-## Coding Style
+    Signed-off-by: Joe Smith <joe.smith@email.com>
 
-Unless explicitly stated, we follow all coding guidelines from the Go
-community. While some of these standards may seem arbitrary, they somehow seem
-to result in a solid, consistent codebase.
+Use your real name (sorry, no pseudonyms or anonymous contributions.)
 
-It is possible that the code base does not currently comply with these
-guidelines. We are not looking for a massive PR that fixes this, since that
-goes against the spirit of the guidelines. All new contributions should make a
-best effort to clean up and make the code base better than they left it.
-Obviously, apply your best judgement. Remember, the goal here is to make the
-code base easier for humans to navigate and understand. Always keep that in
-mind when nudging others to comply.
-
-The rules:
-
-1. All code should be formatted with `gofmt -s`.
-2. All code should pass the default levels of
-   [`golint`](https://github.com/golang/lint).
-3. All code should follow the guidelines covered in [Effective
-   Go](http://golang.org/doc/effective_go.html) and [Go Code Review
-   Comments](https://github.com/golang/go/wiki/CodeReviewComments).
-4. Comment the code. Tell us the why, the history and the context.
-5. Document _all_ declarations and methods, even private ones. Declare
-   expectations, caveats and anything else that may be important. If a type
-   gets exported, having the comments already there will ensure it's ready.
-6. Variable name length should be proportional to its context and no longer.
-   `noCommaALongVariableNameLikeThisIsNotMoreClearWhenASimpleCommentWouldDo`.
-   In practice, short methods will have short variable names and globals will
-   have longer names.
-7. No underscores in package names. If you need a compound name, step back,
-   and re-examine why you need a compound name. If you still think you need a
-   compound name, lose the underscore.
-8. No utils or helpers packages. If a function is not general enough to
-   warrant its own package, it has not been written generally enough to be a
-   part of a util package. Just leave it unexported and well-documented.
-9. All tests should run with `go test` and outside tooling should not be
-   required. No, we don't need another unit testing framework. Assertion
-   packages are acceptable if they provide _real_ incremental value.
-10. Even though we call these "rules" above, they are actually just
-    guidelines. Since you've read all the rules, you now know that.
-
-If you are having trouble getting into the mood of idiomatic Go, we recommend
-reading through [Effective Go](http://golang.org/doc/effective_go.html). The
-[Go Blog](http://blog.golang.org/) is also a great resource. Drinking the
-kool-aid is a lot easier than going thirsty.
+If you set your `user.name` and `user.email` git configs, you can sign your
+commit automatically with `git commit -s`.

+# docker/distribution Project Governance
+
+Docker distribution abides by the [CNCF Code of Conduct](https://github.com/cncf/foundation/blob/master/code-of-conduct.md).
+
+For specific guidance on practical contribution steps please
+see our [CONTRIBUTING.md](./CONTRIBUTING.md) guide.
+
+## 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
+calling for a resolution vote of the current core maintainers to resolve the
+dispute. The same voting quorums required (2/3) for adding and removing
+maintainers will apply to conflict resolution.

-This project should provide an implementation to a V2 API for use in the [Docker
-core project](https://github.com/docker/docker). The API should be embeddable
-and simplify the process of securely pulling and pushing content from `docker`
-daemons.
+Clients implement against the OCI specification and communicate with the

-## Registry Release Checklist
-
-10. Compile release notes detailing features and since the last release.  Update the `CHANGELOG.md` file.
-
-20. Update the version file: `https://github.com/docker/distribution/blob/master/version/version.go`
-
-30. Update the `MAINTAINERS` (if necessary), `AUTHORS` and `.mailmap` files.
-
-    ```
-make AUTHORS
-```
-
-40. Create a signed tag.
-
-   Distribution uses semantic versioning.  Tags are of the format `vx.y.z[-rcn]`
-You will need PGP installed and a PGP key which has been added to your Github account.  The comment for the tag should include the release notes.
-
-50. Push the signed tag
-
-60. Create a new [release](https://github.com/docker/distribution/releases).  In the case of a release candidate, tick the `pre-release` checkbox. 
-
-70. Update the registry binary in [distribution library image repo](https://github.com/docker/distribution-library-image) by running the update script and  opening a pull request.
-
-80. Update the official image.  Add the new version in the [official images repo](https://github.com/docker-library/official-images) by appending a new version to the `registry/registry` file with the git hash pointed to by the signed tag.  Update the major version to point to the latest version and the minor version to point to new patch release if necessary.
-e.g. to release `2.3.1`
-
-   `2.3.1 (new)`
-
-   `2.3.0 -> 2.3.0` can be removed
-
-   `2 -> 2.3.1`
-
-   `2.3 -> 2.3.1`
-
-90. Build a new distribution/registry image on [Docker hub](https://hub.docker.com/u/distribution/dashboard) by adding a new automated build with the new tag and re-building the images.

+# Architecture
+
+## Design
+**TODO(stevvooe):** Discuss the architecture of the registry, internally and externally, in a few different deployment scenarios.
+
+### Eventual Consistency
+
+> **NOTE:** This section belongs somewhere, perhaps in a design document. We
+> are leaving this here so the information is not lost.
+
+Running the registry on eventually consistent backends has been part of the
+design from the beginning. This section covers some of the approaches to
+dealing with this reality.
+
+There are a few classes of issues that we need to worry about when
+implementing something on top of the storage drivers:
+
+1. Read-After-Write consistency (see this [article on
+   s3](http://shlomoswidler.com/2009/12/read-after-write-consistency-in-amazon.html)).
+2. [Write-Write Conflicts](http://en.wikipedia.org/wiki/Write%E2%80%93write_conflict).
+
+In reality, the registry must worry about these kinds of errors when doing the
+following:
+
+1. Accepting data into a temporary upload file may not have latest data block
+   yet (read-after-write).
+2. Moving uploaded data into its blob location (write-write race).
+3. Modifying the "current" manifest for given tag (write-write race).
+4. A whole slew of operations around deletes (read-after-write, delete-write
+   races, garbage collection, etc.).
+
+The backend path layout employs a few techniques to avoid these problems:
+
+1. Large writes are done to private upload directories. This alleviates most
+   of the corruption potential under multiple writers by avoiding multiple
+   writers.
+2. Constraints in storage driver implementations, such as support for writing
+   after the end of a file to extend it.
+3. Digest verification to avoid data corruption.
+4. Manifest files are stored by digest and cannot change.
+5. All other non-content files (links, hashes, etc.) are written as an atomic
+   unit. Anything that requires additions and deletions is broken out into
+   separate "files". Last writer still wins.
+
+Unfortunately, one must play this game when trying to build something like
+this on top of eventually consistent storage systems. If we run into serious
+problems, we can wrap the storagedrivers in a shared consistency layer but
+that would increase complexity and hinder registry cluster performance.

+## Image manifest version 2, schema 1
+With the release of image manifest version 2, schema 2, image manifest version
+2, schema 1 has been deprecated. This could lead to compatibility and
+vulnerability issues in images that haven't been updated to image manifest
+version 2, schema 2.
+
+This page contains information on how to update from image manifest version 2,
+schema 1. However, these instructions will not ensure your new image will run
+successfully. There may be several other issues to troubleshoot that are
+associated with  the deprecated image manifest that will block your image from
+running succesfully. A list of possible methods to help update your image is
+also included below.
+
+### Update to image manifest version 2, schema 2
+
+One way to upgrade an image from image manifest version 2, schema 1 to
+schema 2 is to `docker pull` the image and then `docker push` the image with a
+current version of Docker. Doing so will automatically convert the image to use
+the latest image manifest specification.
+
+Converting an image to image manifest version 2, schema 2 converts the
+manifest format, but does not update the contents within the image. Images
+using manifest version 2, schema 1 may contain unpatched vulnerabilities. We
+recommend looking for an alternative image or rebuilding it.
+
+
+### Update FROM statement
+
+You can rebuild the image by updating the `FROM` statement in your
+`Dockerfile`. If your image manifest is out-of-date, there is a chance the
+image pulled from your `FROM` statement in your `Dockerfile` is also
+out-of-date. See the [Dockerfile reference](https://docs.docker.com/engine/reference/builder/#from)
+and the [Dockerfile best practices guide](https://docs.docker.com/develop/develop-images/dockerfile_best-practices/)
+for more information on how to update the `FROM` statement in your
+`Dockerfile`.
