+This repository contains scripts for running large language models using text generation inference APIs and (chat) UIs.
 
 ## Authentication
 Certain models (e.g., Google-gemma, LLAMA3, etc.) require you to accept the license on the Hugging Face website. To download these models to your machine, you need an authentication token from [Hugging Face](https://huggingface.co/settings/tokens). To register your token on your machine, run the following command:
 
 ```sh
 huggingface-cli login --token <yourToken>
 ```
+For proper functionality, ensure the script has access to your API key, typically located at `$HOME/.cache/huggingface`. Use the following snippet to mount this directory in your srun command:
+
+```sh
+$HOME/.cache/huggingface:/root/.cache/huggingface
+```
