+# OpChan
+
+A decentralized forum application built as a Proof of Concept for a Waku-powered discussion platform. OpChan enables users to create "cells" (discussion boards), make posts, and engage in threaded conversations using Bitcoin Ordinal verification and the Waku protocol for decentralized messaging.
+
+## Quick Start
+
+### Prerequisites
+
+- Node.js 18+ and npm
+- [Phantom Wallet](https://phantom.app/) browser extension
+- Bitcoin Ordinals (required for posting, optional for reading)
+
+### Installation
+
+1. **Clone the repository**
+   ```bash
+   git clone https://github.com/waku-org/OpChan.git
+   cd OpChan
+   ```
+
+2. **Install dependencies**
+   ```bash
+   npm install
+   ```
+
+3. **Setup environment variables**
+   ```bash
+   cp .env.example .env
+   ```
+   
+   Edit `.env` to configure development settings:
+   ```env
+   # Set to 'true' to bypass verification in development
+   VITE_OPCHAN_MOCK_ORDINAL_CHECK=false
+   ```
+
+4. **Start development server**
+   ```bash
+   npm run dev
+   ```

+
+## Usage
+
+### Getting Started
+
+1. **Connect Wallet**: Click "Connect Wallet" and approve the Phantom wallet connection
+2. **Verify Ordinals**: The app will check if your wallet contains Logos Operator Bitcoin Ordinals
+3. **Browse Cells**: View existing discussion boards on the dashboard
+4. **Create Content**: Create new cells, posts, or comments (requires Ordinals)
+5. **Moderate**: Cell creators can moderate their boards
+
+### Authentication Flow
+
+OpChan uses a two-tier authentication system:
+
+1. **Wallet Connection**: Initial connection to Phantom wallet
+2. **Key Delegation**: Optional browser key generation for improved UX
+   - Reduces wallet signature prompts
+   - 24-hour validity period
+   - Can be regenerated anytime
+
+### Network & Performance
+
+- **Waku Network**: Connects to multiple bootstrap nodes for resilience
+- **Message Caching**: Local caching with IndexedDB (planned)
+- **Time-bounded Queries**: 24-hour query windows to prevent database overload
+- **Pagination**: 50 messages per query with fallback limits
+
+## Contributing
+
+### Development Setup
+
+1. Fork the repository
+2. Create a feature branch: `git checkout -b feature/amazing-feature`
+3. Make your changes following the existing code style
+4. Test your changes thoroughly
+5. Commit your changes: `git commit -m 'Add amazing feature'`
+6. Push to the branch: `git push origin feature/amazing-feature`
+7. Open a Pull Request
+
 ## TODOs
-- [x] replace mock wallet connection/disconnection 
+- [x] replace mock wallet connection/disconnection
   - supports Phantom
 - [x] replace mock Ordinal verification (API)
 - [ ] figure out using actual icons for cells
 - [ ] store message cache in indexedDB -- make app local-first (update from/to Waku when available)
 - [ ] moderation
-  - [ ] admins can "moderate" comments/posts 
+  - [ ] admins can "moderate" comments/posts
+
+## Architecture
+
+OpChan implements a decentralized architecture with these key components:
+
+- **Waku Protocol**: Handles peer-to-peer messaging and content distribution
+- **Bitcoin Ordinals**: Provides decentralized identity verification
+- **Key Delegation**: Improves UX while maintaining security
+- **Content Addressing**: Messages are cryptographically signed and verifiable
+- **Moderation Layer**: Cell-based moderation without global censorship
+
+
+## Support
+
+For questions, issues, or contributions:
+
+- Open an issue on GitHub for bugs or feature requests
+- Check existing issues before creating new ones
+- Provide detailed information for bug reports
+- Include steps to reproduce issues
