 /******************************************************************************
 	INSTRUCTIONS FOR USE:
 	On broadcaster side:
-		1. 
+		1. Create a struct/class to contain the data that you would need to send
+			 in the event.
+		2. Create unique event identifier in SHEventDefines.h, follow the example
+			 provided.
+		3. When ready to send the event, call
+			 SHEventManager::BroadcastEvent<ExampleClass>(exampleClass, EVENT_IDENTIFIER);
+
+		Headers required: SHEventManager.h
+
+	On Receiver side:
+		1. Create a function with the signature:
+			 SHEventHandle FunctionName(SHEvent);
+		2. In the init function of the class, copy the below in and replace the
+			 necessary:
+
+			 std::shared_ptr<SHEventReceiverSpec<ReceiverClass>> thisReceiver{
+				std::make_shared<SHEventReceiverSpec<ReceiverClass>>(this, &ReceiverClass::ReceiveFunction)
+			 };
+			 ReceiverPtr receiver = std::dynamic_pointer_cast<SHEventReceiver>(thisReceiver);
+			 SHEventManager::SubscribeTo(EVENT_IDENTIFIER, receiver);
+
+		3. Note: The EventIdentifier should match all that is defined in
+			 SHEventDefines.h so check there. When the receiver catches the event, it
+			 needs to know the struct that the broadcaster is using to cast the void*
+			 properly.
+
+		Headers required: SHEventManager.h, SHEventReceiver.h
