 ### Linux
-To running on Intel GPU, there are two prerequisites: Intel GPU dervier and [Intel® oneAPI Base Toolkit 2024.0](https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html) installation. For more details, please refer to [this installation guide](https://bigdl.readthedocs.io/en/latest/doc/LLM/Overview/install_gpu.html#id1).
+For Linux system, we recommend Ubuntu 20.04 or later (Ubuntu 22.04 is preferred).

 ### Model Download
 Before running, you should download or copy community GGUF model to your current directory. For instance,  `mistral-7b-instruct-v0.1.Q4_K_M.gguf` of [Mistral-7B-Instruct-v0.1-GGUF](https://huggingface.co/TheBloke/Mistral-7B-Instruct-v0.1-GGUF/tree/main).
 
 ### Run the quantized model
 
-```cmd
-./main -m mistral-7b-instruct-v0.1.Q4_K_M.gguf -n 32 --prompt "Once upon a time, there existed a little girl who liked to have adventures. She wanted to go to places and meet new people, and have fun" -t 8 -e -ngl 33 --color
