+## Installation
+
+The easiest way to use Volcano is to use the Helm chart.
+
+
+### 1. Volcano Image
+Official images now are not available on DockerHub, however you can build them locally with command:
+```
+make docker
+``` 
+**NOTE**: You need ensure the images are correctly loaded in your kubernetes cluster, for
+example, if you are using [kind cluster](https://github.com/kubernetes-sigs/kind), 
+try command ```kind load docker-image <image-name>:<tag> ``` for each of the images.
+
+### 2. Helm charts
+First of all, clone repo to your local path
+```
+# mkdir -p $GOPATH/src/volcano.sh/
+# cd $GOPATH/src/volcano.sh/
+# git clone https://github.com/volcano-sh/volcano.git
+```
+Second, install required helm plugin and generate valid certificate, volcano uses a helm plugin **gen-admission-secret**
+to generate certificate for admission service to communicate with kubernetes API server.
+```
+#1. Install helm plugin
+helm plugin install installer/chart/volcano/plugins/gen-admission-secret
+
+#2. Generate secret within service name
+helm gen-admission-secret --service <specified-name>-admission-service --namespace <namespace>
+```
+Finally, install helm chart.
+```
+helm install installer/chart/volcano --namespace <namespace> --name <specified-name>
+```
+**NOTE**:The ```<specified-name>``` used in the two commands above should be identical.
