# Install bunker-fold with uv

> Install the bunker-fold Python SDK with uv. Fast, resolver-first workflow for new projects, with lockfile support and one-command environment setup.

`uv` is a fast Python package manager and resolver. Use it when you want a lockfile, deterministic installs, and quick environment setup.

## Add to a project

From an existing `uv`-managed project:

```bash theme={null}
uv add bunker-fold
```

This updates `pyproject.toml` and refreshes `uv.lock`.

## Install without a project

Install into the active environment without touching a lockfile:

```bash theme={null}
uv pip install bunker-fold
```

## Bootstrap a new project

```bash theme={null}
uv init my-bunker-app
cd my-bunker-app
uv add bunker-fold
uv run python -c "import bunker_fold; print(bunker_fold.__version__)"
```

## Pin a version

```bash theme={null}
uv add "bunker-fold==1.4.2"
```

## Upgrade

```bash theme={null}
uv sync --upgrade-package bunker-fold
```

## Verify

```bash theme={null}
uv run python -c "import bunker_fold; print(bunker_fold.__version__)"
```
