Here's the properly ordered and formatted README.md:

# Chat Application

A real-time chat application built with Next.js, Express.js, Prisma, and PostgreSQL. This project includes features such as chatbot interactions and API validation using Zod.

The chatbot mimics a typical chatbot interaction but currently sends a hardcoded response for testing purposes instead of generating dynamic replies.

## 🚀 Technologies Used

- **Frontend:** Next.js, TailwindCSS, Redux Toolkit
- **Backend:** Express.js, Prisma, PostgreSQL
- **API Validation:** Zod
- **Documentation:** Swagger
- **State Management:** Redux Toolkit
