 If you are familiar with the helm chart installation, please refer to [KubeEdge Helm Charts](https://github.com/kubeedge/kubeedge/tree/master/manifests/charts).
 
 
+**SPECIAL SCENARIO:**
+In the case of insufficient qualifications for edge nodes, we need to label them to prevent some applications from extending to edge nodes.

+
+Any daemonset cannot occupy the hardware resources of edge nodes.

 ### keadm manifest generate
 
 You can also get the manifests with `keadm manifest generate`.

 当您看到以上信息，说明 KubeEdge 的云端组件 cloudcore 已经成功运行。
 
+**特殊场景：** 
+边缘计算的硬件条件不好的情况，这里我们需要打上标签，让一些应用不扩展到edge节点上去。

 ### keadm beta init
 
 如果您想要使用容器化方式部署云端组件 cloudcore ，您可以使用 `keadm beta init` 进行云端组件安装。
