 ## AVS SDK installation and Raspberry Pi audio setup
 
 1. Open a terminal window on the Raspberry Pi desktop and clone the vocalfusion-avs-setup repository:
 
    ```git clone https://github.com/xmos/vocalfusion-avs-setup```
+
+   **DO NOT** use the command 'apt update' to update the software database. This will cause the installation to fail. **DO NOT** update the kernel, as this will cause the audio sub-sytem to fail.
 
 2. Register an AVS product, create a security profile and save a *config.json* file by following https://developer.amazon.com/en-US/docs/alexa/alexa-voice-service/register-a-product.html. It is strongly recommended that the config.json file should be saved onto a USB memory stick for future use.
