 # Smart Doors
-Sends a message to chat when a player tries to open a locked door
+Makes doors smarter. Allows doors to synchronize across multiple scenes and sends chat messages when players try to open locked doors (and also tells you which of the doors).
 
 ## Planned features
 - Attach macros to doors that are being executed when the door is being opened/closed
-- Synchronize the opening/closing of doors
 - Give out keys to players, that allow them to lock/unlock associated doors
