Get Started with Firebase App Check
2+
===================================
3+
4+
Thank you for installing the Firebase App Check Unity SDK. App Check
5+
is intended to be used in conjunction with other Firebase products:
6+
7+
* [Cloud Firestore](https://firebase.google.com/products/firestore/)
8+
* [Cloud Functions for Firebase](https://firebase.google.com/products/functions/)
9+
* [Firebase Realtime Database](https://firebase.google.com/products/realtime-database/)
10+
* [Firebase Remote Config](https://firebase.google.com/products/remote-config/)
11+
12+
# Overview
13+
14+
[Firebase App Check](https://firebase.google.com/docs/app-check/)
15+
helps protect your API resources from abuse by preventing unauthorized clients
16+
from accessing your backend resources. It works with both Firebase services,
17+
Google Cloud services, and your own APIs to keep your resources safe.
