  * @classdesc
  * A Frame based Animation.

- * This consists of a key, some default values (like the frame rate) and a bunch of Frame objects.
+ * Animations in Phaser consist of a sequence of `AnimationFrame` objects, which are managed by
+ * this class, along with properties that impact playback, such as the animations frame rate
+ * or delay.
  *
- * The Animation Manager creates these. Game Objects don't own an instance of these directly.
- * Game Objects have the Animation Component, which are like playheads to global Animations (these objects)
- * So multiple Game Objects can have playheads all pointing to this one Animation instance.
+ * This class contains all of the properties and methods needed to handle playback of the animation
+ * directly to an `AnimationState` instance, which is owned by a Sprite, or similar Game Object.
+ *
+ * You don't typically create an instance of this class directly, but instead go via
+ * either the `AnimationManager` or the `AnimationState` and use their `create` methods,
+ * depending on if you need a global animation, or local to a specific Sprite.
