+Contributing to KWSys
+*********************
+
+Overview
+========
+
+KWSys is kept in its own Git repository and shared by several projects
+via copies in their source trees.  Changes to KWSys should not be made
+directly in a host project, except perhaps in maintenance branches.
+
+Please visit
+
+  http://public.kitware.com/Wiki/KWSys/Git
+
+to contribute changes directly to KWSys upstream.  Once changes are
+reviewed, tested, and integrated there then the copies of KWSys within
+dependent projects can be updated to get the changes.
+
+Issues
+======
+
+KWSys has no independent issue tracker.  After encountering an issue
+(bug) please try to submit a patch using the above instructions.
+Otherwise please report the issue to the tracker for the project that
+hosts the copy of KWSys in which the problem was found.
+
+License
+=======
+
+We do not require any formal copyright assignment or contributor license
+agreement.  Any contributions intentionally sent upstream are presumed
+to be offerred under terms of the OSI-approved BSD 3-clause License.
+See `Copyright.txt`_ for details.
