 The software supports multiple configurations of the Arm Corstone™-300 subsystem, incorporating the Cortex-M55 processor and Arm Ethos™-U55 microNPU.  This total solution provides the complex, non differentiated secure platform software on behalf of the ecosystem, thus enabling you to focus on your next killer app.  
 
-This repo also supports a GitHub runner CI/CD workflow right out of the box which leverages [Arm Virtual Hardware](https://www.arm.com/virtual-hardware), a simulation environment that enables software development without the need of physical SoCs.  The source code in this repo supports several configurations of the software, all of which are AWS IoT Core (OTA, etc.) enabled right out of the box. Instructions for using non-default configurations are coming soon!

 ## Keyword detection application  
 
 The keyword detection application runs the DS-CNN model on top of [AWS FreeRTOS](https://docs.aws.amazon.com/freertos/). It detects keywords and inform the user of which keyword has been spotted. The audio data to process are injected at run time using the [Arm Virtual Hardware](https://www.arm.com/virtual-hardware) audio driver. 
 
-The Keyword application connects to [AWS IoT](https://docs.aws.amazon.com/iot/latest/developerguide/what-is-aws-iot.html) cloud to publish recognised keywords.
