+### Recurring Monthly Livestreams
+
+As part of our ongoing community engagement strategy, we are launching a
+**recurring monthly livestream** on the Node.js
+[YouTube channel](https://www.youtube.com/@nodejs-foundation).
+This livestream will occur around every new major release and
+serve the following purposes:
+
+* **Break down new features**: What’s new, how to use it, and how to give feedback.
+* **Contributor highlights**: Interviews with contributors and deep dives into features they’ve worked on.
+* **Live tutorials**: Hands-on demonstrations of new features with calls for community feedback.
+
+### Host & Promotion
+
+Each livestream will be promoted with a structured social media campaign, including:
+
+* **Scheduling the event** no later than 2 weeks in advance.
+* **Social media reminders** posted:
+
+  * 2 weeks before the event
+  * 1 week before the event
+  * 1 day before the event
+  * 1 hour before the event
+
+All posts will be prepared in advance on a Pull Request in the
+[Node.js ambassadors repo](https://github.com/nodejs/nodejs-ambassadors) and
+shared for approval and scheduling.
