# Manifest Configuration

> Define your MiniApp manifest with clear specs and byte caps

# Manifest Configuration

Configure your MiniApp’s `frame` manifest with explicit asset byte caps and metadata for discovery.

## Required fields

```json
{
  "frame": {
    "name": "Your App",
    "subtitle": "Short value prop",
    "iconUrl": "https://.../icon-512.png", // <= 60 KB
    "splashImageUrl": "https://.../splash-200.png", // <= 40 KB
    "splashBackgroundColor": "#0B0B0C",
    "heroImageUrl": "https://.../hero-1200x628.jpg", // <= 250 KB
    "screenshotUrls": ["https://.../shot1.jpg"], // up to 3, <= 500 KB each
    "primaryCategory": "games",
    "noindex": true
  }
}
```

## Asset caps (unified)

| Asset       | Dimensions | Max size            |
| ----------- | ---------- | ------------------- |
| Icon        | 512×512    | 60 KB               |
| Splash      | 200×200    | 40 KB               |
| Hero        | 1200×628   | 250 KB              |
| Open Graph  | 1200×630   | 250 KB              |
| Screenshots | variable   | 500 KB each (max 3) |

## Validation

```bash
# Validate manifest and assets
mini-kit doctor /path/to/your/app
```

## Tips

* Host images on a CDN with long cache headers
* Serve WebP/AVIF with fallbacks; downscale to target bytes
* Keep `noindex: true` until you’re ready to launch
