-		Class representing a signal defined in an object.
+		Built-in type representing a signal defined in an object.
 	</brief_description>
 	<description>
-		Signals can be connected to [Callable]s and emitted. When a signal is emitted, all connected callables are called.
-		Usually signals are accessed as properties of objects, but it's also possible to assign them to variables and pass them around, allowing for more dynamic connections.
+		[Signal] is a built-in [Variant] type that represents a signal of an [Object] instance. Like all [Variant] types, it can be stored in variables and passed to functions. Signals allow all connected [Callable]s (and by extension their respective objects) to listen and react to events, without directly referencing one another. This keeps the code flexible and easier to manage.
+		In GDScript, signals can be declared with the [code]signal[/code] keyword. In C#, you may use the [code][Signal][/code] attribute on a delegate.

+		# These arguments must be passed when the signal is emitted.
