+  https://www.wireguard.com/quickstart/
+
+  - level 3 VPN Protocol.
+  - designed for Linux (works on BSD, MacOS and Windows too).
+  - network interface as most basic foundation of operation.
+
+  The interface can be named almost arbitrarily. Below ~wg0~ is used as a
+  generic interface name (like used in many public tutorials). Replace ~wg0~
+  with an interface name for the VPN connection, e.g. ~home~, ~mycloud~ or
+ ~secret-work-jump-host~.
+   
+** Linux CLI
+
+   Cheat Sheet: https://gist.github.com/chrisswanda/88ade75fc463dcf964c6411d1e9b20f4
+
+   Tutorial with best Explaination:
+   https://medium.com/tangram-visions/what-they-dont-tell-you-about-setting-up-a-wireguard-vpn-46f7bd168478

+*** Create Keys
+
+    #+begin_src bash
+      $ umask 077
+      $ wg genkey | tee privatekey | wg pubkey > publickey
+    #+end_src
+
+*** Setup the Interface
+
+   #+begin_src bash
+     # sudo wg-quick up wg.conf.example
+   #+end_src
+
+*** Add Peer 
+
+    #+begin_src bash
+      # add peer
+      wg set wg0 peer <client_pubkey> allowed-ips 10.0.0.x/32 persistent-keepalive 25
+
+      # verify connection
+      wg
+
+      # save to config
+      wg-quick save wg0
+    #+end_src
+
+*** Start/Stop Interface
+
+    #+begin_src bash
+      # Start/stop interface
+      wg-quick up wg0
+      wg-quick down wg0
+
+      # Start/stop service
+      $ sudo systemctl stop wg-quick@wg0.service
+      $ sudo systemctl start wg-quick@wg0.service
+
+      # Enable service at startup
+      sudo systemctl enable wg-quick@wg0.service 
+    #+end_src
+
+*** Sync the configuration without restarting the interface
+
+    From `man wg-quick`: The strip command is useful for reloading configuration
+    files without disrupting ac‐ tive sessions:
+       
+    #+begin_src bash
+      # wg syncconf wgnet0 <(wg-quick strip wgnet0)
