+## Bundle
+
+The [FullCalendar Standard Bundle](bundle) is easier to install than individual plugins, though filesize will be larger. It works well with a CDN.
+
+## Installation
+
+Install the FullCalendar core package and any plugins you plan to use:
+
+```sh
+npm install @fullcalendar/core @fullcalendar/interaction @fullcalendar/daygrid
+```
+
+## Usage
+
+Instantiate a Calendar with plugins and options:
+
+```js
+import { Calendar } from '@fullcalendar/core'
+import interactionPlugin from '@fullcalendar/interaction'
+import dayGridPlugin from '@fullcalendar/daygrid'
+
+const calendarEl = document.getElementById('calendar')
+const calendar = new Calendar(calendarEl, {
+  plugins: [
+    interactionPlugin,
+    dayGridPlugin
+  ],
+  initialView: 'timeGridWeek',
+  editable: true,
+  events: [
+    { title: 'Meeting', start: new Date() }
+  ]
+})
+
+calendar.render()
+```
+
+## Development
+
+You must install this repo with [PNPM](https://pnpm.io/):
+
+```
+pnpm install
+```
+
+Available scripts (via `pnpm run <script>`):
+
+- `build` - build production-ready dist files
+- `dev` - build & watch development dist files
+- `test` - test headlessly
+- `test:dev` - test interactively
+- `lint`
+- `clean`
