 # NVIDIA GPU Driver Extension for Linux
 
 This extension installs NVIDIA GPU drivers on Linux N-series virtual machines (VMs). Depending on the VM family, the extension installs CUDA or GRID drivers. When you install NVIDIA drivers by using this extension, you're accepting and agreeing to the terms of the [NVIDIA End-User License Agreement](https://www.nvidia.com/en-us/data-center/products/nvidia-ai-enterprise/eula/). During the installation process, the VM might reboot to complete the driver setup.
 
-Instructions on manual installation of the drivers and the current supported versions are available. For more information, see [Azure N-series GPU driver setup for Linux](../linux/n-series-driver-setup.md).
