+Grunt CSS-PURGE
 ===============
 
-> Grunt plugin to run [CSS-Purge](https://github.com/rbtech/css-purge)
+Purges duplicate CSS rules and more. Based on [css-purge](https://www.npmjs.org/package/css-purge).
 
-[![NPM](https://nodei.co/npm/grunt-css-purge.png)](https://nodei.co/npm/grunt-css-purge/)
 
-## Getting Started
-This plugin requires Grunt.
+## You have an issue?
+
+This is a simple [grunt](http://gruntjs.com/) plugin, which means it’s a thin wrapper around `css-purge`. If you are having CSS issues, please
+contact [css-purge](https://github.com/rbtech/css-purge/issues). Please only create a new issue if it looks like you’re having a problem with the grunt plugin.
 
-If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide,
-as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar
-with that process, you may install this plugin with this command:
 
-```shell
+## Install
+
+```
 npm install grunt-css-purge --save-dev
 ```
 
+
+## Options
+
+Visit the [CSS-PURGE website](http://rbtech.github.io/css-purge)
+
+
+## Getting Started

 Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
 
 ```js
 grunt.loadNpmTasks('grunt-css-purge');
 ```
 
-## The "css_purge" task
 
-### Overview
-In your project's Gruntfile, add a section named `css_purge` to the data object passed into `grunt.initConfig()`.
+## Example use cases
+
+The most basic `Gruntfile.js` setup:
 
 ```js
-grunt.initConfig({
-css_purge: {
-options: {
-"verbose": false,
-"no_duplicate_property": true,
-},
-files: {
-'purged.css': 'bigFile.css',
+'use strict';
+
+module.exports = function( grunt ) {
+grunt.loadNpmTasks('grunt-css-purge');
+
+grunt.initConfig({
+css_purge: {
+site: {
+options: {},
+src: 'site.css',
+dest: 'site.min.css',
+},
 },
-},
-})
+});
+
+grunt.registerTask('default', ['css_purge']);
+};
 ```
 
-### Options
+For more infos about the options please look at the [CSS-Purge website](http://rbtech.github.io/css-purge/).
 
-#### options.verbose
-Type: `Boolen`
-Default value: `false`

-#### options.no_duplicate_property
-Type: `Boolen`
-Default value: `true`
+```js
+default_options: {
+options: {},
+src: 'site.css',
+dest: 'site.min.css',
+},
+```
 
-Allow duplicate properties on a selector
+Multiple files:
 
-### Usage Examples
+```js
+multiple_files: {
+options: {},
+src: [
+'site1.css',
+'site2.css',
+],
+dest: 'site.min.css',
+},
+```
 
-#### Default Options
+Multiple files:
 
 ```js
-css_purge: {
+multiple_files2: {
+options: {},
 files: {
-'purged.css': 'bigFile.css',
+'site.min.css': ['site1.css', 'site2.css'],
 },
 },
 ```
 
-#### Custom Options
+Multiple files with a wildcard:
 
 ```js
-css_purge: {
+multiple_files3: {
+options: {},
+files: [{
+src: ['css/**/*.css'],
+dest: 'site.min.css',
+}],
+},
+```
+
