+# grunt-open
+
+Open urls and files from a grunt task
+
+## Installation
+
+Install alongside your Gruntfile
+
+```bash
+$ npm install --save grunt-open
+```
+
+## Usage
+
+This is immediately useful as part of your task chain between `server` and `watch`
+
+```js
+grunt.registerTask('default', 'server open watch');
+```
+
+You can specify different configurations so that you can set up task chains like
+
+```js
+grunt.registerTask('dev', 'server open:dev watch');
+grunt.registerTask('dev', 'build server open:build watch:build');
+```
+
+## Getting Started
+Install this grunt plugin next to your project's [Gruntfile][getting_started] with: `npm install grunt-open`
+
+## Configuration
+
+This is a very simple task and takes only one configuration parameter, `path`.
+
+```js
+grunt.initConfig({
+  open : {
+    dev : {
+      path: 'http://127.0.0.1:8888/src'
+    },
+    google : {
+      path : 'http://google.com/'
+    },
+    file : {
+      path : '/etc/hosts'
+    }
+  }
+})
+
+grunt.loadNpmTasks('grunt-open');
+
+```
