-## Dependencies
-
-The Calendar component uses the experimental [`Temporal` API](https://tc39.es/proposal-temporal/docs/) which has reached [stage 3](https://github.com/tc39/proposals#stage-3) in the [ECMAScript proposal](https://github.com/tc39/proposal-temporal) process but isn't implemented in [most browsers](https://caniuse.com/temporal) yet. Circuit UI depends on a [polyfill](https://github.com/fullcalendar/temporal-polyfill) which you need to install to use the component in your application:
-
-```bash
-# npm
-npm install temporal-polyfill
-# yarn v1
-yarn add temporal-polyfill
-```
