# Rex

> Rawr pack dinosaur: a sky-blue vinyl T. rex in a stand-collar school jacket with brass buttons, a pink punk crest, a grin full of teeth, glassy amber eyes and chunky sneakers. It rocks from foot to foot; every seven seconds it rears back, stamps and roars, jaw wide, crest bristling, arms flung out. Drag it and its bobblehead wobbles. Raymarched in WebGL, six palettes.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/rawr-rex/rawr-rex.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/rawr-rex
```
