+kinect-audio-setup makes audio input from the Microsoft Kinect Sensor
+device work on GNU/Linux systems.
+
+When the Kinect is first plugged in the USB port it shows up as
+a generic USB device with a bulk endpoint; after uploading a certain
+firmware a reenumeration takes place and a USB Audio Class (UAC) device
+becomes available.
+
+kinect-audio-setup provides tools to download the firmware off the net
+at installation time —since the firmware is not redistributable—, and it
+sets up udev rules to call the firmware loader when the device is
+plugged in to finally get the USB Audio Class device.
+
+Note that for all the magic to happen automatically pulseaudio >= 1.0 is
+needed, as it contains the kinect-audio.conf profile which fixes audio
+device detection:

+
+kinect-audio-setup provides:
+  - kinect_fetch_fw which downloads and extracts the firmware from the
+    Microsoft Kinect SDK;
+  - kinect_upload_fw which loads the firmware to the generic USB device
+    in order to get the USB Audio Class device to show up;
+  - udev rules to call kinect_upload_fw when the device is plugged in.
+
+
+To install kinect-audio-setup from the source distribution follow the
+steps below with superuser rights:
+
 Install kinect_upload_fw first:
 
-  $ make install
+  # make install
+
+it will be copied to /usr/local/sbin by default, assign the PREFIX
+variable on the command line to install it to another location.
+
+Then install the udev rules to automate the firmware loading:
+
+  # make install_udev_rules \
+    FIRMWARE_PATH=/lib/firmware/kinect/UACFirmware
+    LOADER_PATH=/usr/local/sbin/kinect_upload_fw
+
+Then run the firmware fetcher script (remember this is only needed
+once):
+
+  # ./kinect_fetch_fw /lib/firmware/kinect
+  # udevadm control --reload-rules
+
+
+The UAC firmware is downloaded from the Microsoft Kinect SDK at
+http://www.kinectforwindows.org, the license of the SDK can be found at
+http://research.microsoft.com/en-us/um/legal/kinectsdk-tou_noncommercial.htm
 
-Then run the firmware download script:

-  $ ./kinect_fetch_fw /lib/firmware/kinect
+A special thanks goes to Steven Toth from http://kernellabs.com, who
+kindly sponsored a Kinect to Antonio Ospite and made kinect-audio-setup
+possible in its current form.
