# PACKAGE_JSON_DESCRIPTION_REQUIRED

This check ensures that every `package.json` has a `description` field.
This field is used to describe the workspace's purpose within the monorepo.

See the [Node.js docs](https://nodejs.org/api/packages.html#description) for more information.

## How to fix

Add the `description` field to the `package.json` file that explains
