+# Welcome to React Router!
+
+A modern, production-ready template for building full-stack React applications using React Router.
+
+## Features
+
+- 🚀 Server-side rendering
+- ⚡️ Hot Module Replacement (HMR)
+- 📦 Asset bundling and optimization
+- 🔄 Data loading and mutations
+- 🔒 TypeScript by default
+- 🎉 TailwindCSS for styling
+- 📖 [React Router docs](https://reactrouter.com/)
+
+## Getting Started
+
+### Installation
+
+Install the dependencies:
+
+```bash
+npm install
+```
+
+### Development
+
+Start the development server with HMR:
+
+```bash
+npm run dev
+```
+
+Your application will be available at `http://localhost:5173`.
+
+## Previewing the Production Build
+
+Preview the production build locally:
+
+```bash
+npm run preview
+```
+
+## Building for Production
+
+Create a production build:
+
+```bash
+npm run build
+```
+
+## Deployment
+
+Deployment is done using the Wrangler CLI.
+
+To build and deploy directly to production:
+
+```sh
+npm run deploy
+```
+
+To deploy a preview URL:
+
+```sh
+npx wrangler versions upload
+```
+
+You can then promote a version to production after verification or roll it out progressively.
+
+```sh
+npx wrangler versions deploy
+```
+
+## Styling
+
+This template comes with [Tailwind CSS](https://tailwindcss.com/) already configured for a simple default starting experience. You can use whatever CSS framework you prefer.
+
+---
+
+Built with ❤️ using React Router.
