It's a chef recipe

Install zsh package and use the oh-my-zsh plugin to configure zsh

You can define it by configure like :

[:oh_my_zsh][:users] = [{
  :login => 'shingara',
  :theme => 'rachel',
  :plugins => ['gem', 'git', 'rails3', 'redis-cli', 'ruby'],
  :home => '/home/shingara' # optional
}]

note: if home not specified, the recipe will looking for home in /etc/passwd, but this not working for new created users. [see #4]

If you are behind firewall or proxy, also configure this :

[:oh_my_zsh][:repository] = "https://github.com/robbyrussell/oh-my-zsh.git"
