+
+Running the automated tests
+===========================
+
+The Unity Test Tools contains a tool called the Platform Runner which builds and runs all the test scenes automaticaly.
+Unfortunately it only works on Windows :(
+
+On OSX you can open each test scene individually and use the Unity Test Runner window to run all tests in each scene.
+
+On Windows:
+1. Open the Platform Runner via Unity Test Tools > Platform Runner
+2. Select the platforms and test set you wish to run.
+3. Run the tests and wait for the results.
