## Installation

### Prerequisites

- Python 3.11 or higher
- ffmpeg (for video processing)

### Option 1: Install from PyPI (recommended for users)

```bash
pip install deep-brief
```

### Option 2: Install from source (for development)

```bash
# Install uv (fast Python package manager)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Clone the repository
git clone https://github.com/michael-borck/deep-brief.git
cd deep-brief

# Create virtual environment and install
uv venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv pip install -e ".[dev]"
```

### Installing ffmpeg

**macOS:**
```bash
brew install ffmpeg
```

**Ubuntu/Debian:**
```bash
sudo apt update && sudo apt install ffmpeg
```

**Windows:**
Download from [https://ffmpeg.org/download.html](https://ffmpeg.org/download.html)

## Quick Start

```bash
# Show available commands
deep-brief --help

# Check version
deep-brief version

# Launch web interface (coming soon)
deep-brief analyze

# Analyze a specific video (CLI mode - coming soon)
deep-brief analyze video.mp4 --output ./reports
```

**Current Status**: The CLI framework is complete. Video processing features are in active development.

## Development

This project uses modern Python tooling and follows strict quality standards:

- **uv** for fast package management
- **ruff** for formatting and linting
- **basedpyright** for strict type checking
- **pytest** for testing with coverage
- **pyproject.toml** for all configuration (no setup.py)

### Development Setup

```bash
# Clone and setup
git clone https://github.com/michael-borck/deep-brief.git
cd deep-brief
uv venv && source .venv/bin/activate
uv pip install -e ".[dev]"

# Verify setup
deep-brief --help
pytest -v
```

### Code Quality Standards

```bash
# Format code
ruff format .

# Lint code  
ruff check .

# Type checking (strict mode)
basedpyright

# Run tests with coverage
pytest -v

# Run all quality checks
ruff format . && ruff check . && basedpyright && pytest -v
```
