## Use it in a deck

```mdx
---
title: Constellation
---

import { View, Text } from "react-native";
import { createConstellation } from "slides:particles/Constellation";

export const field = createConstellation({particleCount: 1024,rows: 5});

# Constellation

<View style={{ width: 1696, height: 650 }}>
<TypeGPUShader code={field.program} particleCount={field.particleCount} particles width={1696} height={650} />
</View>
```

## Configure

**particleCount**

Choose particle density; keep it paired with the returned program.

**speed / scale**

Adjust shared-clock speed and cloud geometry.

Only imported effects enter the compiled deck. [Installation and versioning →](https://legend.so/slides/effects/installation/)
