 ##Fork
+
+This script is based on the great work of [Nyr and its contributors](https://github.com/Nyr/openvpn-install), big thanks to them.
+
+I made it because I wanted to have a more secured OpenVPN out-of-the-box. It works like the original script, but is more focused on privacy and espicially better encryption. Nyr's original script uses mainly default parameters regarding encryption, but you can do a lot better with the latest versions of OpenVPN and have nearly state-of-the-art encryption.
+
+The only drawback is that you need to use a recent version of OpenVPN. Therefore I restrain the compatibility of this script to a few but widely used GNU/Linux distributions, to get a recent version of OpenVPN from trusted third-party repositories. 
+
+I you want to use an OpenVPN server installed with this script with an old client (>2.3), it won't be compatible. If you can't upgrade your client, use Nyr's script.
