+## Overview
+
+The purpose of this document is to provide information regarding the communication channels for OpenSearch Dashboards. All communication is subject to the [OpenSearch Code of Conduct](CODE_OF_CONDUCT.md). Please see [CONTRIBUTING](CONTRIBUTING.md) if you're interested in contributing to the project.
+
+## Slack
+
+The OpenSearch project has a public workspace on [Slack](https://opensearch.slack.com). See the [Getting Started guide]() for steps to register and setup the workspace.
+
+Once registered, check out these channels for discussion of OpenSearch Dashboards topics:
+
+- [#dashboards](https://opensearch.slack.com/archives/C01QENNTGUD)
+- [#dashboards-ux](https://opensearch.slack.com/archives/C05389T9LJC)
+
+## Forum
+
+Slack conversations are not searchable outside the workspace. For this reason we encourage using the [OpenSearch Dashboards category](https://forum.opensearch.org/c/opensearch-dashboards/57) of the forum for technical support discussions or summarizing findings for the rest of the community.
+
+## Developer Office Hours
+
+### What it is
+
+A recurring 1-hour virtual meeting for community developers to chat with [OpenSearch Dashboards project maintainers](MAINTAINERS.md). Priority will be given to topics that are signed-up in advance, but ad-hoc discussions are welcome in any remaining time.
+
+While we'll always prioritize asynchronous communication, sometimes a community call is the most effective and efficient venue to share information and knowledge. Some reasons to sign up:
+
+1. Review a proposal or technical design for a new feature in OpenSearch Dashboards or an OpenSearch Dashboards plugin
+2. Learn more about how to build and extend OpenSearch Dashboards - which APIs, plugins, resources, and services are available to speed development
+3. Discuss OpenSearch Dashboards roadmap and technical initiatives
+
+Signing up isn't required to attend - all OpenSearch Dashboards contributors or interested developers are welcome as participants.
+
+Bring your ideas and projects early, while you still have time and flexibility to make significant changes.
+
+### When
+
+Every other Thursday, 10AM-11AM PT.
+
+### How to sign up
+
+There will be a forum post for each iteration of the meeting, with pre-defined slots. To sign-up, simply reply in the forum thread with the following template:
+
+* Topic: [a brief description of what you'd like to discuss]
+* Requested by: [provide GitHub aliases of attendees]
+* GitHub issues or PRs: [before signing up, make sure to create an issue, whether in the OpenSearch Dashboards repository or your own plugin repository]
+* Time required [choose 15, 30, 45, or 60 minutes]
+* Requested maintainer: [optional; provide GitHub alias of any particular maintainer you’d like to attend]
+
+### FAQ
+
+#### Will the meetings be recorded?
+
+Yes, we plan to record each office hours session and post to our YouTube channel so the information can be more easily shared and referenced.
+
+#### Will all maintainers attend?
+
+Generally no, but there will always be at least one maintainer. We'll review the sign-ups ahead of time to make sure the right subject-matter experts will attend, depending on the topics.
+
+#### What happens if there are no sign-ups for a particular session?
+
+The session will still occur, and the maintainers will present a brief knowledge-sharing session or demo. We'll also hold ad-hoc discussions, but the session may end early.
+
+#### Is it first come first serve or do we get to decide which topics we discuss in a session?
+
+For sign-ups, it’s first-come first served, until we decide we need another method.
+
+#### Will there also be meeting notes? or is the recording the only available transcript?
+
+No. But we’ll also post the chat transcript and any slides shared (see https://forum.opensearch.org/t/opensearch-community-meeting-2023-0131/11892/5 as example)
+
+#### How can I cancel or reschedule?
+
+Just leave another forum reply, as early as possible so other folks have the opportunity to sign-up for the same spot.
