+
+      An important design goal of ECharts is keeping the API surface small and straightforward. In general, we only consider adding new features that solve a problem that cannot be easily dealt with using existing APIs (i.e. not just an alternative way of doing things that can already be done). The problem should also be common enough to justify the addition.

+# 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 with the issues
+    - Help solve problems with the issues
+    - Remind the authors to provide a demo if they are reporting a bug
+    - Try to reproduce the problem as described in the issues
+- Make pull requests to fix bugs or implement new features
+- Improve or translate the documents
+- Discuss in the [mailing list](https://echarts.apache.org/en/maillist.html)
+- ...
+
+## Issues
+
+We have already prepared issue templates for bug reports and feature requests. If you want to fire an issue, just enter the [New issue](https://github.com/apache/echarts/issues/new/choose) page and select either of them to get started.
+
+Additionally, before doing so, please search for similar questions in our [issues list](https://github.com/apache/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 the features of each release in the [mailing list](https://echarts.apache.org/en/maillist.html). You may subscribe to our [mailing list](https://echarts.apache.org/en/maillist.html) to give your valuable advice in milestone discussions.
+
+Regarding the release plan, we will release a minor 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 the milestone of the release two versions ahead, which is 4.5.0 at the beginning of each month. At this time, we should also kick off the development of the next release, which is 4.4.0.
+2. Finish 4.4.0 development on about the 22nd 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/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/echarts/wiki/How-to-make-a-pull-request)

+
+## Some hints about using code from other authors
+
++ About using some algorithms/formulas or inspired by others' work:
+    + We can be inspired by other people’s work. There is no problem with copying ideas and no problems associated with that as 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 at: 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 Overflow, we must check the following:
+    + https://apache.org/legal/resolved.html#stackoverflow
+    + https://issues.apache.org/jira/browse/LEGAL-471
++ Wikipedia (and most Wikimedia Foundation projects):
+    + Wikipedia, and most Wikimedia Foundation projects, are licensed under CC 4.0 BY_SA (and sometimes GFDL) and are incompatible with the Apache license. Therefore, we should not copy code from Wikipedia or Wikimedia Foundation projects.

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "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
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      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
+      institute patent litigation against any entity (including a
+      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
+          Derivative Works a copy of this License; and
+
+      (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

+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
+
+# Rebuild source code immediately in watch mode when changing the source code.
+# It opens the `./test` directory, and you may open `-cases.html` to get the list
+# of all test cases.
+# If you wish to create a test case, run `npm run mktest:help` to learn more.
+npm run dev
+
+# Check the correctness of TypeScript code.
+npm run checktype
+
+# If intending to build and get all types of the "production" files:
+npm run release
+```
+
+Then the "production" files are generated in the `dist` directory.
