Jade Support for Yeoman

yeoman-jade

Install grunt-contrib-jade
  (sudo) npm install grunt-contrib-jade --save-dev

Create the JADE Task:

    jade: {
      dist: {
        options: {
            pretty: true
        },
        files: [{
            expand: true,
            cwd: '<%= yeoman.app %>',
            dest: '<%= yeoman.app %>', //Keep the dest in the same place
            src: ['**/*.jade'], //This holds the folder structure
            ext: '.html'
        }]
      }
    },

Add to the watch task:
      jade: {
        files: ['<%= yeoman.app %>/{,*/}*.jade'],
        tasks: ['jade']
      },

Add it to the other grunt tasks at the end

    grunt.task.run([
      'clean:server',
      'jade',
      'concurrent:server',
      'connect:livereload',
      'open',
      'watch'
    ]);
  });

  grunt.registerTask('build', [
    'clean:dist',
    'jade',
    'useminPrepare',
    'concurrent:dist',
    'concat',
    'copy',
    'cdnify',
    'ngmin',
    'cssmin',
    'uglify',
    'rev',
    'usemin'
  ]);
