-# Authentication
-
-To use oAuth you need to configure environment variables with ID and secret and configure the service accordingly.
-
-This project comes pre-configured to handle Facebook, Google and Twitter oAuth if you provide the ID and sercret for the service via environment variables.
-
-You can pass them on the command line or put them in `.env` file which will be loaded at startup (see [.env.example](https://github.com/iaincollins/next-auth/blob/master/example/.env.example) for an example).
-
-If you want to add new oAuth providers (such as GitHub), you will need to:
-
-* Add the oauth provider configuration in next-auth.providers.js
-* Add a field to your User model (in 'index.js') with the name of the provider
-* Configure the service to point to your website (as in the examples below)
-* Specify the environment variables at run time
-
-## Configuring your account
-
-These guides are approximate as exactly how to configure oAuth varies for each provider and tends to change when they update their developer portals, which can be quite often. If you can't see the options mentioned, try exploring the UI in the developer portal or configuration pages.
-
-Due to the volume of requests I'm not usually able to help with specific problems but pull requests with improved or extended instructions are very welcome.
-
-Tip: Twitter's oAuth implementation is the most permissive and easiest to configure, you may want to start with it. If you run into problems, you might 
-want to check email sign-in is working as baseline.
-
-Please note that Facebook oAuth cannot be used to sign in to 'localhost' and that if you want to sign in to `localhost` with Google+ you must specifically add something like `http://localhost:3000/auth/oauth/google/callback` as a authorized redirect URI for your application.

+# Contributing guide
+
+Contributions and feedback on your experience of using this software are welcome.
+
+This includes bug reports, feature requests, ideas, pull requests, and examples of how you have used this software.
+
+Please see the [Code of Conduct](CODE_OF_CONDUCT.md) and follow any templates configured in GitHub when reporting bugs, requesting enhancements, or contributing code.
+
+Please raise any significant new functionality or breaking change an issue for discussion before raising a Pull Request for it.
+
+## For contributors
+
+Anyone can be a contributor. Either you found a typo, or you have an awesome feature request you could implement, we encourage you to create a Pull Request.
+### Pull Requests
+
+* The latest changes are always in `main`, so please make your Pull Request against that branch.
+* Pull Requests should be raised for any change
+* Pull Requests need approval of a [core contributor](https://next-auth.js.org/contributors#core-team) before merging
+* We use ESLint/Prettier for linting/formatting, so please run `npm run lint:fix` before committing to make resolving conflicts easier (VSCode users, check out [this ESLint extension](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) and [this Prettier extension](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode) to fix lint and formatting issues in development)
+* We encourage you to test your changes, and if you have the opportunity, please make those tests part of the Pull Request
+* If you add new functionality, please provide the corresponding documentation as well and make it part of the Pull Request
+
+### Setting up local environment
+
+A quick guide on how to setup *next-auth* locally to work on it and test out any changes:
+
+1. Clone the repo:
+```sh
+git clone git@github.com:nextauthjs/next-auth.git
+cd next-auth
+```
+
+2. Install packages:
+```sh
+npm i && npm dev:setup
+```
+
+3. Populate `.env.local`:
+   
+    Copy `app/.env.local.example` to `app/.env.local`, and add your env variables for each provider you want to test.
+
+> NOTE: You can add any environment variables to .env.local that you would like to use in your dev app.
+> You can find the next-auth config under`app/pages/api/auth/[...nextauth].js`.
+
+1. Start the dev application/server:
+```sh
+npm run dev
+```
+
+Your dev application will be available on ```http://localhost:3000```
+
+That's it! 🎉
+
+If you need an example project to link to, you can use [next-auth-example](https://github.com/iaincollins/next-auth-example).
+
+#### Hot reloading
+
+When running `npm run dev`, you start a Next.js dev server on `http://localhost:3000`, which includes hot reloading out of the box. Make changes on any of the files in `src` and see the changes immediately.
+
+> NOTE: When working on CSS, you will have to manually refresh the page after changes. The reason for this is our pages using CSS are server-side rendered. (Improving this through a PR is very welcome!)
+
+> NOTE: The setup is as follows: The development application lives inside the `app` folder, and whenever you make a change to the `src` folder in the root (where next-auth is), it gets copied into `app` every time (gitignored), so Next.js can pick them up and apply hot reloading. This is to avoid some annoying issues with how symlinks are working with different React builds, and also to provide a super-fast feedback loop while developing core features.
+
+#### Providers
+
+If you think your custom provider might be useful to others, we encourage you to open a PR and add it to the built-in list so others can discover it much more easily! You only need to add two changes:
+1. Add your config: [`src/providers/{provider}.js`](https://github.com/nextauthjs/next-auth/tree/main/src/providers) (Make sure you use a named default export, like `export default function YourProvider`!)
+2. Add provider documentation: [`www/docs/providers/{provider}.md`](https://github.com/nextauthjs/next-auth/tree/main/www/docs/providers)
+
+That's it! 🎉 Others will be able to discover this provider much more easily now!
+
+You can look at the existing built-in providers for inspiration.
+
+#### Databases
+
+Included is a Docker Compose file that starts up MySQL, PostgreSQL, and MongoDB databases on localhost.
+
+It will use port `3306`, `5432`, and `27017` on localhost respectively; please make sure those ports are not used by other services on localhost.
+
+You can start them with `npm run db:start` and stop them with `npm run db:stop`.
+
+You will need Docker and Docker Compose installed to be able to start / stop the databases.
+
+When stopping the databases, it will reset their contents.
+
+#### Testing
+
+Tests can be run with `npm run test`.
+
+Automated tests are currently crude and limited in functionality, but improvements are in development.
+
+Currently, to run tests you need to first have started local test databases (e.g. using `npm run db:start`).
+
+The databases can take a few seconds to start up, so you might need to give it a minute before running the tests.
+
+## For maintainers
+
+We use [semantic-release](https://github.com/semantic-release/semantic-release) together with [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0) to automate releases. This makes the maintainenance process easier and less error-prone to human error. Please study the "Conventional Commits" site to understand how to write a good commit message.
+
+When accepting Pull Requests, make sure the following:
+
+* Use "Squash and merge"
+* Make sure you merge contributor PRs into `main`
+* Rewrite the commit message to conform to the `Conventional Commits` style. Check the "Recommended Scopes" section for further advice.
+* Optionally link issues the PR will resolve (You can add "close" in front of the issue numbers to close the issues automatically, when the PR is merged. `semantic-release` will also comment back to connected issues and PRs, notifying the users that a feature is added/bug fixed, etc.)
+
+### Recommended Scopes
+
+A typical conventional commit looks like this:
+```
+type(scope): title
+
+body
+```
+
+Scope is the part that will help groupping the different commit types in the release notes.
+
+Some recommened scopes are:
+
+- **provider** - Provider related changes. (eg.: "feat(provider): add X provider", "docs(provider): fix typo in X documentation"
+- **adapter** - Adapter related changes. (eg.: "feat(adapter): add X provider", "docs(provider): fix typo in X documentation"
+- **db** - Database related changes. (eg.: "feat(db): add X database", "docs(db): fix typo in X documentation"
+- **deps** - Adding/removing/updating a dependency (eg.: "chore(deps): add X")
+  
+> NOTE: If you are not sure which scope to use, you can simply ignore it. (eg.: "feat: add something"). Adding the correct type already helps a lot when analyzing the commit messages.
+
+
+### Skipping a release
+
+Every commit that contains [skip release] or [release skip] in their message will be excluded from the commit analysis and won't participate in the release type determination. This is useful, if the PR being merged should not trigger a new `npm` release.

-# NextAuthClient
-
-## About NextAuthClient
-
-NextAuthClient is session library for the [next-auth](https://www.npmjs.com/package/next-auth) module.
-
-## Methods
-
-It provides the following methods, all of which return a promise.
-
-### NextAuthClient.init({ req, force })
-
-Isometric (can be used in server side rendering when passed optional `req` object).
-
-Return the current session.
-
-When using Server Side Rendering and passed `req` object from **getInitialProps({req})** it will read the data from it.
-
-When using Client Side Rendering it will use localStorage (if avalible) to check for cached session data and if not found or expired it call the `/auth/session` end point.
-
-### NextAuthClient.signin(string or object)
-
-Client side only method.
-
-If passed a string treats it as an email address, generates an email sign in token and makes POST request to `/auth/email/signin`.
-
-If passed an object treats it as a form to be handled by a custom signIn() function and makes a POST request to `/auth/signin`.
-
-### NextAuthClient.signout()
-
-Client side only method. Triggers the current session to be destroyed.
-
-Makes POST request to `/auth/signout`.
-
-### NextAuthClient.csrfToken()
-
-Client side only method. Returns the latest CSRF Token.
-
-Note: When rendering server side, this is accessible from NextAuthClient.init().
-
-Makes GET request to `/auth/csrf`.
-
-### NextAuthClient.linked({ req })
-
-Isometric method (can be used in server side rendering when passed optional `req` object).
-
-Returns a list of linked/unlinked oAuth providers.
-
-This is useful on account management pages where you want to display buttons to link / unlink accounts.
-
-Makes GET request to `/auth/linked`.
-
-### NextAuthClient.providers({ req })
-
-Isometric method (can be used in server side rendering when passed optional `req` object).
-
-Returns a list of all configured oAuth providers.
-
-It includes their names, sign in URLs and callback URLs.
-
-This is useful on sign in pages (e.g. to render sign in links for all configured providers).
-
-Makes GET request to `/auth/providers`.
-
-## Example
-
-````javascript
-import React from 'react'
-import { NextAuth } from 'next-auth/client'
-
-export default class extends React.Component {
-  static async getInitialProps({req}) {
-    return {
-      session: await NextAuth.init({req})
-    }
-  }
-  render() {
-    if (this.props.session.user) {
-      return(
-        <div>
-          <p>You are logged in as {this.props.session.user.name || this.props.session.user.email}.</p>
-        </div>
-        )
-    } else {
-      return(
-        <div>
-          <p>You are not logged in.</p>
-        </div>
-      )
-    }
-  }
-}

-## About NextAuth
+## Overview
 
-NextAuth is an authentication library for Next.js projects.
+NextAuth.js is a complete open source authentication solution for [Next.js](http://nextjs.org/) applications.
 
-The NextAuth library uses Express and Passport, the most commonly used authentication library for Node.js, to provide support for signing in with email and with services like Facebook, Google and Twitter.
-
-NextAuth adds Cross Site Request Forgery (CSRF) tokens and HTTP Only cookies, supports universal rendering and does not require client side JavaScript.
-
-It adds session support without using client side accessible session tokens, providing protection against Cross Site Scripting (XSS) and session hijacking, while leveraging localStorage where available to cache non-critical session state for optimal performance in Single Page Apps.
-
-The NextAuth comes with a client library, designed to work with React pages powered by Next.js to easily add universal session support to sites.
-
-It contains an [example site](https://github.com/iaincollins/next-auth/tree/master/example) that shows how to use it in a simple project. It's also used in the [nextjs-starter.now.sh](https://nextjs-starter.now.sh) project, which provides a more complete example with a live demo.
-
-Note: As of version 1.5 NextAuth is also compatible non-Next.js React projects, just pass `null` instead of a nextApp instance when calling `nextAuth()`.
-
-You will need to handle setting up routes before and after initialising NextAuth if you are not using Next.js. NextAuth lets you pass an instance of express as 'expressApp' option (and returns it in the response).
-
-## Example Client Usage
-
-````javascript
-import React from 'react'
-import { NextAuth } from 'next-auth/client'
-
-export default class extends React.Component {
-  static async getInitialProps({req}) {
-    return {
-      session: await NextAuth.init({req})
-    }
-  }
-  render() {
-    if (this.props.session.user) {
-      return(
-        <div>
-          <p>You are logged in as {this.props.session.user.name || this.props.session.user.email}.</p>
-        </div>
-        )
-    } else {
-      return(
-        <div>
-          <p>You are not logged in.</p>
-        </div>
-      )
-    }
-  }
-}
-````
-
-See [Documentation for the NextAuth Client](https://github.com/iaincollins/next-auth/blob/master/README-CLIENT.md) for more information on how to interact with the client.
-
-## Routes
-
-NextAuth adds a number of routes under `/auth':
-
-* POST `/auth/email/signin` - Request Sign In Token
-* GET `/auth/email/signin/:token` - Validate Sign In Token
-* POST `/auth/signout` - Sign Out
-* GET `/auth/csrf` - CSRF endpoint for Single Page Apps
-* GET `/auth/session` - Session endpoint for Single Page Apps
-* GET `/auth/linked` - View linked accounts for Single Page Apps
-
-All POST routes request must include a CSRF token.
-
-CSRF, Session and Linked Account endpoints are provided for Single Page Apps.
-
-Note: Session Tokens are stored in HTTP Only cookies to prevent session hijacking and protect against Cross Site Scripting (XSS) attacks. Only HTTP requests that originate from the original domain are able to read from them.
-
-In addition, it will add the following routes for each oAuth provider currently configured:
-
-* GET `/auth/oauth/${provider}`
-* GET `/auth/oauth/${provider}/callback`
-* POST `/auth/oauth/${provider}/unlink`
-
-You can see which routes are configured and the callback URLs defined for them via this route:
-
-* GET `/auth/providers`
-
-It will return a JSON object with the current oAuth provider configuration:
-
-````json
-{
-  "Facebook": {
-    "signin": "/auth/oauth/facebook",
-    "callback": "/auth/oauth/facebook/callback"
-  },
-  "Google": {
-    "signin": "/auth/oauth/google",
-    "callback": "/auth/oauth/google/callback"
-  },
-  "Twitter": {
-    "signin": "/auth/oauth/twitter",
-    "callback": "/auth/oauth/twitter/callback"
-  }
-}
-````
-
-Note: The `/auth` prefix is configurable via an option in the module, but it is currently hard coded in the client component, so you probably don't want to change it. It will be configurable in future releases.
+It is designed from the ground up to support Next.js and Serverless.
 
 ## Getting Started
 
-Create an `index.js` file in the root of your Next.js project containing the following:
+```
+npm install --save next-auth
+```
 
-````javascript
-const next = require('next')
-const nextAuth = require('next-auth')
-const nextAuthConfig = require('./next-auth.config')
+The easiest way to continue getting started, is to follow the [getting started](https://next-auth.js.org/getting-started/example) section in our docs. 
 
-require('dotenv').load()
+We also have a section of [tutorials](https://next-auth.js.org/tutorials) for those looking for more specific examples.
 
-const nextApp = next({
-  dir: '.',
-  dev: (process.env.NODE_ENV === 'development')
+See [next-auth.js.org](https://next-auth.js.org) for more information and documentation.
+
+## Features
+
+### Flexible and easy to use
+
+* Designed to work with any OAuth service, it supports OAuth 1.0, 1.0A and 2.0
+* Built-in support for [many popular sign-in services](https://next-auth.js.org/configuration/providers)
+* Supports email / passwordless authentication
+* Supports stateless authentication with any backend (Active Directory, LDAP, etc)
+* Supports both JSON Web Tokens and database sessions
+* Designed for Serverless but runs anywhere (AWS Lambda, Docker, Heroku, etc…)
+
+### Own your own data
+
+NextAuth.js can be used with or without a database.
+
+* An open source solution that allows you to keep control of your data
+* Supports Bring Your Own Database (BYOD) and can be used with any database
+* Built-in support for [MySQL, MariaDB, Postgres, Microsoft SQL Server, MongoDB and SQLite](https://next-auth.js.org/configuration/databases)
+* Works great with databases from popular hosting providers
+* Can also be used *without a database* (e.g. OAuth + JWT)
+
+### Secure by default
+
+* Promotes the use of passwordless sign in mechanisms
+* Designed to be secure by default and encourage best practice for safeguarding user data
+* Uses Cross Site Request Forgery Tokens on POST routes (sign in, sign out)
+* Default cookie policy aims for the most restrictive policy appropriate for each cookie
+* When JSON Web Tokens are enabled, they are signed by default (JWS) with HS512
+* Use JWT encryption (JWE) by setting the option `encryption: true` (defaults to A256GCM)
+* Auto-generates symmetric signing and encryption keys for developer convenience
+* Features tab/window syncing and keepalive messages to support short lived sessions
+* Attempts to implement the latest guidance published by [Open Web Application Security Project](https://owasp.org/)
+
+Advanced options allow you to define your own routines to handle controlling what accounts are allowed to sign in, for encoding and decoding JSON Web Tokens and to set custom cookie security policies and session properties, so you can control who is able to sign in and how often sessions have to be re-validated. 
+
+### TypeScript
+
+NextAuth.js comes with built-in types. For more information and usage, check out the [TypeScript section](https://next-auth.js.org/getting-started/typescript) in the documentaion.
+
+The package at `@types/next-auth` is now deprecated.
+
+## Example
+
+### Add API Route
+
+```javascript
+import NextAuth from 'next-auth'
+import Providers from 'next-auth/providers'
+
+export default NextAuth({
+  providers: [
+    // OAuth authentication providers
+    Providers.Apple({
+      clientId: process.env.APPLE_ID,
+      clientSecret: process.env.APPLE_SECRET
+    }),
+    Providers.Google({
+      clientId: process.env.GOOGLE_ID,
+      clientSecret: process.env.GOOGLE_SECRET
+    }),
+    // Sign in with passwordless email link
+    Providers.Email({
+      server: process.env.MAIL_SERVER,
+      from: '<no-reply@example.com>'
+    }),
+  ],
+  // SQL or MongoDB database (or leave empty)
+  database: process.env.DATABASE_URL
 })
+```
 
-nextApp.prepare()
-.then(async () => {
-  const nextAuthOptions = await nextAuthConfig()
-  const nextAuthApp = await nextAuth(nextApp, nextAuthOptions)  
-  console.log(`Ready on http://localhost:${process.env.PORT || 3000}`)
-})
-.catch(err => {
-  console.log('An error occurred, unable to start the server')
-  console.log(err)
-})
-````
+### Add React Component
 
-You can add the following to your `package.json` file to start the project:
+```javascript
+import {
+  useSession, signIn, signOut
+} from 'next-auth/client'
 
-````json
-"scripts": {
-  "dev": "NODE_ENV=development node index.js",
-  "build": "next build",
-  "start": "node index.js"
+export default function Component() {
+  const [ session, loading ] = useSession()
+  if(session) {
+    return <>
+      Signed in as {session.user.email} <br/>
+      <button onClick={() => signOut()}>Sign out</button>
+    </>
+  }
+  return <>
+    Not signed in <br/>
+    <button onClick={() => signIn()}>Sign in</button>
+  </>
 }
-````
+```

-* [next-auth.config.js](https://github.com/iaincollins/next-auth/tree/master/example/next-auth.config.js)
-* [next-auth.functions.js](https://github.com/iaincollins/next-auth/tree/master/example/next-auth.functions.js)
-* [next-auth.providers.js](https://github.com/iaincollins/next-auth/tree/master/example/next-auth.providers.js)
-
-
-You can also add a **.env** file to the root of the project as a place to specify configuration options. The provided example files for NextAuth will use one if there is is one.

-
-### next-auth.config.js
-
-Basic configuration of NextAuth is handled in **next-auth.config.js**.
-
-It is also where the **next-auth.functions.js** and **next-auth.providers.js** files are loaded.
-
-### next-auth.functions.js
-
-Methods for user management and sending email are defined in **next-auth.functions.js**
-
-The example configuration provided is for Mongo DB. By defining the behaviour in these functions you can use NextAuth with any database, including a relational database that uses SQL.
-
-#### Required
-
-* find({id,email,emailToken,provider})
-* insert(user, oAuthProfile, providerParams)
-* update(user, oAuthProfile, providerParams)
-* remove(id)
-* serialize(user)
-* deserialize(id)
-
-#### Optional
-
-* sendSigninEmail({email, url, req})
-* signIn({form, req})
-
-The `sendSigninEmail()` method is used to send an email for email token based sign in (one time use passwords). Omit it or set it to null to disable email based sign in.
-
-The `signIn()` method is used to handle authenticating with custom credentials (e.g. username and password, 2FA token, etc). Omit it or leave it undefined unless you need it.
-
-You can use any combination of authentication methods (email, credentials, oAuth providers).
-
-### next-auth.providers.js 
-
-Configuration for oAuth providers are defined in **next-auth.providers.js**
-
-It includes configuration examples for Facebook, Google and Twitter oAuth, which can easily be copied and replicated to add support for signing in other oAuth providers.
-
-For tips on configuring oAuth see [AUTHENTICATION.md](https://github.com/iaincollins/next-auth/tree/master/AUTHENTICATION.md).

-# NextAuth Example
-
-## About NextAuth Example
-
-This is an example of how to use the [NextAuth](https://www.npmjs.com/package/next-auth) module.
-
-## Getting Started
-
-This project as is run the same way as any Next.js project.
-
-To run it locally, just use:
-
-    npm run dev
-
-To run it it production mode, use:
-
-    npm build
-    npm start
-
-## Using NextAuth
-
-NextAuth is included in this project here:
-
-* index.js
-
-## Pages
-
-This example includes the following pages:
-
-* pages/index.js
-* pages/auth/index.js
-* pages/auth/error.js
-* pages/auth/check-email.js
-* pages/auth/callback.js
-
-The file `pages/auth/credentials.js` provides an additional example of how to use a custom authentication handler defined in `next-auth.functions.js`.
-
-## Configuration
-
-It also includes the following configuration files:
-
-* next-auth.config.js
-* next-auth.functions.js
-* next-auth.providers.js
-
-An example **.env** file is provided in **.env.example** which you can copy over to use for simple configuration:
-
-````
-SERVER_URL=http://localhost:3000
-MONGO_URI=mongodb://localhost:27017/my-database
-FACEBOOK_ID=
-FACEBOOK_SECRET=
-GOOGLE_ID=
-GOOGLE_SECRET=
-TWITTER_KEY=
-TWITTER_SECRET=
-EMAIL_FROM=username@gmail.com
-EMAIL_SERVER=smtp.gmail.com
-EMAIL_PORT=465
-EMAIL_USERNAME=username@gmail.com
-EMAIL_PASSWORD=
-````
-
-If you don't specify a MONGO_URI it will use an in-memory data store for user and session data.
-
-If you don't specify oAuth or SMTP email details you will not be able to log in.
-
-For a more complete example with live demo see [nextjs-starter.now.sh](https://nextjs-starter.now.sh/examples/authentication).
