+wip osu editor
+==============
+
+running on linux
+----------------
+
+since the editor requires libbass.so to run, run the wrapper script run.sh instead
+
+running on windows
+------------------
+
+wrapper script isn't written yet, in this case i just copied bass.dll to the project root
+
+roadmap
+-------
+
+- [ ] stacking
+- [ ] fix slider overlap problem
+- [ ] long term:
+  - [ ] new framework
+
+license
+-------
+
+not sure yet, probably gpl
+
+includes code ported from ppy/osu, which is mit-licensed
