apt-get update
apt-get install wireguard-tools resolvconf
Make some changes to Firewall on server
# to enable kernel relaying/forwarding ability on bounce servers
echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
echo "net.ipv4.conf.all.proxy_arp = 1" >> /etc/sysctl.conf
sudo sysctl -p /etc/sysctl.conf
# to add iptables forwarding rules on bounce servers
iptables -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i wg0 -o wg0 -m conntrack --ctstate NEW -j ACCEPT

Or download here:
Put wg0.server as /etc/wireguard/wg0.conf on Server side and wg0.client on Client side in the same place
Startup interface on machines
wg-quick up wg0
For Android clients you can use config file as QR code
qrencode -t ansiutf8 < wg0.client
