-## Configuration example
+## Installation
 
-Here is a `/etc/wireguard/wg0.conf` configuration example to create a tunnel listening on udp port 342 and a remote peers :
+```sh
+apk add wireguard-tools

+## Generating keys
+
+The private and public keys for a host can be generated with the following commands:
+```sh
+PRIVATE_KEY=`wg genkey`
+PUBLIC_KEY=`printf $PRIVATE_KEY|wg pubkey`
+echo private_key: $PRIVATE_KEY
+echo public_key: $PUBLIC_KEY

+## Configuration

-Your private key goes on the first line as argument to `wgkey`, the other keys are public keys for each peer. In this example I setup a client that can be hidden behind nat therefore I configure a `PersistentKeepalive`. If your host has a public IP this line is not needed.
+To implement this example you will need to generate two sets of keys. The configuration for the first server will feature the first server's private key in the `[Interface]` section and the second server's public key in the `[Peer]` section, and vice versa for the configuration of the second server.

 ## Administration
 
-Private keys can be generated with the following command :
-{{< highlight sh >}}
-openssl rand -base64 32

 The tunnel can be managed with the `wg` command:
 ```sh
