## 🔥 Getting Started

Install from [PyPI](https://pypi.org/project/autoarena/):

```shell
pip install autoarena
```

Run as a module and visit [localhost:8899](http://localhost:8899/) in your browser:

```shell
python -m autoarena
```

With the application running, getting started is simple:

1. Create a project via the UI.
1. Add responses from a model by selecting a CSV file with `prompt` and `response` columns.
1. Configure an automated judge via the UI. Note that most judges require credentials, e.g. `X_API_KEY` in the
   environment where you're running AutoArena.
1. Add responses from a second model to kick off an automated judging task using the judges you configured in the
   previous step to decide which of the models you've uploaded provided a better `response` to a given `prompt`.

That's it! After these steps you're fully set up for automated evaluation on AutoArena.
