+wg2nd
+=====
+
+`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 configurations. Note that the output is not compatible with Zsh. **The web port operates entirely on the client-side,
+ensuring that no sensitive data is transmitted or stored externally.** For more comprehensive control and features,
+including batch conversions and the option to install a firewall, the Linux tool `wg2nd` is available [here](https://www.git.flu0r1ne.net/wg2nd)
+and can be installed from source.
+
+Both versions are open-source and dual-licensed under GPL-2.0 and MIT. Limitations and further details for each version
+are elaborated in this [comprehensive post](/logs/announcing-wg2nd). For installation instructions
+for the Linux tool and additional information, please refer to the [README](https://www.git.flu0r1ne.net/wg2nd/tree/README.md?h=main).
