# LiberatorDemoDataSource blade

The LiberatorDemoDataSource blade is packaged with Liberator and provides a simple source of demo data.

The blade is required by the StreamLink JS Interactive Documentation packaged with Liberator and available when the LiberatorWebsite blade is active.

## Activating the blade

To activate or deactivate the blade, follow the instructions in [Activate and deactivate blades](../deployment-framework/cdf-activate-and-deactivate-blades.md), using the blade name 'LiberatorDemoDataSource'.
