 Below is a sample implementation using Google's Identity Provider. Please note that the OAuth 2.0 request in the `refreshAccessToken()` function will vary between different providers, but the core logic should remain similar.

-## Overview
 
-This is the Firebase Adapter for [`auth.js`](https://authjs.dev). This package can only be used in conjunction with the primary `next-auth` package. It is not a standalone package.
+This is the official Firebase Adapter for [Auth.js](https://authjs.dev) / [NextAuth.js](https://next-auth.js.org/), using the [Firebase Admin SDK](https://firebase.google.com/docs/admin/setup) and [Firestore](https://firebase.google.com/docs/firestore).
 
-You can find more Firebase information in the docs at [authjs.dev/reference/adapters/firebase](https://authjs.dev/reference/adapters/firebase).
+## Documentation
 
-## Getting Started
-
-1. Install `next-auth` and `@next-auth/firebase-adapter`.
-
-```js
-npm install next-auth @next-auth/firebase-adapter
-```
-
-2. Add this adapter to your `pages/api/[...nextauth].js` next-auth configuration object.
-
-```js
-import NextAuth from "next-auth"
-import Providers from "next-auth/providers"
-import { FirestoreAdapter } from "@next-auth/firebase-adapter"
-
-import { initializeApp } from "firebase/app";
-import { getFirestore } from "firebase/firestore"
-
-const app = initializeApp({ projectId: "next-auth-test" });
-const firestore = getFirestore(app);
-
-// For more information on each option (and a full list of options) go to
-// https://authjs.dev/reference/configuration/auth-options
-export default NextAuth({
-  // https://authjs.dev/reference/providers/oauth-builtin
-  providers: [
-    Providers.Google({
-      clientId: process.env.GOOGLE_ID,
-      clientSecret: process.env.GOOGLE_SECRET,
-    }),
-  ],
-  adapter: FirestoreAdapter(firestore),
-  ...
-})
-```
-
-## Options
-
-When initializing the firestore adapter, you must pass in the firebase config object with the details from your project. More details on how to obtain that config object can be found [here](https://support.google.com/firebase/answer/7015592).
-
-An example firebase config looks like this:
-
-```js
-const firebaseConfig = {
-  apiKey: "AIzaSyDOCAbC123dEf456GhI789jKl01-MnO",
-  authDomain: "myapp-project-123.firebaseapp.com",
-  databaseURL: "https://myapp-project-123.firebaseio.com",
-  projectId: "myapp-project-123",
-  storageBucket: "myapp-project-123.appspot.com",
-  messagingSenderId: "65211879809",
-  appId: "1:65211879909:web:3ae38ef1cdcb2e01fe5f0c",
-  measurementId: "G-8GSGZQ44ST",
-}
-```
-
-See [firebase.google.com/docs/web/setup](https://firebase.google.com/docs/web/setup) for more details.
-
-> **From Firebase - Caution**: We do not recommend manually modifying an app's Firebase config file or object. If you initialize an app with invalid or missing values for any of these required "Firebase options", then your end users may experience serious issues.
->
-> For open source projects, we generally do not recommend including the app's Firebase config file or object in source control because, in most cases, your users should create their own Firebase projects and point their apps to their own Firebase resources (via their own Firebase config file or object).
+Check out the [documentation](https://authjs.dev/reference/adapter/firebase) to learn how to use this adapter in your project.
