+# Description:
+#   Control your Philips Hue Lights from HUBOT! BAM, easy candy for the kids
+#
+# Dependencies:
+#
+# Configuration:
+# This script is dependent on environment variables:
+#   PHILIPS_HUE_HASH : export PHILIPS_HUE_HASH="secrets"
+#   PHILIPS_HUE_IP : export PHILIPS_HUE_IP="xxx.xxx.xxx.xxx"
+#
+# Setting your Hue Hash
+# 
+# This needs to be done once, it seems older versions of the Hue bridge used an md5 hash as a 'username' but now you can use anything.
+# 
+# Make an HTTP POST request of the following to http://YourHueHub/api
+# 
+# {"username": "YourHash", "devicetype": "YourAppName"}
+# If you have not pressed the button on the Hue Hub you will receive an error like this;
+# 
+# {"error":{"type":101,"address":"/","description":"link button not pressed"}}
+# Press the link button on the hub and try again and you should receive;
+# 
+# {"success":{"username":"YourHash"}}
+# The key above will be the username you sent, remember this, you'll need it in all future requests
+#
+# ie: curl -v -H "Content-Type: application/json" -X POST 'http://YourHueHub/api' -d '{"username": "YourHash", "devicetype": "YourAppName"}'
+#
+#
+# Commands:
+#   hue lights - list all lights
+#   hue light <light number>  - shows light status
+#   hue turn light <light number> <on|off> - flips the switch
+#   hue groups - groups lights together to control with one API call
+#   hue config - reads bridge config
+#   hue hash - get a hash code (press the link button)
+#   hue set config (name|linkbutton) <value>- change the name or programatically press the link button
+#   hue (alert|alerts) light <light number> - blink once or blink for 10 seconds specific light
