How to provision the game

...on local machine

First install ansible on your machine. Refer to the docs:

http://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html

Once installed, to provision the game on your local machine (localhost), execute the ansible-playbook command.

ansible-playbook -c local provision-game.yml --become -vv

...in a Vagrant Development Environment

To bring up a local development environment, do the following:

$ vagrant up
