+# dupeguru-cocoa
+
+This is the Cocoa UI for [dupeGuru][dupeguru]. This code was previously directly in the main repo,
+but since I'm not planning on supporting MacOS myself any longer, I'm splitting it out.
+
+Also, to make the job easier on a would-be maintainer for the Cocoa UI of dupeGuru, I'm planning
+on restoring the XCode/XIB version of the UI from the grave.
+
+### OS X maintainer wanted
+
+My Mac Mini is already a couple of years old and is likely to be my last Apple purchase. When it
+dies, I will be unable maintain the OS X version of moneyGuru. I've already stopped paying for the
+Mac Developer membership so I can't sign the apps anymore (in the "official way" I mean. The
+download is still PGP signed) If you're a Mac developer and are interested in taking this task,
+[don't hesitate to let me know][contrib-issue].
+
+## How to build dupeGuru from source
+
+### Prerequisites
+
+* Python 3.4+ compiled in "framework mode".
+* MacOS 10.10+ with XCode command line tools.
+
+### make
+
+You can build the app with `make`:
+
+    $ make
+    $ make run
+
+### pyenv
+
+[pyenv][pyenv] is a popular way to manage multiple python versions. However, be aware that dupeGuru
+will not compile with a pyenv's python unless it's been built with `--enable-framework`. You can do
+this with:
+
+    $ env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install 3.4.3
