 ## Hugging Face Runtime Arguments
 
-Below, you can find an explanation of command line arguments which are supported for Hugging Face runtime. [vLLM backend engine arguments](https://docs.vllm.ai/en/latest/models/engine_args.html) can also be specified on the command line argument which is parsed by the Hugging Face runtime.

 - `--model_name`: The name of the model used on the endpoint path.
 - `--model_dir`: The local path where the model is downloaded to. If `model_id` is provided, this argument will be ignored.
-- `--model_id`: Huggingface model id.
-- `--model_revision`: Huggingface model revision.
-- `--tokenizer_revision`: Huggingface tokenizer revision.
+- `--model_id`: Hugging Face model id.
+- `--model_revision`: Hugging Face model revision.
+- `--tokenizer_revision`: Hugging Face tokenizer revision.
 - `--dtype`: Data type to load the weights in. One of 'auto', 'float16', 'float32', 'bfloat16', 'float', 'half'. 
              Defaults to float16 for GPU and float32 for CPU systems. 'auto' uses float16 if GPU is available and uses float32 otherwise to ensure consistency between vLLM and HuggingFace backends. 
              Encoder models defaults to 'float32'. 'float' is shorthand for 'float32'. 'half' is 'float16'. The rest are as the name reads.
