+Contribution Rules
+==================
+
+.. role:: bash(code)
+   :language: bash
+
+Coding Guidelines
+-----------------
+
+* We follow `Google C++ Style Guide <https://google.github.io/styleguide/cppguide.html>`_. When no
+  rules can be found, follow the already occuring conventions. If there is no precedence in our
+  codebase we are open to discussion.
+* Prior to your contribution, please make sure that the code passes the linter check. We do both C++
+  and Python linting. To invoke the check, please use
+
+  .. code-block:: bash
+
+    TE_PATH=<path to TE source> bash qa/L0_lint/test.sh
+
+* Avoid introducing unnecessary complexity into existing code so that maintainability and
+  readability are preserved.
+* Try to keep pull requests (PRs) as concise as possible:
+
+  - Avoid committing commented-out code.
+  - Wherever possible, each PR should address a single concern. If there are several
+    otherwise-unrelated things that should be fixed to reach a desired endpoint, our recommendation
+    is to open several PRs and indicate the dependencies in the description. The more complex the
+    changes are in a single PR, the more time it will take to review those changes.
+
+* Write PR and commit titles using imperative mood.
+
+  - Format commit messages sticking to rules described in
+    `this <https://chris.beams.io/posts/git-commit/>`_ guide.
+
+* Make sure all `L0_*` tests pass:
+
+  - In the :bash:`qa/` directory, there are basic sanity tests scripted in directories named
+    `L0_...`. A given test can be executed by running the :bash:`./test.sh` command in each test
+    directory. The :bash:`test.sh` script assume that the TE source can be found under
+    :bash:`/opt/transformerengine`. This assumption can be changed by setting :bash:`TE_PATH`
+    environment variable to the directory containing TE source.
+  - One of the tests, `L0_license` tests for valid NVIDIA copyright and license text. If you create
+    a new file and do not want to pass copyright rights to NVIDIA, please add the file to the
+    `exclude_copyright` list in :bash:`qa/L0_license/config.json`.
+
+* Transformer Engine's default build assumes recent versions of TE's dependencies (CUDA toolkit
+  etc.). Contributions that add compatibility with older versions of those dependencies will be
+  considered, but NVIDIA cannot guarantee that all possible build configurations work, are not
+  broken by future contributions, and retain highest performance.
+* Make sure that you can contribute your work to open source (no license and/or patent conflict is
+  introduced by your code). You need to `Sign Your Work`_.
+* Thanks in advance for your patience as we review your contributions; we do appreciate them!
+
+Sign Your Work
+--------------
+
+* We require that all contributors "sign-off" on their commits. This certifies that the contribution
+  is your original work, or you have rights to submit it under the same license, or a compatible
+  license.
+
+  * Any contribution which contains commits that are not Signed-Off will not be accepted.
+
+* To sign off on a commit you simply use the `--signoff` (or `-s`) option when committing your changes:
+
+  .. code-block:: bash
+
+    $ git commit -s -m "Add cool feature."
+
+  This will append the following to your commit message:
+
+  .. code-block:: text
+
+    Signed-off-by: Your Name <[email protected]>

+      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,

+      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

+          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.
