 ## Status
 
 You can author standalone React components that include only the main React module, which I know isn't much yet. We're working on it.
 
 The current release works with the 2.X series of Patternlab / Node. Support for the 3.X series is underway on the `dev` branch.

 ## Extensions to basic Underscore functionality
 
 ### Pattern including
 
-Underscore templates include no native support for calling other templates, so support for pattern including is accomplished through an included Underscore mixin function, [`_.renderNamedPartial()`](https://github.com/pattern-lab/patternengine-node-underscore/blob/master/lib/engine_underscore.js#L54-L59), and is considered experimental, but seems to work just fine.
