It’s a gathering of state delegates that consider, then vote on, then propose amendment or amendments to the US Constitution. This amendment or amendments are then sent to the states for ratification. The states have to ratify just like in the past, it does not directly change the Constitution. It bypasses Congress drawing up and passing an amendment or amendments to be submitted to the states. See Article V US Constitution.
