+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.

+A reviewer is a core role within the project.
+They share in reviewing issues and pull requests and their LGTM count 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.

+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 on the maintainers mailing list.
+
+After a candidate has been announced on the maintainers mailing list, the
+existing maintainers are given five business days to discuss the candidate,
+raise objections and cast their vote. Candidates must be approved by at least 66% of the current maintainers by adding their vote on the mailing
+list. 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 candidate becomes a maintainer once the pull request is
+merged.

+Similar to the procedure for adding new maintainers, existing maintainers can

+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. An e-mail is sent to the
+mailing list, inviting maintainers of the project to vote. The voting period is

+Short answer: EVERYTHING IS A PULL REQUEST.
+
+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.

+The [DCO or `Sign your work`](

+
+Some distribution 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.

-## Registry Release Checklist
-
-10. Compile release notes detailing features and since the last release.
-
-  Update the `CHANGELOG.md` file and create a PR to master with the updates.
-Once that PR has been approved by maintainers the change may be cherry-picked
-to the release branch (new release branches may be forked from this commit).
-
-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, use previous tags as a guide for formatting consistently. Run
-`git tag -s vx.y.z[-rcn]` to create tag and `git -v vx.y.z[-rcn]` to verify tag,
-check comment and correct commit hash.
-
-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.
