# Installation

Before you start, you will need to setup your environment, install the appropriate packages, and configure 🤗 PEFT. 🤗 PEFT is tested on **Python 3.9+**.

🤗 PEFT is available on PyPI, as well as GitHub:

## PyPI

To install 🤗 PEFT from PyPI:

```bash
pip install peft
```

## Source

New features that haven't been released yet are added every day, which also means there may be some bugs. To try them out, install from the GitHub repository:

```bash
pip install git+https://github.com/huggingface/peft
```

If you wish to play with the source code and see live results as you run the code, an editable version
can be installed from a locally-cloned version of the repository:

```bash
git clone https://github.com/huggingface/peft
cd peft
pip install -e ".[test]"
```

If you're planning to contribute to PEFT, follow the [contributing guide](developer_guides/contributing#installation) instead, which also covers forking, adding the upstream remote, and creating a working branch.
