Dx12 - timestamp queries

Hi all, Any idea what the mechanism is for timing commands in the GPU command buffer in DX12 now? In DX11 it was BeginDisjoint, End's, EndDisjoint, GetData's. But in DX12, I see I can place EndQuery with a timestamp type, and I also see GetTimestampFrequency to get the frequency, but how do I get the tick value for each of the timestamp EndQuery's? I see ResolveQueryData, but that places the data in a GPU buffer, am I supposed to call that and then copy the data over? If so what is the format of that data? Unfortunately, I have yet to see a sample for timestamp queries yet. Thanks!
