-This adapter is still experimental and does not work with Auth.js 4 or newer. If you would like to help out upgrading it, please visit [this PR](https://github.com/nextauthjs/next-auth/pull/3873)
-:::
-
-This is the Firebase Adapter for [`next-auth`](https://authjs.dev). This package can only be used in conjunction with the primary `next-auth` package. It is not a standalone package.
-
-## Getting Started
-
-1. Install the necessary packages
-
-```bash npm2yarn
-npm install next-auth @next-auth/firebase-adapter@experimental
-```
-
-2. Add this adapter to your `pages/api/auth/[...nextauth].js` next-auth configuration object.
-
-```javascript title="pages/api/auth/[...nextauth].js"
-import NextAuth from "next-auth"
-import GoogleProvider from "next-auth/providers/google"
-import { FirebaseAdapter } from "@next-auth/firebase-adapter"
-
-import firebase from "firebase/app"
-import "firebase/firestore"
-
-const firestore = (
-  firebase.apps[0] ?? firebase.initializeApp(/* your config */)
-).firestore()
-
-// 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/
-  providers: [
-    GoogleProvider({
-      clientId: process.env.GOOGLE_ID,
-      clientSecret: process.env.GOOGLE_SECRET,
-    }),
-  ],
-  adapter: FirebaseAdapter(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.
-
-:::tip **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).

-## 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.

+ * #### Usage
+ *
+ * First, create a Firebase project and generate a service account key.
+ * Visit: `https://console.firebase.google.com/u/0/project/{project-id}/settings/serviceaccounts/adminsdk` (replace `{project-id}` with your project's id)
+ *
+ * Now you have a few options to authenticate with the Firebase Admin SDK in your app:
+ *
+ * ##### 1. `GOOGLE_APPLICATION_CREDENTIALS` environment variable:
+ *  - Download the service account key and save it in your project. (Make sure to add the file to your `.gitignore`!)
+ *  - Add [`GOOGLE_APPLICATION_CREDENTIALS`](https://cloud.google.com/docs/authentication/application-default-credentials#GAC) to your environment variables and point it to the service account key file.
+ *  - The adapter will automatically pick up the environment variable and use it to authenticate with the Firebase Admin SDK.
+ *
+ * @example
+ * ```ts title="pages/api/auth/[...nextauth].ts"
+ * import NextAuth from "next-auth"
+ * import { FirestoreAdapter } from "@next-auth/firebase-adapter"
+ *
+ * export default NextAuth({
+ *   adapter: FirestoreAdapter(),
+ *   // ...
+ * })
+ * ```
+ *
+ * ##### 2. Service account values as environment variables
+ *
+ * - Download the service account key to a temporary location. (Make sure to not commit this file to your repository!)
+ * - Add the following environment variables to your project: `FIREBASE_PROJECT_ID`, `FIREBASE_CLIENT_EMAIL`, `FIREBASE_PRIVATE_KEY`.
+ * - Pass the config to the adapter, using the environment variables as shown in the example below.
+ *
+ * @example
+ * ```ts title="pages/api/auth/[...nextauth].ts"
+ * import NextAuth from "next-auth"
+ * import { FirestoreAdapter } from "@next-auth/firebase-adapter"
+ * import { cert } from "firebase-admin/app"
+ *
+ * export default NextAuth({
+ *  adapter: FirestoreAdapter({
+ *    credential: cert({
+ *      projectId: process.env.FIREBASE_PROJECT_ID,
+ *      clientEmail: process.env.FIREBASE_CLIENT_EMAIL,
+ *      privateKey: process.env.FIREBASE_PRIVATE_KEY,
+ *    })
+ *  })
+ *  // ...
+ * })
+ * ```
+ *
+ * ##### 3. Use an existing Firestore instance
+ *
+ * If you already have a Firestore instance, you can pass that to the adapter directly instead.
+ *
+ * :::note
+ * When passing an instance and in a serverless environment, remember to handle duplicate app initialization.
+ * :::
+ *
+ * :::tip
+ * You can use the {@link initFirestore} utility to initialize the app and get an instance safely.
+ * :::
+ *
+ * @example
+ * ```ts title="pages/api/auth/[...nextauth].ts"
+ * import NextAuth from "next-auth"
+ * import { FirestoreAdapter } from "@next-auth/firebase-adapter"
+ * import { firestore } from "lib/firestore"
+ *
+ * export default NextAuth({
+ *  adapter: FirestoreAdapter(firestore),
+ *  // ...
+ * })
+ * ```
