+
+Helm chart for deploying chathistory-usvc microservice.
+
+chathistory-usvc will use redis and tei service, please specify the endpoints.
+
+## (Option1): Installing the chart separately
+
+First, you need to install the mongodb chart, please refer to the [mongodb](../mongodb) for more information.
+
+After you've deployted the mongodb chart successfully, run `kubectl get svc` to get the service endpoint and URL respectively, i.e. `mongodb:27017`.
+
+To install chathistory-usvc chart, run the following:
+
+```console
+cd GenAIInfra/helm-charts/common/chathistory-usvc
+export MONGO_HOST="mongodb"
+export MONGO_PORT="27017"
+helm dependency update
+helm install chathistory-usvc . --set MONGO_HOST=${MONGO_HOST} --set MONGO_PORT=${MONGO_PORT}
+```
+
+## (Option2): Installing the chart with dependencies automatically
+
+```console
+cd GenAIInfra/helm-charts/common/chathistory-usvc
+helm dependency update
+helm install chathistory-usvc . --set autodependency.enabled=true
+```
+
+## Verify
+
+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/chathistory-usvc 6012:6012` to expose the chathistory-usvc service for access.
+
+Open another terminal and run the following command to verify the service if working:
+
+```console
+curl -X 'POST' \
+  http://localhost:6012/v1/chathistory/create \
+  -H 'accept: application/json' \
+  -H 'Content-Type: application/json' \
+  -d '{"data": {"messages": "test Messages", "user": "test"}}'
+```
+
