+## LEGO Hub compatibility
+
+The most well-tested hubs currently are the LEGO City hub and the LEGO Technic hub. The Mindstorms (Spike Prime) hub should also work by default, but is not tested as regularly. Unfortunately, the move hub (from LEGO Boost) is currently incompatible because of it's low memory.
