-### Setting up local environment
+If you create a branch and there are conflicting updates in the `main` branch, you can resolve them by rebasing from a check out of your branch:
 
-A quick guide on how to setup _next-auth_ locally to work on it and test out any changes:
+    git fetch
+    git rebase origin/main
 
-The dev application requires you to use `npm@7`.
+If there are any conflicts, you can resolve them and stage the files, then run:
+
+    git rebase --continue
+
+*If there are a lot of changes you may be prompted to step more than once.*
+
+When the rebase is complete (i.e. there are no more conflicts) you should push your changes to your branch before doing anything else:
+
+   git push --force-with-lease
+
+You should see that any conflicts in your PR are now resolved. You can review changes to make sure it contains changes you intended to make.
+
+*If you accidentally sync before pushing, it will trigger a merge. You can use `git merge --abort` to undo the merge.*
+
+You can use `npm run lint:fix` to automatically apply Standard JS rules to resolve formatting differences (tabs vs spaces, line endings, etc).
+
+## Setting up local environment
+
+A quick and dirty 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
-```
+       git clone git@github.com:iaincollins/next-auth.git
+       cd next-auth/
 
-2. Install packages, set up the dev application:
+2. Install packages and run the build command:
 
-```sh
-npm run dev:setup
-```
+       npm i
+       npm run build
 
-3. Populate `.env.local`:
+3. Link your project back to your local copy of next auth:
 
-   Copy `app/.env.local.example` to `app/.env.local`, and add your env variables for each provider you want to test.
+       cd ../your-application
+       npm link ../next-auth
 
-> 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`.
+4. Finally link React between the repo and the version installed in your project:
 
-1. Start the dev application/server:
+       cd ../next-auth
+       npm link ../your-application/node_modules/react
 
-```sh
-npm run dev
-```
+*This is an annoying step and not obvious, but is needed because of how React has been written (otherwise React crashes when you try to use the `useSession()` hook in your project).*
 
-Your dev application will be available on `http://localhost:3000`
+That's it!
 
-That's it! 🎉
+Notes: You may need to repeat both `npm link` steps if you install / update additional dependencies with `npm i`.
 
 If you need an example project to link to, you can use [next-auth-example](https://github.com/iaincollins/next-auth-example).
 
-#### Hot reloading
+### 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.
+You might find it helpful to use the `npm run watch` command in the next-auth project, which will automatically (and silently) rebuild JS and CSS files as you edit them.
 
-> 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!)
+    cd next-auth/
+    npm run watch
 
-> 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.
+If you are working on `next-auth/src/client/index.js` hot reloading will work as normal in your Next.js app.
 
-#### Providers
+However, if you are working on anything else (e.g. `next-auth/src/server/*` etc) then you will need to *stop and start* your app for changes to apply as **Next.js will not hot reload those changes by default**. To facilitate this, you can try [this webpack plugin](https://www.npmjs.com/package/webpack-clear-require-cache-plugin). Note that the `next.config.js` syntax in the plugin README may be out of date. It should look like this:
 
-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:
+```
+const clearRequireCachePlugin = require('webpack-clear-require-cache-plugin')
 
-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)
+module.exports = {
+  webpack: (config, {
+    buildId, dev, isServer, defaultLoaders, webpack,
+  }) => {
+    config.plugins.push(clearRequireCachePlugin([
+      /\.next\/server\/static\/development\/pages/,
+      /\.next\/server\/ssr-module-cache.js/,
+      /next-auth/,
+    ]))
 
-That's it! 🎉 Others will be able to discover this provider much more easily now!
+    return config
+  },
+}
+```
 
-You can look at the existing built-in providers for inspiration.
+### Databases
 
-#### Databases
+Included is a Docker Compose file that starts up MySQL, Postgres, and MongoDB databases on localhost.
 
-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
+It will use port 3306, 5432, and 27017 on localhost respectively; it will not work if are running existing databases on localhost.
+
+You can start them with `npm run db:start` and stop them with `npm run db:stop`.
+
+You will need Docker 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.
-## 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.
+Currently, to run tests you need to first have started local test databases (e.g. using `npm run db:start`).
 
-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 grouping the different commit types in the release notes.
-
-Some recommended 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.
+The databases can take a few seconds to start up, so you might need to give it a minute before running the tests.

+* 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
+### 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.
+You can install the appropriate types via the following command:
 
-The package at `@types/next-auth` is now deprecated.
+```
+npm install --save-dev @types/next-auth
+```
+
+If you encounter any problems with the types package, please create an issue and add the `typescript` label to it.
+
+Alternatively, you can open a pull request directly with your fixes on the [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/next-auth) repository, where you'll find a `next-auth` subfolder.
 
 ## Example
 
 ### Add API Route
 
 ```javascript
-import NextAuth from "next-auth"
-import Providers from "next-auth/providers"
+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,
+  database: process.env.DATABASE_URL
 })
 ```
 
 ### Add React Component
 
 ```javascript
-import { useSession, signIn, signOut } from "next-auth/client"
+import React from 'react'
+import { 
+  useSession, 
+  signin, 
+  signout 
+} from 'next-auth/client'
 
-export default function Component() {
-  const [session, loading] = useSession()
-  if (session) {
-    return (
-      <>
-        Signed in as {session.user.email} <br />

-  }
-  return (
-    <>
-      Not signed in <br />
-      <button onClick={() => signIn()}>Sign in</button>
-    </>
-  )
+export default function myComponent() {
+  const [ session, loading ] = useSession()
+
+  return <p>
+    {!session && <>
+      Not signed in <br/>
