+				The [code]arrays[/code] argument is an array of arrays. See [enum ArrayType] for the values used in this array. For example, [code]arrays[0][/code] is the array of vertices. That first vertex sub-array is always required; the others are optional. Adding an index array puts this function into "index mode" where the vertex and other arrays become the sources of data and the index array defines the vertex order. All sub-arrays must have the same length as the vertex array or be empty, except for [code]ARRAY_INDEX[/code] if it is used.

 	<description>
-		Node useful for animations with unknown start and end points, procedural animations, making one node follow another, and other simple behavior.
-		Because it is easy to get it wrong, here is a quick usage example:
+		Tweens are useful for animations requiring a numerical property to be interpolated over a range of values. The name *tween* comes from *in-betweening*, an animation technique where you specify *keyframes* and the computer interpolates the frames that appear between them.
+		Here is a brief usage example that causes a 2D node to move smoothly between two positions:
 		[codeblock]
 		var tween = get_node("Tween")
-		tween.interpolate_property(get_node("Node2D_to_move"), "transform/origin", Vector2(0,0), Vector2(100,100), 1, Tween.TRANS_LINEAR, Tween.EASE_IN_OUT)
+		tween.interpolate_property($Node2D, "position",
+                Vector2(0, 0), Vector2(100, 100), 1,
+                Tween.TRANS_LINEAR, Tween.EASE_IN_OUT)
 		tween.start()
 		[/codeblock]
-		Some of the methods of this class require a property name. You can get the property name by hovering over the property in the inspector of the editor.
-		Many of the methods accept [code]trans_type[/code] and [code]ease_type[/code]. The first accepts an TRANS_* constant, and refers to the way the timing of the animation is handled (you might want to see [code]http://easings.net/[/code] for some examples). The second accepts an EASE_* constant, and controls the where [code]trans_type[/code] is applied to the interpolation (in the beginning, the end, or both). If you don't know which transition and easing to pick, you can try different TRANS_* constants with EASE_IN_OUT, and use the one that looks best.
+		Many methods require a property name, such as "position" above. You can find the correct property name by hovering over the property in the Inspector.
