+GTween is a small but extremely robust [Haxe](https://haxe.org/) library for programmatic tweening, animation, and transitions. It is based on the AS3 library for Adobe Flash built by Grant Skinner of _gskinner.com_.
+
+The GTween library is currently comprised of 3 key classes:
 
 * **GTween**. A robust tweening engine, packed full of innovative features.
 * **GTweenTimeline**. A powerful virtual timeline that extends GTween to enable you to sequence tweens and actions.
 * **GTweener**. A static interface to GTween.

+GTween also comes with a variety of plug-ins and easing classes to customize your animations.
+
+The Haxe version of GTween is designed to be added to _any_ Haxe project, not just those that depend on libraries like OpenFL that provide an Adobe Flash-inspired API. A subset of GTween's plugins are restricted to OpenFL features only, but the core library is written in pure Haxe and can absolutely be used without OpenFL as a dependency.
 
 GTween is licensed under the **MIT license**, so it can be used and modified with **almost no restrictions in commercial projects** beyond maintaining the header in the source files.

 GTweenTimeline lets you set up complex animations or transitions on a **virtual timeline**.
 In addition to tweens, you can add actions and labels at specified positions.
 Pause, reverse, and jump to the start or end of the full timeline as easily as you would with a single tween.
