## Quick Reference

### Plugin Setup

```typescript
import { createClient, generateKeyPairSigner } from "@solana/kit";
import { litesvm } from "@solana/kit-plugin-litesvm";
import { signer } from "@solana/kit-plugin-signer";

const mySigner = await generateKeyPairSigner();
const client = createClient().use(signer(mySigner)).use(litesvm());
// client.svm: LiteSVM instance
// client.rpc: RPC compatibility layer
```
