+# 🌐 IPFS Upload - Decentralized File Storage
+
+A modern React application for uploading files, folders, and URLs to the InterPlanetary File System (IPFS) using the latest **Helia** technology.
+
+![IPFS Upload Demo](https://img.shields.io/badge/IPFS-Upload-blue?style=for-the-badge&logo=ipfs)
+![React](https://img.shields.io/badge/React-19.1.1-61dafb?style=for-the-badge&logo=react)
+![Helia](https://img.shields.io/badge/Helia-Latest-orange?style=for-the-badge)
+![Bootstrap](https://img.shields.io/badge/Bootstrap-5-7952b3?style=for-the-badge&logo=bootstrap)
+
+## ✨ Features
+
+### 📁 Multiple Upload Methods
+- **Individual Files**: Upload single or multiple files at once
+- **Entire Folders**: Upload complete directory structures
+- **Remote URLs**: Download and upload files from external URLs
+
+### 🔧 Flexible Configuration
+- **Self-hosted Instance**: Run your own IPFS node
+- **Custom Instance**: Connect to external IPFS instances
+- **Content Pinning**: Ensure your content persists on the network
+
+### 🎨 Modern Interface
+- **Responsive Design**: Works perfectly on desktop and mobile
+- **Dynamic Background**: Automatically changing pastel colors
+- **Real-time Feedback**: Toast notifications and progress indicators
+- **Beautiful UI**: Modern Bootstrap 5 styling with custom enhancements
+
+### 🚀 Advanced Features
+- **CID Copying**: One-click copy to clipboard
+- **File Size Formatting**: Human-readable file sizes
+- **Error Handling**: Comprehensive error messages
+- **Memory Management**: Automatic cleanup of IPFS instances
+
+## 🛠️ Technology Stack
+
+- **Frontend**: React 19.1.1 with Hooks
+- **IPFS**: Helia (next-generation IPFS implementation)
+- **Styling**: Bootstrap 5 + React Bootstrap
+- **Icons**: Emoji-based for universal compatibility
+- **Build Tool**: Create React App
+
+## 📦 Dependencies
+
+### Core IPFS
+```json
+{
+  "@helia/unixfs": "latest",
+  "@helia/http": "latest",
+  "helia": "latest",
+  "@helia/strings": "latest",
+  "@libp2p/websockets": "latest"
+}
+```
+
+### UI & Styling
+```json
+{
+  "bootstrap": "latest",
+  "react-bootstrap": "latest"
+}
+```
+
+## 🚀 Quick Start
+
+### Prerequisites
+- Node.js (v16 or higher)
+- npm or yarn
+- Modern web browser with JavaScript enabled
+
+### Installation
+
+1. **Clone the repository**
+   ```bash
+   git clone <repository-url>
+   cd ipfs-upload
+   ```
+
+2. **Install dependencies**
+   ```bash
+   npm install
+   ```
+
+3. **Start the development server**
+   ```bash
+   npm start
+   ```
+
+4. **Open in browser**
+   Navigate to [http://localhost:3000](http://localhost:3000)
+
+## 🎯 Usage Guide
+
+### 1. Configure Your IPFS Instance
+
+**Self Instance (Recommended for beginners)**
+- Select "Self Instance" radio button
+- The app will create a local IPFS node automatically
+
+**Custom Instance (For advanced users)**
+- Select "Custom Instance" radio button
+- Enter your IPFS instance URL (e.g., `http://localhost:5001/api/v0`)
+- Ensure CORS is properly configured on your instance
+
+### 2. Enable Content Pinning (Optional)
+
+Check the "Persist content (pinned)" checkbox to ensure your uploaded content remains available on the IPFS network and won't be garbage collected.
+
+### 3. Upload Your Content
+
+**Upload Files**
+1. Click on the file input in the green "Upload Files" card
+2. Select one or multiple files
+3. Click "Upload Files"
+
+**Upload Folders**
+1. Click on the folder input in the red "Upload Folder" card
+2. Select a folder (all files and subdirectories will be included)
+3. Click "Upload Folder"
+
+**Upload from URL**
+1. Enter a direct file URL in the yellow "Upload URL" card
+2. Click "Upload URL"
+
+### 4. Access Your Files
+
+Once uploaded, you'll see:
+- **File name** and size
+- **IPFS CID** (Content Identifier)
+- **Direct link** to view on IPFS
+- **Copy CID** button for easy sharing
+- **Pinned status** (if enabled)
+
+## 🔗 IPFS Access
+
+Your uploaded files can be accessed through:
+
+- **IPFS Gateway**: `https://ipfs.io/ipfs/<CID>`
+- **Local Gateway**: `http://localhost:8080/ipfs/<CID>` (if running IPFS locally)
+- **Any IPFS Gateway**: Replace the domain with your preferred gateway
+
+## ⚠️ Important Notes
+
+### Security Considerations
+- **Content Permanence**: Files uploaded to IPFS cannot be deleted
+- **Public Network**: Content is publicly accessible via CID
+- **CORS Requirements**: Custom instances must have CORS enabled
+
+### Browser Compatibility
+- Modern browsers (Chrome, Firefox, Safari, Edge)
+- JavaScript must be enabled
+- Local storage access required
+
+### File Size Limitations
+- Browser memory limitations apply
+- Large files may take longer to process
+- Consider file size when using self-hosted instances

+src/
+├── components/
+│   ├── FileList.js          # Component for displaying uploaded files
+│   └── UploadCard.js        # Reusable upload card component
+├── App.js                   # Main application component
+├── App.css                  # Custom styles

+
+## 🔧 Development
+
+### Available Scripts
+
+- `npm start` - Start development server
+- `npm test` - Run test suite
+- `npm run build` - Build for production
+- `npm run eject` - Eject from Create React App (irreversible)
+
+### Custom Scripts
+
+You can add these to your `package.json`:
+
+```json
+{
+  "scripts": {
+    "analyze": "npm run build && npx serve -s build",
+    "lint": "eslint src --ext .js,.jsx",
+    "format": "prettier --write src/**/*.{js,jsx,css,md}"
+  }
+}
+```
+
+## 🚀 Deployment
+
+### Build for Production
+
+```bash
+npm run build
+```
+
+This creates an optimized build in the `build/` folder.
+
+### Deployment Options
+
+- **GitHub Pages**: Use `gh-pages` package
+- **Netlify**: Connect your repository for automatic deploys
+- **Vercel**: Import your project for instant deployment
+- **Static Hosting**: Upload the `build/` folder to any static host
+
+### Environment Variables
+
+Create a `.env` file for configuration:
+
+```env
+REACT_APP_DEFAULT_GATEWAY=https://ipfs.io
+REACT_APP_ENABLE_ANALYTICS=false
+```
+
