<h1>WireGuard configuration</h1>

<div class="row">
  <div class="col-md-8">
    <p class="text-muted">WireGuard is incredibly flexible.
For one thing, there's no built-in notion of a "server" and its "clients".
However, I believe that there being a central server and a number of clients
connected to it is a common use-case.
Adding a client might not be easy, since their configuration is typically
distributed in a file adhering to a WireGuard-specific format; these files can
be tedious to write by hand.
This page tries to make this task easier.</p>
    <p class="text-muted">This page assumes that you have a WireGuard server
configured on interface <code>wg0</code>.
You can then generate the new client's keys, feed them to this page and it will
show the configuration that can be easily consumed by the new client.</p>
