Need simple instructions or wrapper script

[willsheppard]

I don't have the book. Also I don't speak Spanish. But I would like to run the koans to learn node.

Other koans repos include a command or script to execute the koans so that a complete beginner can easily see how to proceed:

• https://github.com/willsheppard/python_koans
• https://github.com/willsheppard/ruby_koans

Could something similar be added to this repo?
