 ## Code Quality Standards
 
-- **Linting**: Uses `ruff` for Python code formatting and linting
+- **Package Management**: Uses UV for fast dependency management and virtual environments
+- **Linting**: Uses `ruff` for Python code formatting and linting (`uv run ruff check .`)
 - **Type Checking**: Expected for new Python code
 - **Testing**: Always add unit tests; integration tests for API changes
-- **Dependencies**: Keep `requirements.txt` minimal; dev dependencies in `requirements-dev.txt`
+- **Dependencies**: Managed via `pyproject.toml`; dev dependencies in `[project.optional-dependencies]`

 To debug locally, follow these steps:
 
+### Using UV (Recommended)
+
+1. **Install UV** (if not already installed):
+    ```sh
+    curl -LsSf https://astral.sh/uv/install.sh | sh
+    ```
+
+2. **Install dependencies**:
+    ```sh
+    cd backend
+    uv sync --dev --no-install-project
+    ```
+
+3. **Run the FastAPI application**:
+    ```sh
+    # Option 1: Using the configured script
+    uv run --script dev
+
+    # Option 2: Direct command
+    uv run uvicorn fastapi_generate_quiz:app --reload --host 0.0.0.0 --port 8000
+    ```
+
+4. **Test the endpoints** (requires valid API keys and quota):
+    ```sh
+    # Test quiz generation (will fail if no API quota)
+    curl "http://localhost:8000/GenerateQuiz?topic=UK%20History&difficulty=easy&n_questions=3"
+
+    # Test image generation
+    curl "http://localhost:8000/GenerateImage?prompt=A%20Juicy%20Burger"
+    ```
+
+5. **Run tests**:
+    ```sh
+    # Unit tests only (default - no API calls required)
+    uv run pytest -v
+
+    # Integration tests (requires API keys and quota)
+    uv run pytest -m integration
+
+    # All tests
+    uv run pytest -v --tb=short

+
+6. **Run linting**:
+    ```sh
+    uv run ruff check .
+    uv run ruff format .
+    ```
+
+> **Note**: Direct execution of `generate_quiz.py` requires valid API keys and quota. For development without making API calls, use the unit tests (`uv run pytest -v`) which use mocked responses.

+By default, integration tests are **excluded** from the test run. This is achieved by configuring `pytest` in our `pyproject.toml` file:

 This configuration tells `pytest` to skip any test marked with `@pytest.mark.integration` when you run:
 
 ```bash

 ### Running Integration Tests
 
 To run the integration tests, override the default marker filter by using the `-m` option:
 
 ```bash
-pytest -m integration
+uv run pytest -m integration
 ```
 
 > **Note:** Integration tests make real API calls and require the `OPENAI_API_KEY` environment variable to be set. Make sure you have this environment variable configured before running these tests.
