+> [NOTE]
+> The following values must be set before you can deploy:
+> HUGGINGFACEHUB_API_TOKEN
+
+> You can also customize the "MODEL_ID" if needed.
+
+> You need to make sure you have created the directory `/mnt/opea-models` to save the cached model on the node where the ChatQnA workload is running. Otherwise, you need to modify the `chatqna.yaml` file to change the `model-volume` to a directory that exists on the node.

+## Deploy On Xeon
+
+```
+cd GenAIExamples/ChatQnA/kubernetes/manifests/xeon
+export HUGGINGFACEHUB_API_TOKEN="YourOwnToken"
+sed -i "s/insert-your-huggingface-token-here/${HUGGINGFACEHUB_API_TOKEN}/g" chatqna.yaml
+kubectl apply -f chatqna.yaml
+```
+
+## Deploy On Gaudi
+
+```
+cd GenAIExamples/ChatQnA/kubernetes/manifests/gaudi
+export HUGGINGFACEHUB_API_TOKEN="YourOwnToken"
+sed -i "s/insert-your-huggingface-token-here/${HUGGINGFACEHUB_API_TOKEN}/g" chatqna.yaml
+kubectl apply -f chatqna.yaml
+```
+
+## Verify Services
+
+To verify the installation, run the command `kubectl get pod` to make sure all pods are running.
+
+Then run the command `kubectl port-forward svc/chatqna 8888:8888` to expose the ChatQnA service for access.
+
+Open another terminal and run the following command to verify the service if working:
+
+```console
+curl http://localhost:8888/v1/chatqna \
+    -H 'Content-Type: application/json' \
+    -d '{"messages": "What is the revenue of Nike in 2023?"}'
+```
