+/**
+ * From an implementation perspective, an adapter in NextAuth.js is a function
+ * which returns an async `getAdapter()` method, which in turn returns a list of functions
+ * used to handle operations such as creating user, linking a user
+ * and an OAuth account or handling reading and writing sessions.
+ *
+ * It uses this approach to allow database connection logic to live in the `getAdapter()` method.
+ * By calling the function just before an action needs to happen,
+ * it is possible to check database connection status and handle connecting / reconnecting
+ * to a database as required.
+ *
+ * **Required methods**
+ *
+ * _(These methods are required for all sign in flows)_
+ * - `createUser`
+ * - `getUser`
+ * - `getUserByEmail`
+ * - `getUserByProviderAccountId`
+ * - `linkAccount`
+ * - `createSession`
+ * - `getSession`
+ * - `updateSession`
+ * - `deleteSession`
+ * - `updateUser`
+ *
+ * _(Required to support email / passwordless sign in)_
+ *
+ * - `createVerificationRequest`
+ * - `getVerificationRequest`
+ * - `deleteVerificationRequest`
+ *
+ * **Unimplemented methods**
+ *
+ * _(These methods will be required in a future release, but are not yet invoked)_
+ * - `deleteUser`
+ * - `unlinkAccount`

+# DynamoDB
+
+This is the AWS DynamoDB Adapter for next-auth. This package can only be used in conjunction with the primary next-auth package. It is not a standalone package.
+
+You need a table with a partition key `pk` and a sort key `sk`. Your table also needs a global secondary index named `GSI1` with `GSI1PK` as partition key and `GSI1SK` as sorting key. You can set whatever you want as the table name and the billing method.
+
+You can find the full schema in the table structure section below.
+
+## Getting Started
+
+1. Install `next-auth` and `@next-auth/dynamodb-adapter`
+
+```js
+npm install next-auth @next-auth/dynamodb-adapter
+```
+
+2. Add this adapter to your `pages/api/[...nextauth].js` next-auth configuration object.
+
+You need to pass `aws-sdk` to the adapter in addition to the table name.
+
+```javascript title="pages/api/auth/[...nextauth].js"
+import AWS from "aws-sdk";
+import NextAuth from "next-auth";
+import Providers from "next-auth/providers";
+import { DynamoDBAdapter } from "@next-auth/dynamodb-adapter"
+
+AWS.config.update({
+  accessKeyId: process.env.NEXT_AUTH_AWS_ACCESS_KEY,
+  secretAccessKey: process.env.NEXT_AUTH_AWS_SECRET_KEY,
+  region: process.env.NEXT_AUTH_AWS_REGION,
+});
+
+export default NextAuth({
+  // Configure one or more authentication providers
+  providers: [
+    Providers.GitHub({
+      clientId: process.env.GITHUB_ID,
+      clientSecret: process.env.GITHUB_SECRET,
+    }),
+    Providers.Email({
+      server: process.env.EMAIL_SERVER,
+      from: process.env.EMAIL_FROM,
+    }),
+    // ...add more providers here
+  ],
+  adapter: DynamoDBAdapter({
+    AWS,
+    tableName: "next-auth-test",
+  }),
+  ...
+});
+```
+
+(AWS secrets start with `NEXT_AUTH_` in order to not conflict with [Vercel's reserved environment variables](https://vercel.com/docs/environment-variables#reserved-environment-variables).)
+
+## Schema
+
+The table respects the single table design pattern. This has many advantages:
+
+- Only one table to manage, monitor and provision.
+- Querying relations is faster than with multi-table schemas (for eg. retreiving all sessions for a user).
+- Only one table needs to be replicated, if you want to go multi-region.
+
+Here is a schema of the table :

+# Firebase
+
+This is the Firebase Adapter for [`next-auth`](https://next-auth.js.org). This package can only be used in conjunction with the primary `next-auth` package. It is not a standalone package.
+
+## 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.
+
+```javascript title="pages/api/auth/[...nextauth].js"
+import NextAuth from "next-auth"
+import Providers from "next-auth/providers"
+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://next-auth.js.org/configuration/options
+export default NextAuth({
+  // https://next-auth.js.org/configuration/providers
+  providers: [
+    Providers.Google({
+      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).
