-### Set Custom Prompt Templates
+### Quick Start - Config 
 
-LiteLLM by default checks if a model has a [prompt template and applies it](./completion/prompt_formatting.md) (e.g. if a huggingface model has a saved chat template in it's tokenizer_config.json). However, you can also set a custom prompt template on your proxy in the `config.yaml`: 
-
-**Step 1**: Save your prompt template in a `config.yaml`
-```yaml
-# Model-specific parameters
-model_list:
-  - model_name: mistral-7b # model alias
-    litellm_params: # actual params for litellm.completion()

-### Using Multiple Models 
-
-If you have 1 model running on a local GPU and another that's hosted (e.g. on Runpod), you can call both via the same litellm server by listing them in your `config.yaml`. 
+Here's how you can use multiple llms with one proxy `config.yaml`. 
 
+#### Step 1: Setup Config
 ```yaml
 model_list:
   - model_name: zephyr-alpha
     litellm_params: # params for litellm.completion() - https://docs.litellm.ai/docs/completion/input#input---request-body

       api_base: http://0.0.0.0:8001
-  - model_name: zephyr-beta
+  - model_name: gpt-4
     litellm_params:
-      model: huggingface/HuggingFaceH4/zephyr-7b-beta
-      api_base: https://<my-hosted-endpoint>
+      model: gpt-4
+      api_key: sk-1233

 ```shell
 $ litellm --config /path/to/config.yaml

 If you're repo let's you set model name, you can call the specific model by just passing in that model's name -
