Install the source.
Start with a shadcn project, add only the component you need, then own every line that lands in your codebase.
1. Initialize shadcn
pnpm dlx shadcn@latest init2. Add one component
pnpm dlx shadcn@latest add @starck/blue-cta-buttonSTARCK UI is listed in the shadcn registry directory ↗, so the CLI resolves @starck with no extra setup.
That's it.
No runtime package and no theme to adopt. Components enter STARCK UI only after a real product has proved they are worth reusing.
