-## Use Cases
-
-There are two environments in which [ZEIT](https://zeit.co) uses this package:
-
-### Production
-
-When deploying your static project to [Now](https://zeit.co/now), you can add any of the [configuration options](https://github.com/zeit/serve-handler#options) to the `static` property within `now.json` and they will be considered when handling requests to your deployment.
-
-### Development
-
-When testing your project on your local device, we suggest using [serve](https://github.com/zeit/serve).
-
-Since it comes with support for `serve-handler` out of the box, you can create a `serve.json` file to customize its behavior. It will also read the configuration from `static` inside `now.json`.
