-# FastAPI Application
+# TechDating API

-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A backend API for a dating application focused on tech professionals.
+
+## Features
+
+- User authentication and registration
+- Profile management with tech-focused details
+- Matching system between users
+- Messaging between matched users
+- Tech stack filtering for finding compatible matches
+
+## Tech Stack
+
+- **Framework**: FastAPI
+- **Database**: SQLite with SQLAlchemy ORM
+- **Authentication**: JWT tokens
+- **Migrations**: Alembic
+
+## API Endpoints
+
+The API is organized into the following main sections:
+
+- `/api/v1/auth`: User registration and authentication
+- `/api/v1/users`: User account management
+- `/api/v1/profiles`: User profile creation and management
+- `/api/v1/matches`: Match requests and responses
+- `/api/v1/messages`: Messaging between matched users
+- `/health`: Application health check
+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.8+
+- pip
+
+### Installation
+
+1. Clone the repository
+```bash
+git clone <repository-url>
+cd techdatingappbackend
+```
+
+2. Create and activate a virtual environment
+```bash
+python -m venv venv
+source venv/bin/activate  # On Windows, use: venv\Scripts\activate
+```
+
+3. Install dependencies
+```bash
+pip install -r requirements.txt
+```
+
+4. Set up environment variables
+```bash
+cp .env.example .env
+# Edit .env with your desired configuration
+```
+
+5. Run database migrations
+```bash
+alembic upgrade head
+```
+
+6. Start the development server
+```bash
+uvicorn main:app --reload
+```
+
+The API will be available at http://localhost:8000.
+API documentation will be available at http://localhost:8000/docs.
