Hi, I found our documentation about 'How to Contribute' is in the .github/CONTRIBUTING.md [1] . It's not easy to be found. Should we move it to the root folder instead of a hidden .github folder. It can also be included in the source release.
BTW, I think we also need a 'How to Contribute' page in the website. [1] https://github.com/apache/incubator-echarts/blob/master/.github/CONTRIBUTING.md -- Yi Shen Senior Developer Baidu, Inc.
