My Gruntfile which does every thing for me

Gruntjs

/*global module:false*/
module.exports = function (grunt) {
  require('jit-grunt')(grunt);

  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    banner: '/*! <%= pkg.title || pkg.name %> - v<%= pkg.version %> - ' 
    + '<%= grunt.template.today("yyyy-mm-dd") %>\n'
    + '<%= pkg.homepage ? "* " + pkg.homepage + "\\n" : "" %>'
    + '* Copyright (c) <%= grunt.template.today("yyyy") %> <%= pkg.author.name %>;'
    + ' Licensed <%= _.pluck(pkg.licenses, "type").join(", ") %> */\n',
  });

  require('time-grunt')(grunt);
  require('load-grunt-config')(grunt);

  grunt.registerTask('default', [
    'newer:browserify',
    'jshint', 
    'newer:concat', 
    'newer:uglify', 
    'newer:less', 
    'newer:cssmin', 
    'newer:copy'
    ]);
  grunt.registerTask('build', ['newer:copy:build']);
};
