+#Angular-DragDrop
+[![Build status](http://img.shields.io/travis/angular-dragdrop/angular-dragdrop.svg?style=flat)](https://travis-ci.org/angular-dragdrop/angular-dragdrop)
+[![Gitter](https://badges.gitter.im/Join Chat.svg)](https://gitter.im/ganarajpr/angular-dragdrop?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge)
+
+Angular-DragDrop is a angular HTML5 Drag and Drop directive written in pure with no dependency on JQuery.
+
+This is based on the work done by Jason Turim. While this [blog post](http://jasonturim.wordpress.com/2013/09/01/angularjs-drag-and-drop/) was the inspiration for creating a native Drag and Drop solution, the intention was to create something that was more generic. 
+
+This implementation is mainly different from the one posted in the blog in the following areas : 
+
+1. Angular-DragDrop does not create an isolate scope. This has huge benefits when it comes to working with other directives. **NOTE :** It also does not pollute the scope with any variables or functions.
+
+2. It does not depend on any kind of an ID attribute ( being either present or generated on the fly ). 
+
+3. It allows one to create channels on which different drag and drop directive combinations can work on in the same page ( more on this later ) . 
+
+Pull requests are welcome.
