+We are holding a weekly OAI Developer Call open to all OAI community members.
+
+**At the time of writing, the time slot is one hour every Tuesday, at 11AM CEST.**
+
+If anyone wants to join, please send an email to [**openair_tech@eurecom.fr**](mailto:openair_tech@eurecom.fr).
+
+As of May 2017 we decided to move the meeting minutes to a new tool called trello [OAI weekly meeting Trello board](https://trello.com/b/7kFj0kFp/oai-weekly-meetings).
+
+* Each project is a card and updates from every week are added as a comment to the card.
+* Cards also have checklists to give a high level overview of the project's progress.
+* Developers are invited to edit these checklists themselves.
+
+Let me know (@florian.kaltenberger) if you need write access to the trello.
