+# Data Inheritance Plugin for Pattern Lab
+
+The Data Inheritance Plugin forces patterns to inherit data from their lineage. This allows data in included patterns to bubble
+to the top of the pattern stack. With this plugin pseudo-patterns become first-class citizens.
+
+This is a crap intro. Rewrite it.
+
+## Installation
+
+To add the Data Inheritance Plugin to your project using [Composer](https://getcomposer.org/) type:
+
+    composer require pattern-lab/plugin-data-inheritance
+
+See Packagist for [information on the latest release](https://packagist.org/packages/pattern-lab/plugin-data-inheritance).
+
+## Usage
+
+After install make sure to generate your site again with:
+
+    php core/console --generate
+
+
+## Disabling the Plugin
+
+To disable the Faker plugin you can either directly edit `./config/config.yml` or use the command line option:
+
+    php core/console --config --set plugins.dataInheritance.enabled=false
