were not really good, so I ended up rolling my own solution which serves me well since then (https://github.com/crufter/puller).
I agree about lack of tutorial or documentation. Hashicorp documentation always feels like an internal wiki company wiki or a reference guide for someone who is already quite familiar with the APIs. I just checked the Nomads docs and it looks pretty much like it did when I looked at it 4 or 5 months ago.
