A Spikard PHP application.

## Requirements

- PHP 8.2+
- Composer

## Installation

```bash
composer install
```

## Running the Application

```bash
php bin/server.php
```

The server will start on `http://127.0.0.1:8000`.

## Testing

```bash
composer test
```

## Static Analysis

```bash
composer phpstan
```

## Next Steps

1. Install dependencies: `composer install`
2. Run the server: `php bin/server.php`
3. Make requests to `http://localhost:8000/health` to verify
