DEV_README.txt

Thank you for your willingness to help make NumPy the best array system
available.
 
We have a few simple rules:
 
 * try hard to keep the Git repository in a buildable state and to not
 indiscriminately muck with what others have contributed.
 
 * Simple changes (including bug fixes) and obvious improvements are
 always welcome. Changes that fundamentally change behavior need
 discussion on numpy-discussions@scipy.org before anything is
 done.
 
 * Please add meaningful comments when you check changes in. These
 comments form the basis of the change-log.
 
 * Add unit tests to exercise new code, and regression tests
 whenever you fix a bug.
