+# Contributing
+
+👍🎉 First off, thanks for taking the time to contribute! 🎉👍
+
+Please check out the [Apache Code of Conduct](https://www.apache.org/foundation/policies/conduct.html) first.
+
+## What can you do for the ECharts community?
+
+Contributions can be made in varied ways:
+
+- Help others in the issues
+    - Help solve problems with the issues
+    - Remind the authors to provide a demo if they are reporting for a bug
+    - Try to reproduce the problem as describe in the issues
+- Make pull requests to fix bugs or implement new features
+- Mend or translate the documents
+- Discuss in the [mailing list](https://echarts.apache.org/en/maillist.html)
+- ...
+
+## Issues
+
+When opening new issues, please use the [echarts issue helper](https://ecomfe.github.io/echarts-issue-helper/), opening issues in any other way will cause our bot to close them automatically.
+
+And before doing so, please search for similar questions in our [issues list](https://github.com/apache/incubator-echarts/issues?utf8=%E2%9C%93&q=is%3Aissue). If you are able to reproduce an issue found in a closed issue, please create a new issue and reference the closed one.
+
+Please read the [documentation](http://echarts.apache.org/option.html) carefully before asking any questions.
+
+Any questions in the form of *how can I use echarts to* or *how to use echarts x feature to* belong in [Stack Overflow](http://stackoverflow.com), issues with questions like that in the issue tracker will be closed.
+
+## Release Milestone Discussion
+
+We will start the discussion about the bugs to fix and features of each release in the [mailing list](https://echarts.apache.org/en/maillist.html). You may subscribe our [mailing list](https://echarts.apache.org/en/maillist.html) to give your valuable advice in the milestone dicussion.
+
+About our release plan, we will release a mior version at the end of every month. Here is some detail.
+
+1. Assume our current stable release is 4.3.0. We will start the discussion of milestone of the release two versions ahead, which is 4.5.0 at the beginning of each month. At this time we should also kickoff the developing of the next release, which is 4.4.0.
+2. Finish 4.4.0 developing at about 22th of this month and start the testing. And the 4.5.0 milestone discussion is frozen and published on the [GitHub](https://github.com/apache/incubator-echarts/milestone/14)
+3. Vote in the mailing list for the 4.4.0 release at the end of this month.
+
+## Pull Requests
+
+Wiki: [How to make a pull request](https://github.com/apache/incubator-echarts/wiki/How-to-make-a-pull-request)

+
+Wiki: [How to setup the dev environment](https://github.com/apache/incubator-echarts/wiki/How-to-setup-the-dev-environment)
+
+## Some hints about using code from other authors
+
++ About using some algorithms/formulas or inspired by other's work:
+    + We can be inspired from other people’s work. There is no problem with copying ideas and no problems associated with that so long as the code is entirely yours and you aren’t violating the license of the inspirational work. You can just follow "normal" source code rules.
+    + But when you copy the code, even parts of files, it must remain under the copyright of the original authors.
+    + What's the right thing to do for the public good here? I'll go with:
+        + Be transparent when implementing an existing idea/algorithm.
+        + Reference where that idea/algorithm came from.
+        + Use standard language when doing so (we need to define standard language).
+            + "inspired by", "learned from" and "references to" are vague concepts in copyright.
+        + If any copyrightable expression is copied from the existing idea/algorithm, compare its licensing to our licensing policies and include licensing accordingly.
+    + Check the original discussion about it in: https://lists.apache.org/list.html?legal-discuss@apache.org:lte=36M:echarts
++ About adding the license/header of 3rd-party work:
+    + https://www.apache.org/legal/src-headers.html#3party
++ Licenses that are compatible with the Apache license:
+    + BSD and MIT are compatible with the Apache license but CC_BY_SA is not (https://apache.org/legal/resolved.html#cc-sa).
++ Stack overflow:
+    + before intending to copy code from Stack overlow, we must check:
+    + https://apache.org/legal/resolved.html#stackoverflow
+    + https://issues.apache.org/jira/browse/LEGAL-471
++ Wikipedia:
+    + Wikipedia is licensed CC 4.0 BY_SA and is incompatible with the Apache license. So we should not copy code from Wikipedia.
++ Working in progress disclaimer:
+    + In some cases we might use the work in progress disclaimer and document the issues in that until they are fixed.
+    + https://incubator.apache.org/policy/incubation.html#disclaimers

+Apache ECharts (incubating) is an effort undergoing incubation at The
+Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.
+
+Incubation is required of all newly accepted
+projects until a further review indicates that the
+infrastructure, communications, and decision making process have
+stabilized in a manner consistent with other successful ASF
+projects.
+
+While incubation status is not necessarily a reflection
+of the completeness or stability of the code, it does indicate
+that the project has yet to be fully endorsed by the ASF.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+   APPENDIX: How to apply the Apache License to your work.

+## Build
+
+Build echarts source code:
+
+Execute the instructions in the root directory of the echarts:
+([Node.js](https://nodejs.org) is required)
+
+```shell
+# Install the dependencies from NPM:
+npm install
+
+# If intending to build and get all types of the "production" files:
+npm run release
+# The same as `node build/build.js --release`
+
+# If only intending to get `dist/echarts.js`, which is usually
+# enough in dev or running the tests:
+npm run build
+# The same as `node build/build.js`
+
+# Get the same "production" files as `node build/build.js`, while
+# watching the editing of the source code. Usually used in dev.
+npm run watch
+# The same as `node build/build.js -w`
+
+# Check the manual:
+npm run help
+# The same as `node build/build.js --help`
+```
+
+Then the "production" files are generated in the `dist` directory.
+
+More custom build approaches can be checked in this tutorial: [Create Custom Build of ECharts](https://echarts.apache.org/en/tutorial.html#Create%20Custom%20Build%20of%20ECharts) please.

+## 百度地图扩展
+
+ECharts 百度地图扩展，可以在百度地图上展现 [点图](http://echarts.baidu.com/option.html#series-scatter)，[线图](http://echarts.baidu.com/option.html#series-line)，[热力图](http://echarts.baidu.com/option.html#series-heatmap) 等可视化。
+
+
+### 示例
+
+[全国主要城市空气质量](http://echarts.baidu.com/demo.html#effectScatter-bmap)
+
+[北京公交路线](http://echarts.baidu.com/demo.html#lines-bmap-bus)
+
+[北京公交路线特效](http://echarts.baidu.com/demo.html#lines-bmap-effect)
+
+[北京公交路线特效](http://echarts.baidu.com/demo.html#lines-bmap-effect)
+
+[杭州热门步行路线](http://echarts.baidu.com/demo.html#heatmap-bmap)
+
+
+### 引入
+
+可以直接引入打包好的扩展文件和百度地图的 jssdk
+
+```html
+<!--引入百度地图的jssdk，这里需要使用你在百度地图开发者平台申请的 ak-->
+<script src="http://api.map.baidu.com/api?v=2.0&ak="></script>
+<!-- 引入 ECharts -->
+<script src="dist/echarts.min.js"></script>
+<!-- 引入百度地图扩展 -->
+<script src="dist/extension/bmap.min.js"></script>
+```
+
+如果是 webpack 打包，也可以 require 引入
+
+```js
+require('echarts');
+require('echarts/extension/bmap/bmap');
+```
+
+插件会自动注册相应的组件。
+
+### 使用
+
+扩展主要提供了跟 geo 一样的坐标系和底图的绘制，因此配置方式非常简单，如下
+
+```js
+option = {
+    // 加载 bmap 组件
+    bmap: {
+        // 百度地图中心经纬度
+        center: [120.13066322374, 30.240018034923],
+        // 百度地图缩放
+        zoom: 14,
+        // 是否开启拖拽缩放，可以只设置 'scale' 或者 'move'
+        roam: true,
+        // 百度地图的自定义样式，见 http://developer.baidu.com/map/jsdevelop-11.htm
+        mapStyle: {}
+    },
+    series: [{
+        type: 'scatter',
+        // 使用百度地图坐标系
+        coordinateSystem: 'bmap',
+        // 数据格式跟在 geo 坐标系上一样，每一项都是 [经度，纬度，数值大小，其它维度...]
+        data: [ [120, 30, 1] ]
+    }]
+}
+
+// 获取百度地图实例，使用百度地图自带的控件
+var bmap = chart.getModel().getComponent('bmap').getBMap();
+bmap.addControl(new BMap.MapTypeControl());
+```
+
