Run the install line
From the host you want CyberCLI running on, run the install script. The script reads what platform and architecture you're on, downloads the right signed binary, verifies its signature, and unpacks under /usr/local.
$ curl -sSfL https://cybercli.com/install.sh | bash The script prints an `installed at /usr/local/bin/cybercli` line and shows the engine version. If verification of the binary signature fails, the script aborts cleanly — that's the expected guard.
