# Firebase

Connect Firebase so your app can receive push notifications.

Push notifications reach phones through Google's Firebase. Before you can send anything, your app needs its own Firebase project and the config files that connect the two.

This is a one-time setup. Once it is done, every campaign in [Engage](/push/overview.md) works.

<table data-view="cards"><thead><tr><th></th><th></th><th data-hidden data-card-target data-type="content-ref"></th></tr></thead><tbody><tr><td><strong>Enable Push Notification</strong></td><td>Create your Firebase project, upload the config files, and turn push on.</td><td><a href="/push/firebase-push-notification/enable-push-notification.md">Enable Push Notification</a></td></tr></tbody></table>

Once push is on, decide what to send — see [Overview](/push/overview.md).
