CHANGELOG

 THIS CHANGELOG IS AN ATTEMPT TO DOCUMENT CHANGES TO THIS PROJECT.
+PL-node-v0.10.0
+ - ADD: Added support for pattern parameters! Resolves #88
+ - FIX: Data inheritance is now working as advertised. Resolves #127. This turned out to be a MAJOR thing, as I realized the home-page was not passing down any of its json data to partials.
+ - CHG: Refactored a lot of code out of patternlab.js and into separate files. Doing so should make everything dryer, more unit testable, and easier to understand I hope.
+ - ADD: Added proper styling for the homepage-emergency alert that is displayed for demo purposes
+ - ADD: Added a new comment organism, the sticky comment, to ship an example of pattern parameters
+ - CHG: Start some JS linting of the project. I don't quite agree with a lot of it, so am trying to set some smart configurations
+ - CHG: wrapped some build messages in the patternlab.config.debug flag

 ## About the Node Version of Pattern Lab
 
 The Node version of Pattern Lab is, at its core, a static site generator. It combines platform-agnostic assets, like the [Mustache](http://mustache.github.io/)-based patterns and the JavaScript-based viewer, with a Node-based "builder" that transforms and dynamically builds the Pattern Lab site. By making it a static site generator, the Node version of Pattern Lab strongly separates patterns, data, and presentation from build logic. The Node version is a work in progress, the [PHP version](https://github.com/pattern-lab/patternlab-php) should be seen as a reference for other developers to improve upon as they build their own Pattern Lab Builders in their language of choice.

+##### Pattern Parameters
+attern parameters are a simple mechanism for replacing Mustache variables via attributes on a pattern partial tag rather than having to use a pattern-specific json file. They are especially useful when you want to supply distinct values for Mustache variables in a specific pattern partial instance that may be included multiple times in a molecule, template, or page.
+
+The basic syntax is this:
+
+```
+{{> molecules-single-comment(description: 'A life is like a garden. Perfect moments can be had, but not preserved, except in memory.') }}
+```
+
+The attributes listed in the pattern parameters should match Mustache variable names in your pattern. The values listed for each attribute will replace the Mustache variables. Again, pattern parameters are a simple find and replace of Mustache variables with the supplied values.
+
+Pattern parameters **do not** currently support the following:
+
+* sub-lists (e.g. iteration of a section),
+* and the use of long strings of text can be unwieldy
+* nested properties within the parameter data, such as `{{> molecules-single-comment(foo.bar: 'baz') }}`
+
+You can read the full documentation on pattern parameters here: [Using Pattern Parameters](http://patternlab.io/docs/pattern-parameters.html)
+
 ##### Pseudo-Patterns
 Pseudo-patterns are meant to give developers the ability to build multiple and unique **rendered** patterns off of one base pattern and its mark-up while giving them control over the data that is injected into the base pattern. This feature is especially useful when developing template- and page-style patterns.
