+README FOR THE MAC CARBON PORT
+
+Runs on Mac OS X 10.1 (could also run on 10.0.x, but not tested), and Mac OS 8.6 or later (with CarbonLib
+installed).
+
+HOW TO COMPILE?
+Launch the scummvm.mcp file in CodeWarrior and choose one of the Targets to compile. For just playing,
+you should choose "ScummVM Final", the Debug one is just for Developing.
+Binaries will come up to the Website with the release 0.2.0, which will be hopefully soon.
+
+NOTES:
+Put the games in a folder in the same directory as ScummVM, which have the name of the Data Files, like this:
+
+-- - ScummVM
+  \- monkey2-
+             \- monkey2.000
+              - monkey2.001
+
+
+Hope this will help you :)
+
+CHANGES:
+- Thanks to Florent Boudet, QuickTime MIDI has been added, although it currently only works with DOTT
+- Added SFX Sound Support
+- Now draws the Games Cursors
+
+BUGS:
+- On OS X it got some Problems with KeyDown-Events (seems to work now, most of the time)
+- Bad behaviour of the Application towards other, will be fixed soon.
+- Some minor bugs
+
+If you find any bugs, just make a Bug Report on our SourceForge Page.
