 ## Create OpenYurt cluster
-`yurtctl init` will create an OpenYurt cluster, but the user needs to install the runtime in advance and ensure that the swap partition of the node has been closed.
+`yurtctl init` will create an OpenYurt cluster, and the user doesn't need to do pre-work, such as install the runtime in advance or ensure that the swap partition of the node has been closed.
 
 Using `yurtctl` to create an OpenYurt cluster can be done by doing the following:
 ```
-$ _output/bin/yurtctl init --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers --kubernetes-version=v1.18.8  --pod-network-cidr=10.244.0.0/16

 ```
-In addition, the OpenYurt components version can be set by the option `--yurt-version`,
-and the OpenYurt components image registry can be set by the option `--yurt-image-registry`.
+The `--apiserver-advertise-address` is the IP address of master, `--passwd` is ssh password of master, `--openyurt-version` is the the OpenYurt cluster version.
+In addition, and the OpenYurt cluster image registry can be set by the option `--image-registry`. If user want to get more help, please use `yurtctl init -h`.
