+The **spatialdata** developer sync is a biweekly, developer-focused meeting: a space to discuss ongoing work and onboard new contributors (no prior contribution needed).
+It runs _only when someone books it_, so it works a little differently from a fixed meeting:
+
+- If the session already shows on the calendar above, it's confirmed. Just join at that time!
+- If it's not on the calendar yet, someone needs to book an open slot below (at least 72 hours ahead) to make that session happen. Once booked, it appears on the calendar and anyone is welcome to join.
+
+So you only need to book if you want to _start_ a session that isn't scheduled yet. Booking is what turns an open slot into a real meeting everyone can join.
