vllm and arc a770 instructions needed

Hello.
I want to use the latest vllm with 4x A770. 
What steps should i do? 

Do i need to use
``` https://github.com/jikunshang/vllm ```
or all i need is implemented to vllm main? 

Ipex-llm support is ended, and i don't know where and how to start with the latest vllm now.. 
The Llm-scaller project is for bmg (b580/b60)
