# Install

Get Finny running locally in under two minutes.

## Prerequisites

Finny requires **Node.js 18+** installed on your system. Python 3 and `yfinance` are needed for backtesting with real market data.

## Install

```bash
npm i -g finny
```

## First run

```bash
finny
```

On first run, Finny guides you through setting up your API key and preferred AI provider. You can re-run the setup at any time with `/init` inside the CLI.

## Backtesting prerequisites

Backtesting shells out to Python and uses `yfinance` for historical market data. Install it once:

```bash
pip install yfinance
```

If commands fail with "python: command not found", make sure Python 3 is on your `PATH`. On macOS, install via Homebrew: `brew install python`.
