-# Docker Governance Advisory Board Meetings

-In the spirit of openness, Docker created a Governance Advisory Board, and committed to make all materials and notes from the meetings of this group public.
-All output from the meetings should be considered proposals only, and are subject to the review and approval of the community and the project leadership.
+Moby projects are governed by the [Moby Technical Steering Committee (TSC)](https://github.com/moby/tsc).
+See the Moby TSC [charter](https://github.com/moby/tsc/blob/master/README.md) for
+further information on the role of the TSC and procedures for escalation
+of technical issues or concerns.
-The materials from the first Docker Governance Advisory Board meeting, held on October 28, 2014, are available at
-[Google Docs Folder](https://goo.gl/Alfj8r)
+Contact [any Moby TSC member](https://github.com/moby/tsc/blob/master/MEMBERS.md) with your questions/concerns about the governance or a specific technical
+issue that you feel requires escalation.
-These include:
+## Project maintainers
-* First Meeting Notes
-* DGAB Charter
-* Presentation 1: Introductory Presentation, including State of The Project
-* Presentation 2: Overall Contribution Structure/Docker Project Core Proposal
-* Presentation 3: Long Term Roadmap/Statement of Direction
-
+The current maintainers of the moby/moby repository are listed in the
+[MAINTAINERS](/MAINTAINERS) file.
+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 less visible.
+It's easy to recognize 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.
+
+### Adding maintainers
+
+Maintainers are first and foremost contributors who have shown their
+commitment to the long term success of a project. Contributors who want to
+become maintainers first demonstrate commitment to the project by contributing
+code, reviewing others' work, and triaging issues on a regular basis for at
+least three months.
+
+The contributions alone don't make you a maintainer. You need to earn the
+trust of the current maintainers and other project contributors, that your
+decisions and actions are in the best interest of the project.
+
+Periodically, the existing maintainers curate a list of contributors who 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 is announced on the maintainers mailing list, the
+existing maintainers discuss the candidate over the next 5 business days,
+provide feedback, and vote. At least 66% of the current maintainers must
+vote in the affirmative.
+
+If a candidate is approved, a maintainer contacts the candidate to
+invite them to open a pull request that adds the contributor to
+the MAINTAINERS file. The candidate becomes a maintainer once the pull
+request is merged.
+
+### Removing maintainers
+
+Maintainers can be removed from the project, either at their own request
+or due to [project inactivity](#inactive-maintainer-policy).
+
+#### How to step down
+
+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.
+
+#### Inactive maintainer policy
+
+An existing maintainer can be removed 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 project
+representative 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 continue in this role, but is unable to perform the
+required duties, they can be removed with a vote by at least 66% of the current
+maintainers. The maintainer under discussion will not be allowed to vote. An
+e-mail is sent to the mailing list, inviting maintainers of the project to
+vote. The voting period is five business days. Issues related to a maintainer's
+performance should be discussed with them among the other maintainers so that
+they are not surprised by a pull request removing them. This discussion should
+be handled objectively with no ad hominem attacks.
+
+## Project decision making
+
+Short answer: **Everything is a pull request**.
+
+The Moby core engine project 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, each decision can be expressed as a change to the repository. An
+implementation change is expressed as 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 the moby/moby repository, both big and small, follow
+the same steps:
+
+ * **Step 1**: Open a pull request. Anyone can do this.
+
+ * **Step 2**: Discuss the pull request. Anyone can do this.
+
+ * **Step 3**: Maintainers merge, close or reject the pull request.
+
+Pull requests are reviewed by the current maintainers of the moby/moby
+repository. Weekly meetings are organized to are organized to synchronously
+discuss tricky PRs, as well as design and architecture decisions.. When
+technical agreement cannot be reached among the maintainers of the project,
+escalation or concerns can be raised by opening an issue to be handled
+by the [Moby Technical Steering Committee](https://github.com/moby/tsc).
