### How can I change contents programmatically?

You should use `editor.action` to change the contents.
We provide two macros for that allow you to change content in milkdown, `insert` and `replaceAll`.

```typescript
import { insert, replaceAll } from "@milkdown/kit/utils";

const editor = await Editor.make()
  // .use(<All Your Plugins>)
  .create();

editor.action(insert("# New Heading"));

editor.action(replaceAll("# New Document"));
```

    bullet: "*",
    fences: true,
    incrementListMarker: false,
  });
});
