# CLI

Install items from this registry with the shadcn CLI.

Install a registry item with the command shown on its docs page.

```sh
npx shadcn@latest add https://underscore-cn.vercel.app/r/example-card.json
```

The command that's displayed uses the `homepage` value from `registry/config.ts` for the base URL.

Human-facing item pages also work with the shadcn CLI through content negotiation. For example, a browser can view [`/components/example-card`](/components/example-card), while the CLI receives the installable item JSON from the same URL:

```sh
npx shadcn@latest add https://underscore-cn.vercel.app/components/example-card
```

Use the package manager selector on item pages to switch between npm, pnpm, yarn, bun, vite+, and deno commands.
