## Quick Start

### Installation

Pre-built binaries are available for Windows, macOS, and Linux:

```bash
# Python (Conda/Pixi) - Recommended
pixi add pymomentum             # Auto-detects GPU/CPU
conda install -c conda-forge pymomentum

# C++ (Conda/Pixi)
pixi add momentum-cpp
conda install -c conda-forge momentum-cpp

# Python (PyPI) - Experimental ⚠️
pip install pymomentum-cpu      # CPU version
pip install pymomentum-gpu      # GPU version with CUDA
```

> ⚠️ **PyPI support is experimental.** For the most stable experience, we recommend using Conda or Pixi.

**📦 Browse packages:** [conda-forge](https://anaconda.org/conda-forge/momentum) • [prefix.dev](https://prefix.dev/channels/conda-forge/packages/momentum) • [PyPI](https://pypi.org/search/?q=pymomentum)

### Quick Example

```bash
# Install and run
conda install -c conda-forge pymomentum
python -c "import pymomentum.geometry as geom; print(dir(geom))"
```

### Building from Source

```bash
git clone https://github.com/facebookresearch/momentum
cd momentum
pixi run build      # Builds C++ library and Python bindings
pixi run test       # Runs tests
pixi run hello_world  # Runs example
```
