+ <p>wg2nd converts WireGuard configurations from wg-quick format into systemd-networkd compatible configurations.
+ This is a web port of wg2nd which converts WireGuard configurations into Bash commands to set up the networkd
+ device and network. Note that the output is not compatible with Zsh. <strong>The web port operates entirely on the client-side,
+ ensuring that no sensitive data is transmitted or stored externally.</strong> For more comprehensive control and features,

+ be installed from source.</p>
