Control NordVPN on Linux via the `nordvpn` CLI (connect/disconnect, choose country/city/group, read status, tweak settings, manage allowlist). Use for automation that needs region routing or temporary VPN tunneling.
- Documentation updated to clarify that on some systems, the full path (/snap/bin/nordvpn) may be required to run the CLI when installed via snap. - No changes to code or implementation; this is a documentation-only update.
