+
+> Load multiple grunt tasks using globbing patterns
+
+Usually you would have to load each task one by one, which is unnecessarily cumbersome.
+
+This module will read the `dependencies`/`devDependencies`/`peerDependencies` in your package.json and load grunt tasks that match the provided patterns.
+
+
+#### Before
+
+```js
+grunt.loadNpmTasks('grunt-shell');
+grunt.loadNpmTasks('grunt-sass');
+grunt.loadNpmTasks('grunt-recess');
+grunt.loadNpmTasks('grunt-sizediff');
+grunt.loadNpmTasks('grunt-svgmin');
+grunt.loadNpmTasks('grunt-styl');
+grunt.loadNpmTasks('grunt-php');
+grunt.loadNpmTasks('grunt-eslint');
+grunt.loadNpmTasks('grunt-concurrent');
+grunt.loadNpmTasks('grunt-bower-requirejs');
+```
+
+#### After
+
+```js
+require('load-grunt-tasks')(grunt);
+```
+
+
+## Install
+
+```
+$ npm install --save-dev load-grunt-tasks
+```
+
+
+## Usage
+
+```js
+// Gruntfile.js
+module.exports = function (grunt) {
+	// load all grunt tasks matching the ['grunt-*', '@*/grunt-*'] patterns
+	require('load-grunt-tasks')(grunt);
+
+	grunt.initConfig({});
+	grunt.registerTask('default', []);
+}
+```
+
+
+## Examples
+
+### Load all grunt tasks
+
+```js
+require('load-grunt-tasks')(grunt);
+```
+
+Equivalent to:
+
+```js
+require('load-grunt-tasks')(grunt, {pattern: ['grunt-*', '@*/grunt-*']});
+```
+
+### Load all grunt-contrib tasks
+
+```js
+require('load-grunt-tasks')(grunt, {pattern: 'grunt-contrib-*'});
+```
+
+### Load all grunt-contrib tasks and another non-contrib task
+
+```js
+require('load-grunt-tasks')(grunt, {pattern: ['grunt-contrib-*', 'grunt-shell']});
+```
+
+### Load all grunt-contrib tasks excluding one
+
+You can exclude tasks using the negate `!` globbing pattern:
+
+```js
+require('load-grunt-tasks')(grunt, {pattern: ['grunt-contrib-*', '!grunt-contrib-coffee']});
+```
+
+### Set custom path to package.json
+
+```js
+require('load-grunt-tasks')(grunt, {config: '../package'});
+```
+
+### Only load from `devDependencies`
+
+```js
+require('load-grunt-tasks')(grunt, {scope: 'devDependencies'});
+```
+
+### Only load from `devDependencies` and `dependencies`
+
+```js
+require('load-grunt-tasks')(grunt, {scope: ['devDependencies', 'dependencies']});
+```
+
+### All options in use
+
+```js
+require('load-grunt-tasks')(grunt, {
+	pattern: 'grunt-contrib-*',
+	config: '../package.json',
+	scope: 'devDependencies'
+});
+```
+
+
+## Options
+
+### pattern
+
+Type: `string`, `array`  
+Default: `['grunt-*', '@*/grunt-*']` ([globbing pattern](https://github.com/isaacs/minimatch))
+
+### config
+
+Type: `string`, `object`  
+Default: Path to nearest package.json
+
+### scope
+
+Type: `string`, `array`  
+Default: `['dependencies', 'devDependencies', 'peerDependencies']`  
+Values: `'dependencies'`, `'devDependencies'`, `'peerDependencies'`, `'bundledDependencies'`
