+#### 可选：使用高可用部署
+
+如果你想要使用高可用部署，需要配置使用certManager托管证书，并开启leader-election和设置 `replicaCount` 大于等于3，例如:
+
+```bash
+$ helm install kruise-game openkruise/kruise-game \
+    --set replicaCount=3 \
+    --set certificates.autoGenerated=false \
+    --set certificates.certManager.enabled=true \
+    --set kruiseGame.leaderElection=true
+```
+
+如果需要升级已有的部署，可以参考使用如下命令:
+
+```bash
+# 使用helm纳管webhook, helm <= v3.16>
+$ kubectl label mutatingwebhookconfiguration kruise-game-mutating-webhook app.kubernetes.io/managed-by=Helm
+$ kubectl annotate mutatingwebhookconfiguration kruise-game-mutating-webhook meta.helm.sh/release-name=kruise-game

+    --set replicaCount=3 \
+    --set certificates.autoGenerated=false \
+    --set certificates.certManager.enabled=true \
+    --set kruiseGame.leaderElection=true
+
+# helm > v3.17, 可直接使用 --take-ownership 参数
+$ helm upgrade kruise-game openkruise/kruise-game --take-ownership \
+    --set replicaCount=3 \

+#### Optional: Use High-Availability Deployment
+
+If you want to use a high-availability deployment, you need to configure cert-manager to manage certificates, enable leader-election, and set `replicaCount` to be greater than or equal to 3. For example:
+
+```bash
+$ helm install kruise-game openkruise/kruise-game \
+    --set replicaCount=3 \
+    --set certificates.autoGenerated=false \
+    --set certificates.certManager.enabled=true \
+    --set kruiseGame.leaderElection=true
+```
+
+To upgrade an existing deployment, you can use the following command:
+
+```bash
+# Manage webhooks with Helm, helm <= v3.16>
+$ kubectl label mutatingwebhookconfiguration kruise-game-mutating-webhook app.kubernetes.io/managed-by=Helm
+$ kubectl annotate mutatingwebhookconfiguration kruise-game-mutating-webhook meta.helm.sh/release-name=kruise-game

+    --set certificates.autoGenerated=false \
