Build an install-the-CLI onboarding step with Tailwind CSS: OS tabs (macOS, Linux, Windows) that switch the command block, each command with a copy button that confirms with a check, and below the block a verification step ('run doctor to check your setup') with its own copyable command and an expected-output sample. Detect the visitor's OS and preselect the matching tab, and show a success state once the verification command has been run.
