-    - PR #18: Adding an example of using prop_check with the `test-unit` testing framework to the README. Thank you, @niku!
-    - PR #17, #18, #21: fixing typos in various parts of the documentation. Thank you, @meganemura, @niku and @harlantwood!

 ## What is PropCheck?
 
 PropCheck is a Ruby library to create unit tests which are simpler to write and more powerful when run, finding edge-cases in your code you wouldn't have thought to look for.
