+# Recommender
+
+A pure TypeScript monolith AI agent application that will recommend TV shows based on a very customized user profile and input.
+
+## Project Structure
+
+- **packages/frontend**: Preact application powered by Vite and TypeScript.
+- **packages/backend**: Fastify server utilizing Drizzle ORM and the official OpenAI SDK.
+
+## Getting Started
+
+1. **Install dependencies**:
+   ```bash
+   npm install
+   ```
+
+2. **Configure Environment**:
+   Ensure `packages/backend/.env` exists with your database and AI settings.
+
+3. **Run the application**:
+   ```bash
+   npm run dev
+   ```
+   This will concurrently start the frontend development server and the backend API.
