 - Start the HugeGraph database, you can do it via Docker. Refer to [docker-link](https://hub.docker.com/r/hugegraph/hugegraph) & [deploy-doc](https://hugegraph.apache.org/docs/quickstart/hugegraph-server/#31-use-docker-container-convenient-for-testdev) for guidance
 - Start the gradio interactive demo, you can start with the following command, and open http://127.0.0.1:8001 after starting
     ```bash
-    # ${PROJECT_ROOT_DIR} is the root directory of hugegraph-ai, which needs to be configured by yourself
+    # 0. clone the hugegraph-ai project & enter the root dir

-- Configure HugeGraph database connection information and LLM information, which can be configured in two ways:
-  1. Configure the `./hugegraph-llm/src/config/config.ini` file
-  2. In gradio, after completing the configurations for LLM and HugeGraph, click on `Initialize configs`, the complete and initialized configuration file will be outputted.
+- Configure HugeGraph database connection information & LLM information in the gradio interface,
