+# Build Mega Service of ChatQnA on Xeon
+
+Quick Start:
+
+1. Set up the environment variables.
+2. Run Docker Compose.
+3. Consume the ChatQnA Service.
+
+## Quick Start: 1.Setup Environment Variable
+
+```bash
+mkdir ~/OPEA -p
+mkdir ~/OPEA/tmp -p
+cd ~/OPEA
+git clone https://github.com/opea-project/GenAIExamples.git
+# If you want to build code, download GenAIComps
+git clone https://github.com/opea-project/GenAIComps.git
+```
+
+To set up environment variables for deploying ChatQnA services, follow these steps:
+
+1. Set the required environment variables:
+
+   ```bash
+   # Example: host_ip="192.168.1.1"
+   export host_ip="External_Public_IP"
+   export HUGGINGFACEHUB_API_TOKEN="Your_Huggingface_API_Token"
+   ```
+
+2. If you are in a proxy environment, also set the proxy-related environment variables:
+
+   ```bash
+   export http_proxy="Your_HTTP_Proxy"
+   export https_proxy="Your_HTTPs_Proxy"
+   # Example: no_proxy="localhost, 127.0.0.1, 192.168.1.1"
+   # Example: no_proxy="localhost, 127.0.0.1, 192.168.1.1"
+   ```
+
+3. Set up other environment variables:
+   ```bash
+   export host_ip="External_Public_IP"
+   export HUGGINGFACEHUB_API_TOKEN="Your_Huggingface_API_Token"
+   source ./set_env_milvus.sh
+   ```
+
+## Quick Start: 2.Run Docker Compose
+
+```bash
+cd ~/OPEA/GenAIExample/ChatQnA/docker_compose/intel/cpu/xeon
+docker compose -f ./compose_milvus.yaml up -d
+```
+
+It will automatically download the docker images on `docker hub`.
+
+In following cases, you could build docker image from source by yourself.
+
+- Failed to download the docker image.
+
+- If you want to use a specific version of Docker image.
+
+Please refer to 'Build Docker Images' in below.
+
+## QuickStart: 3.Consume the ChatQnA Service
+
+```bash
+curl http://${host_ip}:8888/v1/chatqna \
+    -H "Content-Type: application/json" \
+    -d '{
+        "messages": "What is the revenue of Nike in 2023?"
+    }'
+```
+
+## 🚀 Build Docker Images
+
+First of all, you need to build Docker Images locally and install the python package of it.
+
+```bash
+cd ~/OPEA/GenAIExample/ChatQnA/docker_compose/intel/cpu/xeon
+docker compose -f ./compose_milvus.yaml build
+```
+
+Then run the command `docker images`, you will have the following 5 Docker Images:
+
+1. `opea/dataprep-milvus:latest`
+2. `opea/retriever-milvus:latest`
+3. `opea/chatqna:latest`
+4. `opea/chatqna-ui:latest`
+5. `opea/nginx:latest`
+
+## 🚀 Start Microservices
+
+```
+cd ~/OPEA/GenAIExample/ChatQnA/docker_compose/intel/cpu/xeon
+docker compose -f up -d
+```
+
+### Valid the Microservices and Launch the UI
+
+To valid the Microservices, change models as well as Launch the UI, Pleser refer to ./README.md
