 IPVS runs on a host and acts as a load balancer in front of a cluster of real servers. IPVS can direct requests for TCP
 and UDP-based services to the real servers, and make services of real servers appear as virtual services on a single IP address.
 
-## How to use
+## Run kube-proxy in ipvs mode
 
-#### Load IPVS kernel modules
+Currently, local-up scripts and kubeadm support switching IPVS proxy mode via exporting environment variables or specifying flags.
 
-Currently the IPVS kernel module can't be loaded automatically, so first we should use the following command to load IPVS kernel
-modules manually.
-
-```shell
-modprobe ip_vs
-modprobe ip_vs_rr
-modprobe ip_vs_wrr
-modprobe ip_vs_sh
-modprobe nf_conntrack_ipv4
-```
-
-After that, use `lsmod | grep ip_vs` to make sure kernel modules are loaded.

+### Local UP Cluster
 
 Kube-proxy will run in iptables mode by default in a [local-up cluster](https://github.com/kubernetes/community/blob/master/contributors/devel/running-locally.md). 
 
 Users should export the env `KUBEPROXY_MODE=ipvs` to specify the ipvs mode before deploying the cluster if want to run kube-proxy in ipvs mode.

+### Why kube-proxy can't start IPVS mode
+
+People can do the following check list step by step:
+
+**1. Enable IPVS feature gateway**
+
+Currently IPVS-based kube-proxy is still in alpha phase, people need to enable `--feature-gates=SupportIPVSProxyMode=true` explicitly.
+
+**2. Specify proxy-mode=ipvs**
+
+Tell kube-proxy that proxy-mode=ipvs, please.

+**3. Load ipvs required kernel modules**

+The following kernel modules are required by IPVS-based kube-proxy:

+```shell

+ip_vs_wrr
+ip_vs_sh
+nf_conntrack_ipv4

+IPVS-based kube-proxy will load them automatically. If it fails to load them, please check whether they are compiled into your kernel.
