Learn how to deploy Bridgetown apps with Hatchbox

Bridgetown is an app builder in Ruby.

When Hatchbox detects `bridgetown` in the Gemfile.lock, it will trigger the build:

```
bin/bridgetown deploy
mv output public
```

Hatchbox will also automatically set `BRIDGETOWN_ENV=production` on the first deploy.

If you're using the Puma functionality with Bridgetown, we'll also automatically add a Puma process to the application so it can handle requests.
