+### Prepare configuration file

+All configs are defined in `ColossalQA/examples/webui_demo/config.py`. You can primarily modify the **bolded** sections in the config to switch the embedding model and the large model loaded by the backend. Other parameters can be left as default or adjusted based on your specific requirements.
