-# Contributing
-
-The SheetJS Libraries should be free and clear to use in your projects.  In
-order to maintain that, every contributor must be vigilant.
-
-There have been many projects in the past that have been very lax regarding
-licensing, and we are of the opinion that those are ticking timebombs and that
-no commercial product should depend on them.
-
-
-# Required Reading
-
-These are pretty short reads and emphasize the importance of proper licensing:
-
- https://github.com/jazzband/tablib/issues/114 (discussion of other tools)
-
- https://web.archive.org/web/20120615223756/http://www.codinghorror.com/blog/2007/04/pick-a-license-any-license.html
-
-
-# Raising Issues
-
-Issues should generally be accompanied by test files.  Since github does not
-support attachments, the best method is to send files to <sheetjs@gmail.com>
-(subject line should contain issue number or message) or to share using some
-storage service.  Unless expressly permitted, any attachments will not be
-shared or included in a test suite (although I will ask :)
-
-If sending email to a gmail account is problematic, the <dev@sheetjs.com> email
-inbox is self-hosted.
-
-# Opening Pull Requests
-
-Before opening a pull request, [squash all commits into 
-one](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History). If the pull 
-request addresses documentation or demos, add `[ci skip]` in the body or title 
-of your commit message to skip Travis checks.
-
-# Pre-Contribution Checklist
-
-Before thinking about contributing, make sure that:
-
- You are not, nor have ever been, an employee of Microsoft Corporation.
-
- You have not signed any NDAs or Shared Source Agreements with Microsoft
-  Corporation or a subsidiary
-
- You have not consulted any existing relevant codebase (if you have, please
-  take note of which codebases were consulted).
-
-If you cannot attest to each of these items, the best approach is to raise an
-issue.  If it is a particularly high-priority issue, please drop an email to
-<sheetjs@gmail.com> and it will be prioritized.
-
-
-# Intra-Contribution
-
-Keep these in mind as you work:
-
- Your contributions are your original work.  Take note of any resources you
-  consult in the process (and be extra careful not to use unlicensed code on
-  the internet.
-
- You are working on your own time.  Unless they explicitly grant permission,
-  your employer may be the ultimate owner of your IP
-
-# Post-Contribution
-
-Before contributions are merged, you will receive an email (at the address
-associated with the git commit) and will be asked to confirm the aforementioned
-items.  Ensure that the email addresses associated with the commits are valid.

-      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
-      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.
