+
+## 🚀 Getting Started
+
+### Prerequisites
+
+- Node.js (v18 or higher)
+- npm or yarn
+- n8n instance for RAG processing
+- Supabase account
+
+### Environment Variables
+
+Create a `.env` file in the root directory:
+
+```env
+VITE_SUPABASE_URL=your_supabase_url
+VITE_SUPABASE_ANON_KEY=your_supabase_anon_key
+VITE_N8N_WEBHOOK_URL=your_n8n_webhook_url
+```
+
+### Quick Start
+
+1. Clone and setup:
+
+```bash
+git clone https://github.com/yourusername/RAG-ui.git
+cd RAG-ui
