 		[SceneTreeTween] is a tween managed by the scene tree. As opposed to [Tween], it does not require the instantiation of a node.
 		[SceneTreeTween]s are more light-weight than [AnimationPlayer], so they are very much suited for simple animations or general tasks that don't require visual tweaking provided by the editor. They can be used in a fire-and-forget manner for some logic that normally would be done by code. You can e.g. make something shoot periodically by using a looped [CallbackTweener] with a delay.
 		A [SceneTreeTween] can be created by using either [method SceneTree.create_tween] or [method Node.create_tween]. [SceneTreeTween]s created manually (i.e. by using [code]Tween.new()[/code]) are invalid. They can't be used for tweening values, but you can do manual interpolation with [method interpolate_value].
-		A [SceneTreeTween] animation is composed of a sequence of [Tweener]s, which by default are executed one after another. You can create a sequence by appending [Tweener]s to the [SceneTreeTween]. Animating something with a [Tweener] is called tweening. Example tweening sequence looks like this:
+		A tween animation is created by adding [Tweener]s to the [SceneTreeTween] object, using [method tween_property], [method tween_interval], [method tween_callback] or [method tween_method]:
 		[codeblock]
 		var tween = get_tree().create_tween()
 		tween.tween_property($Sprite, "modulate", Color.red, 1)
 		tween.tween_property($Sprite, "scale", Vector2(), 1)
 		tween.tween_callback($Sprite, "queue_free")
 		[/codeblock]
-		This sequence will make the [code]$Sprite[/code] node turn red, then shrink and finally the [method Node.queue_free] is called to remove the sprite. See methods [method tween_property], [method tween_interval], [method tween_callback] and [method tween_method] for more usage information.
-		When a [Tweener] is created with one of the [code]tween_*[/code] methods, a chained method call can be used to tweak the properties of this [Tweener]. For example, if you want to set different transition type in the above example, you can do:
+		This sequence will make the [code]$Sprite[/code] node turn red, then shrink, before finally calling [method Node.queue_free] to free the sprite. [Tweener]s are executed one after another by default. This behavior can be changed using [method parallel] and [method set_parallel].
+		When a [Tweener] is created with one of the [code]tween_*[/code] methods, a chained method call can be used to tweak the properties of this [Tweener]. For example, if you want to set a different transition type in the above example, you can use [method set_trans]:
 		[codeblock]
 		var tween = get_tree().create_tween()
 		tween.tween_property($Sprite, "modulate", Color.red, 1).set_trans(Tween.TRANS_SINE)
 		tween.tween_property($Sprite, "scale", Vector2(), 1).set_trans(Tween.TRANS_BOUNCE)
 		tween.tween_callback($Sprite, "queue_free")
 		[/codeblock]
-		Most of the [SceneTreeTween] methods can be chained this way too. In this example the [SceneTreeTween] is bound and have set a default transition:
+		Most of the [SceneTreeTween] methods can be chained this way too. In the following example the [SceneTreeTween] is bound to the running script's node and a default transition is set for its [Tweener]s:
 		[codeblock]
 		var tween = get_tree().create_tween().bind_node(self).set_trans(Tween.TRANS_ELASTIC)
 		tween.tween_property($Sprite, "modulate", Color.red, 1)
 		tween.tween_property($Sprite, "scale", Vector2(), 1)
 		tween.tween_callback($Sprite, "queue_free")
 		[/codeblock]
-		Another interesting use for [SceneTreeTween]s is animating arbitrary set of objects:
+		Another interesting use for [SceneTreeTween]s is animating arbitrary sets of objects:
 		[codeblock]
 		var tween = create_tween()
 		for sprite in get_children():
-		    tween.tween_property(sprite, "position", Vector2(), 1)
+		    tween.tween_property(sprite, "position", Vector2(0, 0), 1)
 		[/codeblock]
 		In the example above, all children of a node are moved one after another to position (0, 0).
-		Some [Tweener]s use transitions and eases. The first accepts an [enum Tween.TransitionType] constant, and refers to the way the timing of the animation is handled (see [url=https://easings.net/]easings.net[/url] for some examples). The second accepts an [enum Tween.EaseType] constant, and controls where the [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 [enum Tween.TransitionType] constants with [constant Tween.EASE_IN_OUT], and use the one that looks best.
