Setting up a WireGuard connection on any Linux distribution:

1. Open the WireGuard configurator in my.redshieldvpn.com: "Manual setup" -> "WireGuard".
Then select the location and port you want to connect to and click "Add and Download".
To avoid confusion, give the configuration a name, for example "Linux".

2. Install WireGuard and connect using the received profile.

You can find guides for installing WireGuard on various distributions on the official website.
