I want to mess with Ubuntu Juju, how do I get started?
Getting started with a Amazon AWS account is very simple, or there is also directions to deploy test instances to local lxc containers, a third more in-depth option is to setup a MAAS (Metal As A Service) first as described also in the docs.
The Getting Started section tells you how to install it and where to input your AWS access-key and secret-key. If you choose the easier AWS route, which go in your
~/.juju/environments.yaml file, if not those are not required but the other keys mentioned are.
After that, start with the tutorial to deploy a sample Wordpress instance and it will be fully up and running in a matter of minutes if your successful.
