message: [Doc] vue cli 3
diff: ### 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.
  +
  +<img width="100%" style="box-shadow: 0 1px 1px rgba(0, 0, 0, .1); border-radius: 3px;" src="https://img.yzcdn.cn/vant/vue-cli-demo-201809030812.png" >

  +// For users who use babel7, that can be configured in babel.config.js
  +module.exports = {
  + plugins: [
  + ['import', {
  + libraryName: 'vant',
  + libraryDirectory: 'es',
  + style: true
  + }, 'vant']
  + ]
  +};
  ```
  Then you can import components from vant, equivalent to import manually below.
