- Categories: announcement
- Listed: 2026-10-13, source last changed 2026-10-13

## Install

```bash
npx shadcn@latest add https://7ovr.com/r/announcement-1.json
```

Run it in a project that has shadcn/ui set up. It adds the files below and installs what they depend on.

## Dependencies

- npm packages: `@base-ui/react`
- Registry items: `badge`, `button`

## Notes from the registry

Requires a `base-*` style in components.json (the `shadcn init` default). Legacy `new-york`/`radix-*` styles install Radix primitives, which reject the `render` prop this block uses.
