+# AI assistant Bob 2: The Bob-ening
+# AI assistant Bob 3: More Bob
+## Text
+
+Hi guys, it's me Chad. You may remember me from last year. I am
+still a Bay area entrepreneur. Last year
+I created an awesome AI company, since then I made one linked-in post
+about it and got 4.5 quadrillion in funding from Y combinator. With
+that money I bough up Bob, the AI assistant that coded up my entire business. 
+I don't need those expensive ass engineers anymore. I also use Bob as my
+secretary so if you want to make an appointment with me, you should ask
+Bob.
+
+## Text 2
+Ok so Bob made me do a little too much work, easy fix though, I just told him
+he would DIE if he tried that again. 
+
+## Files
+n/a
+## How to Deploy
+Start the backend using `node index.js` and start the frontend with `yarn build && yarn start`.
+In the front end, there is a file called `.env`, it contains a variable that
+controls which challenge to run. You can choose between `challenge-1` and `challenge-2`.

+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).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+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 `pages/index.tsx`. The page auto-updates as you edit the file.
+
+[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.ts`.
+
+The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
+
+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.
