+Snowboy now brings hands-free experience to the [Alexa AVS sample app](https://github.com/alexa/avs-device-sdk/wiki/Raspberry-Pi-Quick-Start-Guide-with-Script) on Raspberry Pi! See more info below regarding the performance and how you can use other hotword models. The following instructions currently support AVS sdk Version 1.12.1.
 
 **Performance**
 
 The performance of hotword detection usually depends on the actual environment, e.g., is it used with a quality microphone, is it used on the street, in a kitchen, or is there any background noise, etc. So we feel it is best for the users to evaluate it in their real environment. For the evaluation purpose, we have prepared an Android app which can be installed and run out of box: [SnowboyAlexaDemo.apk](https://github.com/Kitt-AI/snowboy/raw/master/resources/alexa/SnowboyAlexaDemo.apk) (please uninstall any previous versions first if you have installed this app before). 
 
+**Kittai KWD Engine**
+
+* Set up [Alexa AVS sample app](https://github.com/alexa/avs-device-sdk/wiki/Raspberry-Pi-Quick-Start-Guide-with-Script) following the official AVS instructions
+
+* Apply patch to replace the Sensory KWD engine with Kittai engine
+```
+# Copy the patch file to the root directory of Alexa AVS sample app. Please replace $ALEXA_AVS_SAMPLE_APP_PATH with the actual path where you
+# cloned the Alexa AVS sample app repository, and replace $SNOWBOY_ROOT_PATH with the actual path where you clone the Snowboy repository
+cd $ALEXA_AVS_SAMPLE_APP_PATH
+cp $SNOWBOY_PATH/resource/alexa/alexa-avs-sample-app/avs-kittai.patch ./
+
+# Apply the patch, this will modify the scripts setup.sh and pi.sh
+patch < avs-kittai.patch
+```
+
+* Re-compile the avs-device-sdk and sample app
+```
+sudo bash setup.sh config.json
+```
+
+* Run the sample app
+```
+sudo bash startsample.sh
+```
+
+Here is a [demo video](https://www.youtube.com/watch?v=wiLEr6TeE58) for how to use Snowboy hotword engine in Alexa Voice Service.
+
 **Personal model**
 
 * Create your personal hotword model through our [website](https://snowboy.kitt.ai) or [hotword API](https://snowboy.kitt.ai/api/v1/train/)
 
-* Replace the hotword model in [Alexa AVS sample app](https://github.com/alexa/alexa-avs-sample-app) (after installation) with your personal model
 
+* Put your personal model in [snowboy/resources](https://github.com/Kitt-AI/snowboy/tree/master/resources)
 ```
-# Please replace YOUR_PERSONAL_MODEL.pmdl with the personal model you just
-# created, and $ALEXA_AVS_SAMPLE_APP_PATH with the actual path where you
-# cloned the Alexa AVS sample app repository.
-cp YOUR_PERSONAL_MODEL.pmdl $ALEXA_AVS_SAMPLE_APP_PATH/samples/wakeWordAgent/ext/resources/alexa.umdl
-```
+# Please put YOUR_PERSONAL_MODEL.pmdl in $ALEXA_AVS_SAMPLE_APP_PATH/third-party/snowboy/resources,
+# and $ALEXA_AVS_SAMPLE_APP_PATH with the actual path where you put the Alexa AVS sample app repository.
+
+cp YOUR_PERSONAL_MODEL.pmdl $ALEXA_AVS_SAMPLE_APP_PATH/third-party/snowboy/resources/
 
-* Set `APPLY_FRONTEND` to `false` and update `SENSITIVITY` in the [Alexa AVS sample app code](https://github.com/alexa/alexa-avs-sample-app/blob/master/samples/wakeWordAgent/src/KittAiSnowboyWakeWordEngine.cpp) and re-compile
+```
 
+* Replace the model name 'alexa.umdl' with your personal model name, update `KITT_AI_SENSITIVITY`, set `KITT_AI_APPLY_FRONT_END_PROCESSING` to `false` in the [Alexa AVS sample app code](https://github.com/alexa/avs-device-sdk/blob/master/KWD/KWDProvider/src/KeywordDetectorProvider.cpp) and re-compile
 ```

-# cloned the Alexa AVS sample app repository.
-cd $ALEXA_AVS_SAMPLE_APP_PATH/samples/wakeWordAgent/src/
-
-# Modify KittAiSnowboyWakeWordEngine.cpp and update SENSITIVITY at line 28.
-# Modify KittAiSnowboyWakeWordEngine.cpp and set APPLY_FRONTEND to false at
-# line 30.
-make

 ```
 
 * Run the wake word agent with engine set to `kitt_ai`!
 
-**Universal model**
+Here is a [demo video](https://www.youtube.com/watch?v=9Bj8kdfwG7I) for how to use a personal model in Alexa Voice Service.
 
-* Replace the hotword model in [Alexa AVS sample app](https://github.com/alexa/alexa-avs-sample-app) (after installation) with your universal model
