 ### Starter kit
 
-Use [vue-cli](https://github.com/vuejs/vue-cli) to create a vant project.
+We recomment to use [Vue Cli 3](https://cli.vuejs.org/zh/) to create a project.
 
-```shell
-vue init youzan/vue-cli-template-vant projectName
+```bash
+# Install Vue Cli
+npm install -g @vue/cli
+
+# Create a project
+vue create hello-world
 ```
 
+After the creation is complete, you can open the GUI by command.
+
+```bash
+# Open GUI
+vue ui
+```
+
+In the GUI, click on 'Dependencies' -> `Install Dependencies` and add `vant` to the dependencies.

 Then you can import components from vant, equivalent to import manually below.
