 title: Offline Installation
 ---
 
-TODO
+If your cluster does not have direct access to the external network, you can use offline deployment to install HAMi
+
+## Prepare your images
+
+You need to save the following images into a tarball and copy it into the cluster.
+Image list:
+```
+projecthami/hami:{HAMi version} 
+docker.io/jettech/kube-webhook-certgen:v1.5.2
+liangjw/kube-webhook-certgen:v1.1.1
+registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler:{your kubernetes version}
+```
+
+Load these images, tag these images with your inner registry, and push them into your registry
+
+```
+docker load -i {HAMi_image}.tar
+docker tag projecthami/hami:{HAMi version} {your_inner_registry}/hami:{HAMi version} 
+docker push {your_inner_registry}/hami:{HAMi version}
+docker tag docker.io/jettech/kube-webhook-certgen:v1.5.2 {your inner_regisry}/kube-webhook-certgen:v1.5.2
+docker push {your inner_regisry}/kube-webhook-certgen:v1.5.2
+docker tag liangjw/kube-webhook-certgen:v1.1.1 {your_inner_registry}/kube-webhook-certgen:v1.1.1
+docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler:{your kubernetes version} {your_inner_registry}/kube-scheduler:{your kubernetes version}
+docker push {your_inner_registry}/kube-scheduler:{your kubernetes version}  
+```
+
+## Prepare HAMi chart
+
+Download the charts folder from [github](https://github.com/Project-HAMi/HAMi/tree/master/charts), place it into ${CHART_PATH} inside cluser, then edit the following fields in ${CHART_PATH}/hami/values.yaml. 
+
+```
+scheduler.kubeScheduler.image
+scheduler.extender.image
+scheduler.patch.image
+scheduler.patch.imageNew
+scheduler.devicePlugin.image
+scheduler.devicePlugin.monitorimage
+```
+
+## Execute the following command in your ${CHART_PATH} folder
+
+```
+helm install hami hami --set scheduler.kubeScheduler.imageTag={your k8s server version} -n kube-system
+```
+
+7. Verify your installation
+
+execute the following command
+```
+kubectl get pods -n kube-system
+```
+
+If you can see both the 'device-plugin' and 'schduler' running, then HAMi is installed successfully,
