 Because Kinect programming is a pain in the neck, and by trivializing the device's output into a simple text format, it becomes infinitely easier to digest in the scripting language of your choice.
 
+### This seems simple to the point of being almost useless
+
+Yes, that's the point. Do One Thing and Do It Well. There's an accompanying rubygem that will add all the smart stuff like advanced gesture recognition, events, etc.
+
 ## USAGE
 
-    % kinectable_pipe -r 30
+    % kinectable_pipe | ruby some_other_script.rb
+
+## INSTALLATION (OS X / homebrew)
+
+    # must have universal binary for libusb
+    brew uninstall libusb
+    brew install libusb --universal
+
+    brew tap marshally/alt
+
+    brew install kinectable_pipe
+
+    # now plug in your kinect
+    # and run this command in the terminal
+
+    kinectable_pipe
+
+    # step back from the sensor, wave your arms like a lunatic
+    # until it recognizes you and starts pumping out skeleton data
+    # to STDOUT
+
+## TODO
+
+1. Recognize all available `xn::GestureGenerator`
+1. Fix output to work with non-interactive terminal sessions.
+1. Add CLI argument `-r` to change output framerate.
+1. Improve Ruby sample app.
+1. Add sample apps for other scripting languages.
+1. Add CLI argument for alternate output encodings (XML, msgpack, BERT, whatever).
