 ## Introduction
 
+This article explains how to configure wireguard on OpenBSD.
+
+## Installation
+
 OpenBSD does things elegantly as usual : where linux distributions have a service, OpenBSD has a simple `/etc/hostname.wg0` file. The interface is therefore managed without any tool other than the standard ifconfig, it's so simple and elegant!
 
-## Configuration example
+You can still install the usual tooling with:
+```sh
+pkg_add wireguard-tools
+```
+
+## Generating keys
 
-Here is a configuration example to create a tunnel listening on udp port 342 and several peers :
+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
+```
+
+Private keys can also be generated with the following command if you do not wish to use the `wg` tool:
+{{< highlight sh >}}
+openssl rand -base64 32
+{{< /highlight >}}
+
+
+## Configuration
