 Echo comes with basic implementations of common math structures (Vector2, Vector3, Matrix3), but also allows these structures to be extended and used seamlessly with other popular Haxe math libraries. 
 
-Support is currently available for [hxmath](https://github.com/tbrosman/hxmath), [vector-math](https://github.com/haxiomic/vector-math), and [zerolib](https://github.com/01010111/zerolib).
+Support is currently available for the following libraries (activated by adding the listed compiler flag to your project's build parameters):
+
+| Library | Compiler Flag |
+| --- | --- |
+| [hxmath](https://github.com/tbrosman/hxmath) | ECHO_USE_HXMATH |
+| [vector-math](https://github.com/haxiomic/vector-math) | ECHO_USE_VECTORMATH |
+| [zerolib](https://github.com/01010111/zerolib) | ECHO_USE_ZEROLIB |
+| [heaps](https://heaps.io) | ECHO_USE_HEAPS |
 
 (pull requests for other libraries happily accepted!)
 
-If you compile your project with a standard `.hxml`, add one of these to your file:
+If you compile your project with a standard `.hxml`:

 For OpenFL users, add one of the following into your `Project.xml`:
 ```xml
 <!-- hxmath support -->
 <haxelib name="hxmath" />

 ```
 
 For Kha users, add one of the following into your `khafile.js`:
 ```js
 // hxmath support
 project.addLibrary('hxmath');
 project.addDefine('ECHO_USE_HXMATH');
