+# Node.js Core Working Groups
+
+Node.js Core Working Groups are autonomous projects created by the
+[Core Technical Committee (CTC)](https://github.com/nodejs/node/blob/master/GOVERNANCE.md#core-technical-committee).
+
+Working Groups can be formed at any time but must be ratified by the CTC.
+Once formed the work defined in the Working Group charter is the
+responsibility of the WG rather than the CTC.
+
+It is important that Working Groups are not formed pre-maturely. Working
+Groups are not formed to *begin* a set of tasks but instead are formed
+once that work is already underway and the contributors
+think it would benefit from being done as an autonomous project.
+
+If the work defined in a Working Group's charter is complete, the charter
+should be revoked.
+
+A Working Group's charter can be revoked either by consensus of the Working
+Group's members or by a CTC vote. Once revoked, any future work that arises
+becomes the responsibility of the CTC.
+
+## Joining a WG
+
+To find out how to join a working group, consult the GOVERNANCE.md in
+the working group's repository, or in the working group's repository.
+
+## Starting A Core Working Group
+
+The process to start a Core Working Group is identical to [creating a
+Top Level Working Group](https://github.com/nodejs/TSC/blob/master/WORKING_GROUPS.md#starting-a-wg).
+
+## Current Working Groups
+
+* [Website](#website)
+* [Streams](#streams)
+* [Build](#build)
+* [Diagnostics](#diagnostics)
+* [i18n](#i18n)
+* [Evangelism](#evangelism)
+* [Docker](#docker)
+* [Addon API](#addon-api)
+* [Benchmarking](#benchmarking)
+* [Post-mortem](#post-mortem)
+* [Intl](#intl)
+* [Documentation](#documentation)
+* [Testing](#testing)
+
+
+### [Website](https://github.com/nodejs/nodejs.org)
+
+The website Working Group's purpose is to build and maintain a public
+website for the Node.js project.
+
+Responsibilities include:
+* Developing and maintaining a build and automation system for nodejs.org.
+* Ensuring the site is regularly updated with changes made to Node.js, like
+  releases and features.
+* Fostering and enabling a community of translators.
+
+### [Streams](https://github.com/nodejs/readable-stream)
+
+The Streams Working Group is dedicated to the support and improvement of the
+Streams API as used in Node.js and the npm ecosystem. We seek to create a
+composable API that solves the problem of representing multiple occurrences
+of an event over time in a humane, low-overhead fashion. Improvements to the
+API will be driven by the needs of the ecosystem; interoperability and
+backwards compatibility with other solutions and prior versions are paramount
+in importance.
+
+Responsibilities include:
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance notice of
+  changes.
+
+### [Build](https://github.com/nodejs/build)
+
+The Build Working Group's purpose is to create and maintain a distributed
+automation infrastructure.
+
+Responsibilities include:
+* Producing packages for all target platforms.
+* Running tests.
+* Running performance testing and comparisons.
+* Creating and managing build-containers.
+
+### [Diagnostics](https://github.com/nodejs/diagnostics)
+
+The Diagnostics Working Group's purpose is to surface a set of comprehensive,
+documented, and extensible diagnostic interfaces for use by Node.js tools and
+JavaScript VMs.
+
+Responsibilities include:
+* Collaborating with V8 to integrate `v8_inspector` into Node.js.
+* Collaborating with V8 to integrate `trace_event` into Node.js.
+* Collaborating with Core to refine `async_wrap` and `async_hooks`.
+* Maintaining and improving OS trace system integration (e.g. ETW, LTTNG, dtrace).
+* Documenting diagnostic capabilities and APIs in Node.js and its components.
+* Exploring opportunities and gaps, discussing feature requests, and addressing
+  conflicts in Node.js diagnostics.
+* Fostering an ecosystem of diagnostics tools for Node.js.
+
+### i18n
+
+The i18n Working Groups handle more than just translations. They
+are endpoints for community members to collaborate with each
+other in their language of choice.
+
+Each team is organized around a common spoken language. Each
+language community might then produce multiple localizations for
+various project resources.
+
+Responsibilities include:
+* Translating any Node.js materials they believe are relevant to their
+  community.
+* Reviewing processes for keeping translations up to date and of high quality.
+* Managing and monitoring social media channels in their language.
+* Promoting Node.js speakers for meetups and conferences in their language.
+
+Note that the i18n Working Groups are distinct from the [Intl](#Intl) Working Group.
+
+Each language community maintains its own membership.

+and improvement of postmortem debugging for Node.js. It seeks to
+elevate the role of postmortem debugging for Node, to assist in the
+development of techniques and tools, and to make techniques and tools
+known and available to Node.js users.
+
+Responsibilities include:
+* Defining and adding interfaces/APIs in order to allow dumps
+  to be generated when needed.
+* Defining and adding common structures to the dumps generated
+  in order to support tools that want to introspect those dumps.
+
+### [Documentation](https://github.com/nodejs/docs)
+
+The Documentation Working Group exists to support the improvement of Node.js
