+description: My first hello world helm chart.
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+version: 0.1.1
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application.

+## 功能介绍 *(此处介绍charts功能)*
+
+展示一个web页面，可以根据values值改变页面的输出内容。
+
+
+
+## 安装使用 *(此处介绍安装方式)*
+
+```shell
+helm install my-hello-world-test1 my-hello-world
+```
+
+运行后看到输出：
+
+```shell
+NAME: my-hell-world
+LAST DEPLOYED: 2019-07-16 10:30:41.927128 +0800 CST m=+0.132308108
+NAMESPACE: default
+STATUS: deployed
+
+NOTES:
+1. Get the application URL by running these commands:
+  export POD_NAME=$(kubectl get pods -l "app.kubernetes.io/name=my-hello-world,app.kubernetes.io/instance=my-hell-world" -o jsonpath="{.items[0].metadata.name}")
+  echo "Visit http://127.0.0.1:8080 to use your application"
+  kubectl port-forward $POD_NAME 8080:80
+```
+
+执行完 NOTES 中提示命令的命令即可在浏览器中访问 `http://127.0.0.1:8080` 查看。
+
+## 使用参数 *(此处介绍进阶功能)*
+
+```shell
+helm install my-hello-world-chart-test2 my-hello-world --set Username="Cloud Native"
+```
+
+同样按输出的 NOTES 执行后看到的页面输出会有变化。
+
