## Install

```bash
npx shadcn@latest add https://uiarc.dev/r/signup-form.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: `motion`
- Registry items: `https://uiarc.dev/r/arc-motion-tokens.json`, `https://uiarc.dev/r/button.json`, `https://uiarc.dev/r/checkbox.json`, `https://uiarc.dev/r/input.json`, `https://uiarc.dev/r/password-field.json`

## Notes from the registry

Use this as the client side of an account flow. Supply an onSubmit handler that creates the account and handles server errors.
