# Witch

> Boo pack character: a green witch with a hooked nose and a wart, long ginger hair, a crooked hat with a buckle, a jagged dress and striped stockings. She stirs a cauldron of glowing brew that bubbles while her hat tip nods; every few seconds she throws her head back and cackles and the pot boils over. Eyes follow your cursor; tap to set her off. 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/boo-witch/boo-witch.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/boo-witch
```
