+## Felix Modifications
+
+This is a snapshot of upstream Marlin from 20150301 modified to be
+used directly with Felix Electronic Boards and Printers. Dual-Head
+has been activated but is not tested. Neither are LCD and SDCARD
+since Ocotprint is in use here. A pull-request to have direct
+upstream hardware support has already been submitted.
