OSX

Install everything you need on your laptop, powered by Puppet.

Principles

Testeable: I am not sure yet if this can be tested but I will do my best here. My main concern is to virtualize an OSX environment with Vagrant or Docker.
Idempotent: You can run it as many times you want and the result is still the same.
Scalable: It should use modules so it can be extended easily.

I will probably automate this steps too but for now let's write them down here.

sudo gem install puppet -v 3.8.4
sudo gem install librarian-puppet

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

make install

make dependencies
