+
+## Reporting security issues
+
+The maintainers take security seriously. If you discover a security
+issue, please bring it to their attention right away!
+
+Please **DO NOT** file a public issue, instead send your report privately to
+[cncf-distribution-security@lists.cncf.io](mailto:cncf-distribution-security@lists.cncf.io).
+
+## Reporting an issue properly
+
+By following these simple rules you will get better and faster feedback on your issue.
+
+ - search the bugtracker for an already reported issue
+
+### If you found an issue that describes your problem:
+
+ - please read other user comments first, and confirm this is the same issue: a given error condition might be indicative of different problems - you may also find a workaround in the comments
+ - please refrain from adding "same thing here" or "+1" comments
+ - you don't need to comment on an issue to get notified of updates: just hit the "subscribe" button
+ - comment if you have some new, technical and relevant information to add to the case
+ - __DO NOT__ comment on closed issues or merged PRs. If you think you have a related problem, open up a new issue and reference the PR or issue.
+
+### If you have not found an existing issue that describes your problem:
+
+ 1. create a new issue, with a succinct title that describes your issue:
+   - bad title: "It doesn't work with my docker"
+   - good title: "Private registry push fail: 400 error with E_INVALID_DIGEST"
+ 2. copy the output of (or similar for other container tools):
+   - `docker version`
+   - `docker info`
+   - `docker exec <registry-container> registry --version`
+ 3. copy the command line you used to launch your Registry
+ 4. restart your docker daemon in debug mode (add `-D` to the daemon launch arguments)
+ 5. reproduce your problem and get your docker daemon logs showing the error
+ 6. if relevant, copy your registry logs that show the error
+ 7. provide any relevant detail about your specific Registry configuration (e.g., storage backend used)
+ 8. indicate if you are using an enterprise proxy, Nginx, or anything else between you and your Registry
+
+## Contributing Code
+
+Contributions should be made via pull requests. Pull requests will be reviewed
+by one or more maintainers or reviewers and merged when acceptable.
+
+You should follow the basic GitHub workflow:
+
+ 1. Use your own [fork](https://help.github.com/en/articles/about-forks)
+ 2. Create your [change](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
+ 3. Test your code
+ 4. [Commit](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages) your work, always [sign your commits](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages)
+ 5. Push your change to your fork and create a [Pull Request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork)
+
+Refer to [containerd's contribution guide](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
+for tips on creating a successful contribution.
+
+## Sign your work
+
+The sign-off is a simple line at the end of the explanation for the patch. Your
+signature certifies that you wrote the patch or otherwise have the right to pass
+it on as an open-source patch. The rules are pretty simple: if you can certify
+the below (from [developercertificate.org](http://developercertificate.org/)):
+
+```

+Version 1.1

+660 York Street, Suite 102,
+San Francisco, CA 94110 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+Then you just add a line to every git commit message:
+
+    Signed-off-by: Joe Smith <joe.smith@email.com>
+
+Use your real name (sorry, no pseudonyms or anonymous contributions.)
+
+If you set your `user.name` and `user.email` git configs, you can sign your
+commit automatically with `git commit -s`.

+
+## Maintainership
+
+There are different types of maintainers, with different responsibilities, but
+all maintainers have 3 things in common:
+
+1) They share responsibility in the project's success.
+2) They have made a long-term, recurring time investment to improve the project.
+3) They spend that time doing whatever needs to be done, not necessarily what
+is the most interesting or fun.
+
+Maintainers are often under-appreciated, because their work is harder to appreciate.
+It's easy to appreciate a really cool and technically advanced feature. It's harder
+to appreciate the absence of bugs, the slow but steady improvement in stability,
+or the reliability of a release process. But those things distinguish a good
+project from a great one.
+
+## Reviewers
+
+A reviewer is a core role within the project.
+They share in reviewing issues and pull requests and their LGTM counts towards the
+required LGTM count to merge a code change into the project.
+
+Reviewers are part of the organization but do not have write access.
+Becoming a reviewer is a core aspect in the journey to becoming a maintainer.
+
+## Adding maintainers
+
+Maintainers are first and foremost contributors that have shown they are
+committed to the long term success of a project. Contributors wanting to become
+maintainers are expected to be deeply involved in contributing code, pull
+request review, and triage of issues in the project for more than three months.
+
+Just contributing does not make you a maintainer, it is about building trust
+with the current maintainers of the project and being a person that they can
+depend on and trust to make decisions in the best interest of the project.
+
+Periodically, the existing maintainers curate a list of contributors that have
+shown regular activity on the project over the prior months. From this list,
+maintainer candidates are selected and proposed in a pull request or a
+maintainers communication channel.
+
+After a candidate has been announced to the maintainers, the existing
+maintainers are given five business days to discuss the candidate, raise
+objections and cast their vote. Votes may take place on the communication
+channel or via pull request comment. Candidates must be approved by at least 66%
+of the current maintainers by adding their vote on the mailing list. The
+reviewer role has the same process but only requires 33% of current maintainers.
+Only maintainers of the repository that the candidate is proposed for are
+allowed to vote.
+
+If a candidate is approved, a maintainer will contact the candidate to invite
+the candidate to open a pull request that adds the contributor to the
+MAINTAINERS file. The voting process may take place inside a pull request if a
+maintainer has already discussed the candidacy with the candidate and a
+maintainer is willing to be a sponsor by opening the pull request. The candidate
+becomes a maintainer once the pull request is merged.
+
+## Stepping down policy
+
+Life priorities, interests, and passions can change. If you're a maintainer but
+feel you must remove yourself from the list, inform other maintainers that you
+intend to step down, and if possible, help find someone to pick up your work.
+At the very least, ensure your work can be continued where you left off.
+
+After you've informed other maintainers, create a pull request to remove
+yourself from the MAINTAINERS file.
+
+## Removal of inactive maintainers
+
+Similar to the procedure for adding new maintainers, existing maintainers can
+be removed from the list if they do not show significant activity on the
+project. Periodically, the maintainers review the list of maintainers and their
+activity over the last three months.
+
+If a maintainer has shown insufficient activity over this period, a neutral
+person will contact the maintainer to ask if they want to continue being
+a maintainer. If the maintainer decides to step down as a maintainer, they
+open a pull request to be removed from the MAINTAINERS file.
+
+If the maintainer wants to remain a maintainer, but is unable to perform the
+required duties they can be removed with a vote of at least 66% of the current
+maintainers. In this case, maintainers should first propose the change to
+maintainers via the maintainers communication channel, then open a pull request
+for voting. The voting period is five business days. The voting pull request
+should not come as a surpise to any maintainer and any discussion related to
+performance must not be discussed on the pull request.
+
+## How are decisions made?
+
+Docker distribution is an open-source project with an open design philosophy.
+This means that the repository is the source of truth for EVERY aspect of the
+project, including its philosophy, design, road map, and APIs. *If it's part of
+the project, it's in the repo. If it's in the repo, it's part of the project.*
+
+As a result, all decisions can be expressed as changes to the repository. An
+implementation change is a change to the source code. An API change is a change
+to the API specification. A philosophy change is a change to the philosophy
+manifesto, and so on.
+
+All decisions affecting distribution, big and small, follow the same 3 steps:
+
+* Step 1: Open a pull request. Anyone can do this.
+
+* Step 2: Discuss the pull request. Anyone can do this.
+
+* Step 3: Merge or refuse the pull request. Who does this depends on the nature
+of the pull request and which areas of the project it affects.
+
+## Helping contributors with the DCO
+
+The [DCO or `Sign your work`](./CONTRIBUTING.md#sign-your-work)
+requirement is not intended as a roadblock or speed bump.
+
+Some contributors are not as familiar with `git`, or have used a web
+based editor, and thus asking them to `git commit --amend -s` is not the best
+way forward.
+
+In this case, maintainers can update the commits based on clause (c) of the DCO.
+The most trivial way for a contributor to allow the maintainer to do this, is to
+add a DCO signature in a pull requests's comment, or a maintainer can simply
+note that the change is sufficiently trivial that it does not substantially
+change the existing contribution - i.e., a spelling change.
+
+When you add someone's DCO, please also add your own to keep a log.
+
+## I'm a maintainer. Should I make pull requests too?
+
+Yes. Nobody should ever push to master directly. All changes should be
+made through a pull request.
+
+## Conflict Resolution
+
+If you have a technical dispute that you feel has reached an impasse with a
+subset of the community, any contributor may open an issue, specifically

+
+      "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

+      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
+      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.
+
