 ### 2. How can I change the default model after it has been run once?
-1. Delete the existing model located in `./data/ov_model`.
+1. Delete the volume for the container.
 ```bash
-rm -rf ./data/ov_model
+docker volume rm ov-vllm
 ```
 2. Rerun the `docker run` command to load and quantize the new model.
