 ## Contributing / Testing
 
 The testing mechanism allows you to easily test fprettify with any Fortran project of your choice. Simply clone or copy your entire project into `fortran_tests/before` and run `python setup.py test`. The directory `fortran_tests/after` contains the test output (reformatted Fortran files). If testing fails, please submit an issue!
