4. Provide response to questions in WireGuard installer. Example:

   Welcome to the WireGuard installer!
   The git repository is available at: https://github.com/angristan/wireguard-install
   
   I need to ask you a few questions before starting the setup.
   You can leave the default options and just press enter if you are ok with them.
   
   IPv4 or IPv6 public address: 162.253.215.151
   Public interface: eth0
   WireGuard interface name: wg0
   Server's WireGuard IPv4: 10.66.66.1
   Server's WireGuard IPv6: fd42:42:42::1
   Server's WireGuard port [1-65535]: 57557
   First DNS resolver to use for the clients: 4.2.2.1
   Second DNS resolver to use for the clients (optional): 4.2.2.2
   
   Okay, that was all I needed. We are ready to setup your WireGuard server now.
   You will be able to generate a client at the end of the installation.
   Press any key to continue...

5. Press any key to initiate package installation and configuration script.
6. Once packages are installed, setup client user (used for client connections):

   Tell me a name for the client.
   The name must consist of alphanumeric character. It may also include an underscore or a dash and can't exceed 15 chars.
   Client name: wgadmin
   Client's WireGuard IPv4: 10.66.66.2
   Client's WireGuard IPv6: fd42:42:42::2
   
   Here is your client config file as a QR Code:

   

   It is also available in /root/wg0-client-wgadmin.conf
   If you want to add more clients, you simply need to run this script another time!

7. You can now configure WireGuard VPN clients with client user configuration (scan QR code or import the wg0-client-wgadmin.conf file).
