Prior to Polymer 1.0, I was using python simple http server and/or apache. When I came across the starter kit app, I started using the built in browsersync, through gulp serve.

Is that appropriate for hosting on Heroku? 

I added:

```
"scripts": {
  "start": "gulp serve:dist"
},

```

to my package.json, and it attempts to run. When I try to load the page, I get:

```
heroku[router]: at=error code=H10 desc="App crashed" method=GET

```

Heroku's guides are based on traditional node apps, and the Procfile or "script" in package.json, is typically just `node app.js`. 

I feel like I'm missing something trivial. Any help would be greatly appreciated!
