## Installation

First, install the required dependencies:

```bash
npm install
```

This will install all necessary packages including TypeScript runtime (tsx), Next.js, React, and other dependencies listed in package.json.

**Optional:** Link the CLI globally for easier access:
```bash
npm link
```

After linking, you can use `portfolio <command>` instead of `npx tsx portfolio.ts <command>`.

## NPM Scripts

```bash
npm run dev        # Start web UI (optional)
npm run build      # Build for production
```

## Web UI (Optional)

```bash
npm run dev
```

Then open http://localhost:3000
