+## Drag and Drop Tester for macOS
+
+Simple macOS app that allows you to drag and drop anything and inspect the pasteboard types.  It was written using [RubyMotion](http://www.rubymotion.com).
+
+### Installation
+
+A built application can be found in the `bin` folder.  If you have RubyMotion installed, then you can change to the folder and run `rake` from the command line.
+
+### Using the program
+
+After starting the app, drag anything (a webpage image, text, etc) into the drop rectangle.  You will
+then be shown the Pasteboard types for that object.
+
+For example, dragging the address bar link `https://www.apple.com` from Safari will generate
+the following output:
+
+```
+https://www.apple.com/
+   PB type: dyn.ah62d4rv4gu8yc6durvwwa3xmrvw1gkdusm1044pxqyuha2pxsvw0e55bsmwca7d3sbwu
