+### Additional Steps for Remote Endpoints with Authentication (If No Authentication Skip This Step)
+
+If your remote inference endpoint is protected with OAuth Client Credentials authentication, update CLIENTID, CLIENT_SECRET and TOKEN_URL with the correct values in "chatqna-llm-uservice-config" ConfigMap
+
+
+
+### Deploy
+```
+kubectl apply -f chatqna-remote-inference.yaml
