 chat.py can be used to initiate a conversation with a specified model. The file is under directory '/root'.
 
-To run chat.py:
+You can download models and bind the model directory from host machine to container when start a container.
+
+Here is an example:
+```bash
+export DOCKER_IMAGE=intelanalytics/bigdl-llm-cpu:2.4.0-SNAPSHOT
+export MODEL_PATH=/home/llm/models
+
+sudo docker run -itd \
+        --net=host \
+        --cpuset-cpus="0-47" \
+        --cpuset-mems="0" \
+        --memory="32G" \
+        --name=CONTAINER_NAME \
+        --shm-size="16g" \
+        -v $MODEL_PATH:/llm/models/
+        $DOCKER_IMAGE
+
 ```
+
+After entering the container through `docker exec`, you can run chat.py by:
+```bash
 cd /root
 python chat.py --model-path YOUR_MODEL_PATH
 ```
+In the example above, it can be:
+```bash
+cd /root
+python chat.py --model-path /llm/models/MODEL_NAME
+```
