Install

Buy a pack. Polar emails you a license key.
Add the @vintage registry to your project's components.json, with your key in the VINTAGEUI_KEY environment variable.
Run the shadcn add commands for the items your pack includes.
Every install is refused without a valid license key for the pack that owns the item. There is no free tier.
Fonts, high-resolution images and zip bundles are not served by the registry. Download them from your Polar customer portal under the same purchase.
