1. Install gulp globally

$npm install --global gulp

2. Install gulp in project devDependencies

$npm install --save-dev gulp

3. Create a gulpfile.js
at the root of project

var gulp = require('gulp');

gulp.task('default', function() {
  console.log('this is the default task');
});

4. Run gulp

$gulp

(outputs):
'this is the default task'

How it helps

1. HTML Injection
2. Keeping your browser in sync
3. Building and organizing assets
4. Caching HTML templates
5. Creating a production build
6. Minification and filtering
7. Angular Dependency Injection
8. Static asset revisions
9. Unit Testing
10. Integration testing

gulp.task(name, [, dep], fn)

gulp.task('js', ['jscs', 'jshint'], function() {
  return gulp
      .src('./src/**/*.js')
      .pipe(concat('all.js')
      .pipe(uglify())
      .pipe(gulp.dest('./build/'));
});

Dependency tasks run in parallel, not in sequence
