<summary>How do `render-content` of Tree and `render-header` of Table work?</summary>
Please refer to [Render Function](http://vuejs.org/v2/guide/render-function.html) in Vue's documentation. In addition, if you are writing render functions with JSX, `babel-plugin-transform-vue-jsx` is required. See [here](https://github.com/vuejs/babel-plugin-transform-vue-jsx) for its configurations.

<summary>When do you update documentations of Element?</summary>
We update documentations only when a new version of Element is published so that it reflects all the changes introduced in that version. Updated changed can be found in the [changelog](https://github.com/ElemeFE/element/blob/master/CHANGELOG.en-US.md)。

<summary>I imported Element in my project, but why does it report CSS error/font file error/components have no style?</summary>
Please refer to our [starter kit](https://github.com/ElementUI/element-starter) and correctly configure file-loader, css-loader and style-loader in webpack config file. Besides, we also provide templated based on [cooking](https://github.com/ElementUI/element-cooking-starter) and [laravel](https://github.com/ElementUI/element-in-laravel-starter).

<summary>I cloned Element's repo, but failed to run it. How do I solve it?</summary>
First, please make sure to clone the latest code in master branch and cloned files are intact. Then, note that the version of Nodejs should be 4.0+ and npm 3.0+. Finally, activate development:

The default language of Element is Chinese. If you wish to use another language, you'll need to do some i18n configuration. In your entry file, if you are importing Element entirely:
```javascript
importVuefrom'vue'
importElementUIfrom'element-ui'
importlocalefrom'element-ui/lib/locale/lang/en'
Vue.use(ElementUI,{locale})
```
Or if you are importing Element on demand:
```javascript
importVuefrom'vue'
import{Button,Select}from'element-ui'
importlangfrom'element-ui/lib/locale/lang/en'
importlocalefrom'element-ui/lib/locale'
// configure language
locale.use(lang)
// import components
Vue.component(Button.name,Button)
Vue.component(Select.name,Select)
```
The Chinese language pack is imported by default, even if you're using another language. But with `IgnorePlugin` provided by webpack you can ignore it when building:
Currently Element ships with the following languages:
- Chinese
- English
- German
- Portuguese
If your target language is not included, you are more than welcome to contribute: just add another language config [here](https://github.com/ElemeFE/element/tree/master/src/locale/lang) and create a pull request.
