+Experimental fork of [ng-annotate](https://github.com/olov/ng-annotate).  Adds Angular 1.x DI annotations to ES5/ES6 code being processed by babel, with support for explicit annotations (`/* @ngInject */`) and implicit annotations of idiomatic Angular code.

+
+This plugin currently supports matching and transforming all of the patterns currently recognized by ng-annotate (explicit and implicit), and passes the relevant portions of ng-annotate's test suite.  ES6 support will be expanded in future releases -- contributions are welcome!

+See [ng-annotate](https://github.com/olov/ng-annotate)'s documentation for more details.

+## Usage
+
+Use like any other [Babel plugin](https://babeljs.io/docs/plugins/).  
+
+Most users will want to run 
+
+```sh
+$ npm install babel-plugin-angularjs-annotate --save-dev
+```
+
+and add the plugin to your `.babelrc` file:
+
+```json
+{
+  "presets": ["es2015"],
+  "plugins": ["path/to/babel-ng-annotate"]

 * ✓ Support the majority of invocations/annotations currently performed by ng-annotate
 * ✓ Split up ng-annotate's test suite to be more granular and tolerant of some of babel's other transforms.
