+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:
+
+You must give any other recipients of the Work or Derivative Works a copy of this License; and
+You must cause any modified files to carry prominent notices stating that You changed the files; and
+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
+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.
