title: Using Gulp to Compile Sass and minify vendor css
body: <p>Getting to grips with Gulp and have a question.</p>
  
  <p>So I have a gulp CSS task like the below which works just fine:</p>
  
  <pre><code>var sassDir = 'app/scss';
  var targetCssDir = 'public/assets';
  
  gulp.task('css', function(){
      return gulp.src(sassDir + '/main.scss')
          .pipe(sass({ style: 'compressed' }).on('error', gutil.log))
          .pipe(autoprefix('last 10 version'))
          .pipe(gulp.dest(targetCssDir));;
  });
  </code></pre>
  
  <p>But is there a way to add my vendor files like Bootstrap so it will be included for minification and concatenation.</p>
  
  <p>Hope you can advise.!</p>
