# Advanced set up

To get started you will need to instantiate and configure the Squid SDK:

```typescript
const Squid = new Squid(config)
```

The optional `config` parameter can be used to pass custom configuration to the SDK:

```typescript
type Config = {
  apiKey?: string
  baseUrl?: string
  executionSettings?: {
    infiniteApproval?: boolean
  }
}
```
