+a light package to simplify calling OpenAI, Azure, Cohere, Anthropic, Huggingface API Endpoints. It manages:
+- translating inputs to the provider's completion and embedding endpoints
+- guarantees [consistent output](https://litellm.readthedocs.io/en/latest/output/), text responses will always be available at `['choices'][0]['message']['content']`
+- exception mapping - common exceptions across providers are mapped to the [OpenAI exception types](https://help.openai.com/en/articles/6897213-openai-library-error-types-guidance)

 ## Streaming Queries
 liteLLM supports streaming the model response back, pass `stream=True` to get a streaming iterator in response.
+Streaming is supported for OpenAI, Azure, Anthropic models
 ```python
 response = completion(model="gpt-3.5-turbo", messages=messages, stream=True)
 for chunk in response:
    print(chunk['choices'][0]['delta'])
+
+# claude 2
+result = completion('claude-2', messages, stream=True)

+
+All [`text2text-generation`](https://huggingface.co/models?library=transformers&pipeline_tag=text2text-generation&sort=downloads) and [`text-generation`](https://huggingface.co/models?library=transformers&pipeline_tag=text-generation&sort=downloads) models are supported by liteLLM. You can use any text model from Hugging Face with the following steps:
+
+* Copy the `model repo` URL from Hugging Face and set it as the `model` parameter in the completion call.
+* Set `hugging_face` parameter to `True`.
+* Make sure to set the hugging face API key
+
+Here are some examples of supported models:
+**Note that the models mentioned in the table are examples, and you can use any text model available on Hugging Face by following the steps above.**

+# Token Usage
+By default LiteLLM returns token usage in all completion requests ([See here](https://litellm.readthedocs.io/en/latest/output/))
+
+However, we also expose 3 public helper functions to calculate token usage across providers:
+
+- `token_counter`: This returns the number of tokens for a given input - it uses the tokenizer based on the model, and defaults to tiktoken if no model-specific tokenizer is available. 
+
+- `cost_per_token`: This returns the cost (in USD) for prompt (input) and completion (output) tokens. It utilizes our model_cost map which can be found in `__init__.py` and also as a [community resource](https://github.com/BerriAI/litellm/blob/main/cookbook/community-resources/max_tokens.json).
+
+- `completion_cost`: This returns the overall cost (in USD) for a given LLM API Call. It combines `token_counter` and `cost_per_token` to return the cost for that query (counting both cost of input and output). 
+
+## Example Usage 
+
+1. `token_counter`
+
+```python
+from litellm import token_counter
+
+messages = [{"user": "role", "content": "Hey, how's it going"}]
+print(token_counter(model="gpt-3.5-turbo", messages=messages))
+```
+
+2. `cost_per_token`
+
+```python
+from litellm import cost_per_token
+
+prompt_tokens =  5
+completion_tokens = 10
