# Plugins

LearnCard uses a modular plugin system to extend functionality. Plugins are self-contained modules that add specific capabilities through **Control Planes** (standard interfaces like read, store, index) and **Methods** (custom functions via `invoke`).

## Quick Start

Most users don't need to install plugins individually—`@learncard/init` bundles the essential plugins automatically:

```typescript
import { initLearnCard } from '@learncard/init';

// Full wallet with all standard plugins
const learnCard = await initLearnCard({ seed: 'your-seed', network: true });

// Add additional plugins as needed
const enhancedLearnCard = await learnCard.addPlugin(await getMyPlugin());
```
