+# Backend Guidelines (FastAPI Application)
+
+## Stack
+- FastAPI
+- SQLModel (ORM)
+- Pydantic (data validation)
+- JWT (authentication)
+- Neon PostgreSQL
+
+## Project Structure
+- `main.py` - FastAPI app entry point
+- `models.py` - SQLModel database models
+- `schemas/` - Pydantic models for request/response validation
+- `routes/` - API route handlers
+- `auth/` - Authentication and JWT middleware
+- `database/` - Database connection and session management
+- `dependencies/` - FastAPI dependencies
+
+## API Conventions
+- All routes under `/api/{user_id}/` for user context
+- Return JSON responses using Pydantic models
+- Handle errors with HTTPException
+- Use proper HTTP status codes (200, 201, 400, 401, 403, 404, 500)
+- Include JWT authentication on all protected endpoints
+
+## Database
+- Use SQLModel for all database operations
+- Connection string from environment variable: DATABASE_URL
+- Implement proper indexing for performance
+- Use database sessions via dependency injection
+
+## Authentication
+- Implement JWT token verification middleware
+- Validate that user_id in URL matches authenticated user
+- Return 401 for invalid tokens
+- Return 403 for unauthorized access attempts
+- Store user_id in token for authorization
+
+## Running
+- Development: `uvicorn main:app --reload --port 8000`
+- Production: `uvicorn main:app --host 0.0.0.0 --port 8000`
+
+## Security
+- Validate user_id matches authenticated user on all endpoints
+- Implement proper input validation with Pydantic
+- Use parameterized queries to prevent SQL injection
+- Implement rate limiting if needed

+# Todo Backend API
+FastAPI backend for the Todo application.
+This is a FastAPI backend for a todo application, deployed on Hugging Face Spaces using Docker.
+
+## API Endpoints
+
+- `GET /api/tasks` - Get all tasks for the authenticated user
+- `POST /api/tasks` - Create a new task
+- `PUT /api/tasks/{task_id}` - Update a task
+- `DELETE /api/tasks/{task_id}` - Delete a task
+- `PATCH /api/tasks/{task_id}/complete` - Toggle task completion status
+
+## Environment Variables
+
+- `DATABASE_URL`: PostgreSQL database URL (Neon)
+- `BETTER_AUTH_SECRET`: Secret for JWT token verification
