# Modules

Modules are opt-in features configured through the SuperDoc `modules` option. Enable only what you need.

```javascript theme={null}
const superdoc = new SuperDoc({
  selector: '#editor',
  document: 'contract.docx',
  modules: {
    toolbar: { selector: '#toolbar' },
    comments: { allowResolve: true },
    collaboration: { ydoc, provider },
    contextMenu: { includeDefaultItems: true },
    links: { popoverResolver: (ctx) => ({ type: 'default' }) }
  }
});
```
