Setting Up A Windows Workstation for Chef Development - The Easy Way

This is based on Steve Murawskis work. See his blog post on simplified-chef-workstation

What I really really want is ... using boxstarter instead of chocolatey:)

Nice work , agree with you to use boxstarter, if you need some help ping me !

You can use powershell_package resource instead of powershell_script.
https://github.com/chef/chef/blob/master/lib/chef/resource/powershell_package.rb

powershell_package 'PSReadline' do
  action :install
end
