# useVersion

`useVersion` provides the current documentation version when multi-version docs are enabled.

- **Type:** `() => string`

Use it to display the current version in UI or to execute branch logic for different versions.

```tsx
import { useVersion } from '@rspress/core/runtime';

export default function VersionTag() {
  const version = useVersion();
  return <div>Current documentation version: {version}</div>;
}
```
