1: Install gulp globally:

If you have previously installed a version of gulp globally, please run npm rm --global gulp to make sure your old version doesn’t collide with gulp-cli.

$ npm install –global gulp-cli

2:  Initialize your project directory:

$ npm init

3:  Install gulp in your project devDependencies:

$ npm install --save-dev gulp

4:   Create a gulpfile.js at the root of your project:

var gulp = require('gulp');

gulp.task('default', function() {
  // place code for your default task here
});

5. Run gulp:

$ gulp

The default task will run and do nothing.

To run individual tasks, use gulp <task> <othertask>.
