npm install laravel-elixir-hbsfy

Within your main Gulpfile, add:

var elixir = require('laravel-elixir');

require('laravel-elixir-hbsfy');

elixir(function(mix) {
    mix.browserify('main.js');
});

Notice above, where we require laravel-elixir-hbsfy. That's all you need. Behind the scenes, all of the necessary dependencies have been installed, and Hbsfy has been inserted into Laravel Elixir's Browserify transformers list.

You're done. :)
