We are excited that you are interested in contributing to Element. Before submitting your contribution though, please make sure to take a moment and read through the following guidelines.
- Issues are exclusively for bug reports, feature requests and design-related topics. Other questions may be closed directly. If any questions come up when you are using Element, please hit [Gitter](https://gitter.im/element-en/Lobby) for help.
- Please specify which version of `Element` and `Vue` you are using, and provide OS and browser information. [JSFiddle](https://jsfiddle.net/) is recommended to build a live demo so that your issue can be reproduced clearly.
- For the sake of compatibility and file size, our babel configuration only imported `preset-2015`, so APIs like `Array.prototype.find` and `Object.assign` in `ES2015` are not recommended. You can import third party polyfills if necessary.
`Node.js 4+`, `yarn` and `npm 3+` are required. Note: we use yarn to lock dependency versions, so you should install dependencies using `yarn` instead of `npm install`.
> **Notice**: modify `examples/play/index.vue` file, use the component you contribute, then run `npm run dev:play`, go ahead [http://localhost:8085](http://localhost:8085), get result, more quickly and friendly.
