-## Description 🐜
-
-Please provide a clear and concise description of the bug in NextAuth.js.
-
-🚧 – _Do not report bugs with your own project here; ask for help [by raising a question instead](https://github.com/nextauthjs/next-auth/issues/new?assignees=&labels=question&template=question.md) - this helps us a lot with administration overhead._
-
-## How to reproduce ☕️
-
-We encourage you to use one of the templates set up on **CodeSandbox** to reproduce your issue:
-
-- [`next-auth-example`](https://codesandbox.io/s/next-auth-example-1kktb)
-- [`next-auth-typescript-example`](https://codesandbox.io/s/next-auth-typescript-example-se32w)
-
-🚧 – _If you don't provide any way to reproduce the bug, the issue is at risk of being closed._
-
-## Screenshots / Logs 📽
-
-**Help us help you**. We can address the bug you found much faster if you provide contextual screenshots or screen recordings showcasing the issue.
-
-See [Kap](https://getkap.co/) for a good, easy-to-use, cross-platform screen recording tool.
-
-## Environment 🖥
-
-Please run this command:
-
-```
-$ npx envinfo --system --binaries --browsers --npmPackages "{next-auth}"
-```
-
-and paste the output here.
-
-## Contributing 🙌🏽
-
-It takes a lot of work 🏋🏻‍♀️ maintaining a library like `next-auth`; any contribution is more than welcome 💚
-
-In case you're willing to help fix this bug, please let us know here, and we'll reach you 😊 . Otherwise, you can have a look at the issues labelled with [`"good first issue"`](https://github.com/nextauthjs/next-auth/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) and pick any of them.

-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.

+If you would like to contribute to an existing database adapter or help create a new one, head over to the [nextauthjs/adapters](https://www.github.com/nextauthjs/adapters) repository and follow the instructions provided there.
 #### 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 maintenance 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.)

-* 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/)

 ### 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 documentation.
 
-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'
+// pages/api/auth/[...nextauth].js
+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
+      clientSecret: process.env.APPLE_SECRET,
     }),
     Providers.Google({
       clientId: process.env.GOOGLE_ID,
-      clientSecret: process.env.GOOGLE_SECRET
+      clientSecret: process.env.GOOGLE_SECRET,
     }),
     // Sign in with passwordless email link
     Providers.Email({
       server: process.env.MAIL_SERVER,
-      from: '<no-reply@example.com>'
+      from: "<no-reply@example.com>",
     }),
   ],
-  // SQL or MongoDB database (or leave empty)
-  database: process.env.DATABASE_URL
 })
 ```
 
-### Add React Component
+### Add React Hook
+
+The `useSession()` React Hook in the NextAuth.js client is the easiest way to check if someone is signed in.
 
 ```javascript
-import {
-  useSession, signIn, signOut
-} from 'next-auth/client'
+import { useSession, signIn, signOut } from "next-auth/react"
 
 export default function Component() {
-  const [ session, loading ] = useSession()
-  if(session) {
-    return <>
-      Signed in as {session.user.email} <br/>
-      <button onClick={() => signOut()}>Sign out</button>
-    </>
+  const { data: session } = 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>
-  </>
+  return (
+    <>
+      Not signed in <br />
+      <button onClick={() => signIn()}>Sign in</button>
+    </>
+  )
 }
 ```
 
-## Acknowledgements
+### Share/configure session state
+
+Use the `<SessionProvider>` to allows instances of `useSession()` to share the session object across components. It also takes care of keeping the session updated and synced between tabs/windows.
+
+```jsx title="pages/_app.js"
+import { SessionProvider } from "next-auth/react"
+
+export default function App({
+  Component, 
+  pageProps: { session, ...pageProps }
+}) {
+  return (
+    <SessionProvider session={session}>
+      <Component {...pageProps} />
+    </SessionProvider>
+  )
+}
+```
