+Exdeath
+-------
+
+Exdeath is a simple, Qt-based utility for applying one or several IPS patches to a Final Fantasy V Advance game image. *You must supply your own game image, and we cannot help you find one.*
+
+Building
+--------
+
+To build Exdeath, you will need Qt 5 and a C compiler.
+
+    $ qmake exdeath.pro
+    $ make all
+
+Copyright
+---------
+
+Exdeath is licensed under BSD-3-Clause. The patches incorporated are not original work but are freely distributable.
