Testing every block of code in the README

[tra38]

In commit c83376, you mentioned that it might be good "to test every block of code in the README so that any additional problems like this can be fixed straight away." I'm curious what you mean by that, and so I made this quick issue.

Do you plan on doing the tests manually (just try out every code snippet to make sure it does what it's supposed to do)? Or would all the tests be automated (like doctests)? If so, do you plan on writing out a Markdown parser to extract code blocks from our README and turn them into RSpec tests? Or are there other approaches you're considering?
