-This is a [Next.js](https://nextjs.org/) project bootstrapped with
-[`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
+# `nextjs` integration example
 
-## Getting Started
+Shows how to use `@nucypher/pre` in Next.js.
 
-First, run the development server:
+## Usage
 
 ```bash
-npm run dev
-# or
-yarn dev
-# or
+pnpm install
 pnpm dev
-# or
-bun dev
 ```
-
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the
-result.
-
-You can start editing the page by modifying `app/page.tsx`. The page
-auto-updates as you edit the file.
-
-This project uses
-[`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to
-automatically optimize and load Inter, a custom Google Font.
-
-## Learn More
-
-To learn more about Next.js, take a look at the following resources:
-
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js
-  features and API.
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
-
-You can check out
-[the Next.js GitHub repository](https://github.com/vercel/next.js/) - your
-feedback and contributions are welcome!
-
-## Deploy on Vercel
-
-The easiest way to deploy your Next.js app is to use the
-[Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme)
-from the creators of Next.js.
-
-Check out our
-[Next.js deployment documentation](https://nextjs.org/docs/deployment) for more
-details.
