+## Fortnightly coreboot leadership meeting
+
+There's a leadership meeting held every 14 days (currently every other
+Wednesday at 10am Pacific Time, usually 18:00 UTC with some deviation
+possible due to daylight saving time related shifts). The meeting
+is open to everyone and provides a forum to discuss general coreboot
+topics, including community and technical matters that benefit from
+an official decision.
+
+We tried a whole lot of different tools, but so far the meetings worked
+best with [Google Meet](https://meet.google.com/syn-toap-agu),
+using [Google Docs](https://docs.google.com/document/d/1NRXqXcLBp5pFkHiJbrLdv3Spqh1Hu086HYkKrgKjeDQ/edit)
+for the agenda and meeting minutes. Neither the video conference nor
+the document require a Google account to participate, although editing
+access to the document is limited to adding comments - any desired
+agenda item added that way will be approved in time before the meeting.
