Improve Documentation

[NoelBroda]

Please, guys, improve documentation. I want to do something easy like "serve the path xxx/xxx/xxx" and I can't found an example.

This is not working:

gulp.task('webserver', function() {
  gulp.src('app')
    .pipe(webserver({
      livereload: true,
      directoryListing: true,
      open: true,
     path: '/xxx/xxx/xxx'
    }));
});
