The package can be installed via npm:

npm i gestalt --save
npm i gestalt-datepicker --save

Or via yarn:

yarn add gestalt
yarn add gestalt-datepicker

Gestalt DatePicker exports each component as ES6 modules and a single, precompiled CSS file:

import { DatePicker } from 'gestalt-datepicker';
import 'gestalt-datepicker/dist/gestalt-datepicker.css';
