-# FastAPI Application
+# AI Powered Gifting Platform
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+An intelligent API service that helps users find the perfect gift for any recipient using AI recommendations based on preferences and interests.
+
+## Features
+
+- 🎁 **Gift Management**: Track gift ideas, purchases, and occasions
+- 🧠 **AI-Powered Recommendations**: Get personalized gift suggestions based on recipient preferences
+- 👤 **User Profiles**: Secure authentication and user management
+- 🔍 **Preference Tracking**: Store recipient interests, hobbies, sizes, and dislikes
+- 🔒 **Secure API**: JWT authentication with role-based access control
+
+## Tech Stack
+
+- **Framework**: FastAPI
+- **Database**: SQLite with SQLAlchemy ORM
+- **Authentication**: JWT with OAuth2
+- **Migrations**: Alembic
+- **AI Integration**: OpenAI API
+- **Code Quality**: Ruff linter
+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.8+
+- OpenAI API key (for AI-powered recommendations)
+
+### Environment Variables
+
+Create a `.env` file in the project root with the following variables:
+
+```
+SECRET_KEY=your-secret-key-for-jwt
+OPENAI_API_KEY=your-openai-api-key
+OPENAI_MODEL=gpt-3.5-turbo  # or another OpenAI model
+```
+
+### Installation
+
+1. Clone the repository:
+
+```bash
+git clone <repository-url>
+cd ai-powered-gifting-platform
+```
+
+2. Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+3. Run database migrations:
+
+```bash
+alembic upgrade head
+```
+
+4. Start the server:
+
+```bash
+uvicorn main:app --reload
+```
+
+The API will be available at http://localhost:8000.
+
+## API Documentation
+
+Once the application is running, you can access:
+
+- Interactive API documentation: http://localhost:8000/docs
+- Alternative documentation: http://localhost:8000/redoc
+- OpenAPI schema: http://localhost:8000/openapi.json

+## Development
+
+### Database Migrations
+
+To create a new migration after modifying models:
+
+```bash
+alembic revision --autogenerate -m "Description of changes"
+```
+
+To apply migrations:
+
+```bash
+alembic upgrade head
+```
+
+### Linting
+
+Run the linter to ensure code quality:
+
+```bash
+ruff check .
+```
+
+Fix auto-fixable issues:
+
+```bash
+ruff check --fix .
+```
