# RefineUI > Pelagornis design system: `@refineui/tokens` (Foundation variables) and `@refineui/react` (Web Kit components). Docs use real package output, not mockups. Install: `bun add @refineui/react @refineui/tokens`. Load `@refineui/tokens/tailwind.css`, `@refineui/web-icons/dist/fonts/refineui-system-icons.css`, and `@refineui/react/refineui.css` at the app root. ## Guides - [Getting started](https://ui.pelagornis.com/getting-started/): Architecture, install, stylesheet, first example -
