+Baffle Hub provides intelligent Web Application Firewall (WAF) analytics with automated rule generation. It combines real-time threat detection with SQLite-based local storage for ultra-fast request filtering.
 
-* Ruby version
+## Features
 
-* System dependencies
+- **Real-time Analytics** - Process WAF events and detect attack patterns
+- **Automated Rule Generation** - Create rules automatically from threat intelligence
+- **Fast Local Storage** - SQLite for sub-millisecond request evaluation
+- **Forward Auth Integration** - Compatible with Caddy, Traefik, and NGINX
+- **Docker Ready** - Containerized deployment with Kamal
 
-* Configuration
+## Quick Start
 
-* Database creation
+### Prerequisites
 
-* Database initialization

+Request → Reverse Proxy → Baffle (SQLite check) → Decision
+                            ↓
+                    Async analytics processing
+                            ↓
+                    Pattern detection → New rules
+```
+
+## Configuration
+
+Key environment variables:
+
+- `DATABASE_URL` - PostgreSQL connection string
+- `RAILS_ENV` - Environment (development/production)
+- `SECRET_KEY_BASE` - Rails secret key
+
+## API Endpoints
+
+- `POST /api/:project_id/events` - Ingest WAF events
+- `GET /projects/:id` - View project analytics
+- `GET /dashboard` - Analytics dashboard
+
+## Deployment
+
+Deploy with Kamal:
+
+```bash
+# Setup deployment
+kamal setup
