 # Multiple receive
 
-The multiple receive action enables receiving messages from multiple workers, waiting until a message is available from each worker to construct a record with received values.
+The multiple receive action can be used to receive values from multiple send actions. It operates by awaiting the receipt of values from all the send actions, subsequently constructing a map containing those values.
