+# Sharing project news
+
+The project aims to make it easy
+to share project news with those who publish newsletters
+that cover Node.js.
+
+The project's approach is as follows:
+
+* The project will create one "What's new in YYYY" discussion item in
+  the `nodejs/node` repo for news related to Node.js core.
+* Teams/groups can create a "what's new in YYYY" issue or discussion item
+  in one or more of their repositories. As an example see
+  [What's new in the Node-API and node-addon-api world? - 2023 version](https://github.com/nodejs/abi-stable-node/issues/446).
+* Collaborators periodically add news as additional comments on these
+  issues throughout the year.
+* At the end of each year the issue is closed and if appropriate a
+  new one is created.
+* A list of these documents is maintained in the section below as a
+  quick way to find them.
+* The next-10 team reaches out to teams/groups on an ad hoc basis
+  to ensure teams know about the option for sharing news.
+* The next-10 team reaches out to those who publish newsletters ad hoc
+  to let them know about this approach and how they can find the updates.
+
+We trust/expect collaborators to post project related news versus news
+that promotes a specific company or commercial interest.
