+## Testing
+
+Our tests are based on [QUnit](http://qunitjs.com/) and PhantomJS; they're both installed when you run `npm install`. At the moment we don't have much in the way of tests, but we're working to fix that. To run on the command line:
+
+    grunt test
+
+If you wish to work interactively with the tests or test your changes:
+
+    grunt server watch
+
+and open `http://localhost:8000/` in your browser
