+The NVIDIA operator cannot automatically install kernel drivers on SLES. NVIDIA drivers must be manually installed on all GPU nodes before deploying the operator in the cluster.
 
+The SLES repositories have the nvidia-open packages, which include the open gpu kernel drivers. If your GPU supports the open drivers, you can check that in this [list](https://github.com/NVIDIA/open-gpu-kernel-modules#compatible-gpus), you can install the drivers by executing:
 ```
-# Assuming you are using sle15sp5, if different, change the url accordingly
-sudo zypper addrepo --refresh 'https://download.nvidia.com/suse/sle15sp5' NVIDIA
+sudo zypper install -y nvidia-open

+If the GPU does not support gpu kernel drivers, you will need to download the proprietary drivers from an NVIDIA repo. In that case, follow these steps:

 The NVIDIA operator can automatically install kernel drivers on Ubuntu using the `nvidia-driver-daemonset`, although not all versions are supported. You can also pre-install them manually and the operator will detect them: 
 
 ```
-sudo apt install nvidia-driver-535-server
+sudo apt install nvidia-driver-550-server
 ```
 Then reboot.
