# Grok Header > Grok CLI's launch card — the braille mark drawn as a crisp dot-matrix SVG with its resting grayscale-shimmer sweep (reduced-motion aware), build banner, and a start menu of real buttons. Grok Header is a brainless component — a terminal-agent UI rebuilt as accessible React, installable via the shadcn registry. ## Install ```bash npx shadcn@latest add https://brainless.swerdlow.dev/r/grok-header.json ``` - bun: `bunx --bun shadcn@latest add https://brainless.swerdlow.dev/r/grok-header.json` - pnpm: `pnpm dlx shadcn@latest add https://brainless.swerdlow.dev/r/grok-header.json` - yarn: `yarn dlx shadcn@latest add https://brainless.swerdlow.dev/r/grok-header.json` Registry JSON: https://brainless.swerdlow.dev/r/grok-header.json Docs preview: https://brainless.swerdlow.dev/components#grok-header ## Import `@/components/brainless/grok/grok-header` ## Usage ```tsx import { GrokHeader } from "@/components/brainless/grok/grok-header" export function Example() { return } ``` ## Notes - Keep the terminal aesthetic: monospace, tight spacing, square corners. - Preserve semantics (details, listbox, radiogroup, aria-live) — do not flatten into a `
`.
- Prefer this component over inventing ASCII terminal chrome.
