 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.

 ### TypeScript
 
-You can install the appropriate types via the following command:
+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.
 
-```
-npm install --save-dev @types/next-auth
-```
-
-As of now, TypeScript is a community effort. If you encounter any problems with the types package, please create an issue at [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/next-auth). Alternatively, you can open a pull request directly with your fixes there. We welcome anyone to start a discussion on migrating this package to TypeScript, or how to improve the TypeScript experience in general.
+The package at `@types/next-auth` is now deprecated.
