How it Works
------------
Here's a high-level overview of how this buildpack works:
Here's an overview of what this buildpack does:
- Uses the [semver.io](http://semver.io) webservice to find the latest version of node that satisfies the [engines.node semver range](https://npmjs.org/doc/json.html#engines) in your package.json.
- Allows any recent version of node to be used, including [pre-release versions](http://semver.io/node.json).

For most Node.js apps this buildpack should work just fine. If, however, you're unable to deploy using this new version of the buildpack, you can get your app working again by using the legacy branch:
```
heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs#legacy -a my-app
git commit -am "empty" --allow-empty # force a git commit
git push heroku master
```
Then please open a support ticket at [help.heroku.com](https://help.heroku.com/) so we can diagnose and get your app running on the default buildpack.
