+#### Deploy SkyWalking with local files
+
+##### **Package the corresponding version of the skywalking chart**
+
+1.Configure the helm environment, [refer to Helm environment configuration](https://github.com/helm/helm). If you want to deploy the helm2 related chart, you can directly configure the relevant environment of helm2. The following example uses the Helm 3 environment.
+
+2.Clone/download ZIP [**skywalking-kubernetes**](https://github.com/apache/skywalking-kubernetes) repo, the directory structure of the repo about chart is as follows
+
+> helm-chart
+>
+> - helm2
+>   - 6.0.0-GA
+>   - 6.1.0
+> - helm3
+>   - 6.3.0
+>   - 6.4.0
+
+After the clone/download ZIP is completed, enter the specified directory and package the corresponding version of the chart.
+
+```shell
+cd skywalking-kubernetes/helm-chart/<helm-version>/<skywalking-version>
+```
+
+Note: helm-version is the corresponding helm version directory, skywalking-version is the corresponding skywalking version directory, and below is helm3 and skywalking 6.3.0.
+
+```shell
+cd skywalking-kubernetes/helm-chart/helm3/6.3.0
+```
+
+3.Since skywalking relies on elasticsearch as storage, execute the following command to update dependencies, which will be pulled from the official repo by default.
+
+```shell
+helm dep up skywalking
+```
+
+> Hang tight while we grab the latest from your chart repositories...
+> ...Successfully got an update from the "stable" chart repository
+> Update Complete. ⎈Happy Helming!⎈
+> Saving 1 charts
+> Downloading elasticsearch from repo https://kubernetes-charts.storage.googleapis.com/
+> Deleting outdated charts
+
+If the official repo does not exist, please add the official repository first.
+
+```shell
+helm repo add stable https://kubernetes-charts.storage.googleapis.com
+```
+
+> "stable" has been added to your repositories
+
+4.Packing skywalking , execute the following command.
+
+```shell
+helm package skywalking/
+```
+
+> Successfully packaged chart and saved it to: C:\code\innerpeacez_github\skywalking-kubernetes\helm-chart\helm3\6.3.0\skywalking-0.1.0.tgz
+
+After the package is completed, the .tgz file will be generated in the same directory of the current directory.
+
+```
+ ls
+```
+
+> skywalking/  skywalking-0.1.0.tgz
+
+5.Deploy skywalking
+
+```shell
+helm install skywalking skywalking-0.1.0.tgz
+```
