+Maintenance
+-----------
+
+If you are interested in moderating the chat or forum or accessing the social
+media accounts:
+
+* Matplotlib maintainers should reach out to the `community-manager`_.
+
+* Everyone else should send an email to [email protected]:
+
+  * Introduce yourself - github handle and participation in the community.
+  * Describe the reason for wanting to moderate or contribute to social.
+
+
+Content guidelines
+==================
+
+Communication on official channels, such as the Matplotlib homepage or on
+Matplotlib social accounts, should conform to the following standards. If you
+are unsure if content that you would like to post or share meets these
+guidelines, ask on the :ref:`social-media-coordination` channels before posting.
+
+General guidelines
+------------------
+
+* Focus on Matplotlib, 3rd party packages, and visualizations made with Matplotlib.
+* These are also acceptable topics:
+
+  * Visualization best practices and libraries.
+  * Projects and initiatives by NumFOCUS and Scientific Python.
+  * How to contribute to open source projects.
+  * Projects, such as scientific papers, that use Matplotlib.
+
+* No gratuitous disparaging of other visualization libraries and tools, but
+  criticism is acceptable so long as it serves a constructive purpose.
+
+* Follow communication best practices:
+
+  * Do not share non-expert visualizations when it could cause harm:
+
+    * e.g. https://twitter.com/matplotlib/status/1244178154618605568
+
+  * Clearly state when the visualization data/conclusions cannot be verified.
+  * Do not rely on machine translations for sensitive visualization.
+
+* Verify sourcing of content (especially on instagram & blog):
+
+  * Instagram/blog: ensure mpl has right to repost/share content
+  * Make sure content is clearly cited:
+
+    * e.g. a tutorial reworking an example must credit the original example
+
+* Limited self/corporate promotion is acceptable.
+
+  * Should be no more than about a quarter of the content.
+
+Visual media guidelines
+-----------------------
+
+Visual media, such as images and videos, must not violate the
+:ref:`code of conduct <code_of_conduct>`, nor any platform's rules.
+Specifically:
+
+* Visual media must conform to the guidelines of all sites it may be posted on:
+
+  * https://help.twitter.com/en/rules-and-policies/twitter-rules
+  * https://help.instagram.com/477434105621119
+
+* Emphasize the visualization techniques demonstrated by the visual media.
+* Clearly state that sharing is not an endorsement of the content.
+
+  * e.g. bitcoin related visualizations
+
+Accessibility
+^^^^^^^^^^^^^
+
+Visual media in communications should be made as accessible as possible:
+
+* Add alt text to images and videos when the platform allows:
+
+  * `alt text for data viz <https://medium.com/nightingale/writing-alt-text-for-data-visualization-2a218ef43f81>`_
+  * `general alt text guide <https://webaim.org/techniques/alttext/>`_
+
+* Warn on bright, strobing, images & turn off autoplay if possible.
+* For images and videos made by the social media team:
+
+  * Make graphic perceivable to people who cannot perceive color well due to
+    color-blindness, low vision, or any other reason.
+
+  * Do not make bright, strobing images.
+  * More guidelines at https://webaim.org/techniques/images/.
+
+
+Social media
+============
+
+Please follow these guidelines to maintain a consistent brand identity across
+platforms.
+
+Persona
+-------
+On social media, Matplotlib:
+
+* Acts as a sentient visualization library, so talks about itself as a we, us,
+  our, and it. Avoids talking about itself in the 3rd person. Never uses 1st person.
+* Is very earnest, eager to please, and aims to be patient & painfully oblivious
+  to snark and sarcasm.
+* Gets over-excited over shiny visualizations - lots of emojis and the like -
+  and encourages folks to share their work.
+* Highlights various parts of the library, especially the more obscure bits and
+  bobbles.
+* Acknowledges that it is a sometimes frustrating tangle of bits & bobbles that
+  can confuse even the folks who work on it & signal boosts their confuzzlment.
+
+
+Behavior
+--------
+When acting as a representative of the library, keep responses polite and assume
+user statements are in good faith unless they violate the :ref:`code of conduct <code_of_conduct>`.
+
+Social graph
+------------
+
+Only follow **organizations and projects**, do not follow individual accounts for
+any reason, even maintainers/project leads/famous Python people!
+
+Following these types of accounts is encouraged:
+
+* NumFocus and Scientific Python projects
+* 3rd party packages
+* Visualization related projects and organizations
+* Open Source community projects
+* Sponsors
+
+Recurring campaigns
+-------------------
+
+Typically the social media accounts will promote the following:
+
+* Matplotlib releases:
+
+  * Highlight new features & major deprecations
+  * Link to download/install instructions
+  * Ask folks to try it out.
+
+* `third party packages <https://matplotlib.org/mpl-third-party/>`_
+* NumFocus/Scientific Python/open source visualization project releases
+* GSOC/GSOD recruiting and progress
+
+Retired campaigns
+^^^^^^^^^^^^^^^^^
+* John Hunter Excellence in Plotting, submission and winners
+
+
+Changing the guidelines
+=======================
+
+As the person tasked with implementing communications, the `community-manager`_
+should be alerted to proposed changes to the communications guidelines. Similarly,
+specific platform guidelines (e.g. twitter, instagram) should be reviewed by the
+person responsible for that platform, when different from the community manager.
+If there is no consensus, decisions about communications guidelines revert to
+the community manager.
