 [vLLM](https://docs.vllm.ai/en/stable/) is a fast and user-friendly library for LLM inference and serving.
 
 vLLM offers an `OpenAI Compatible Server`, enabling us to use the OpenAI kinds for chat and embedding.
-However, for completion, there are certain differences in the implementation. Therefore, we should use the `vllm/completion` kind and provide a `prompt_template` depending on the specific models.

-Below is an example
+Please note that models differ in their capabilities for completion or chat.
+You should confirm the model's capability before employing it for chat or completion tasks.
+
+Additionally, there are models that can serve both as chat and completion.
+For detailed information, please refer to the [Model Registry](../../models/index.mdx).
+
+Below is an example of the vLLM running at `http://localhost:8000`:
+
+Please note the following requirements in each model type:
+1. `model_name` must exactly match the one used to run vLLM.
+2. `api_endpoint` should follow the format `http://host:port/v1`.
+3. `api_key` should be identical to the one used to run vLLM.
