The "printed" directions are as follows and have been tested to work on openSUSE Leap 15 as follows:
1. Open Firefox, download and save https://www.thinkpenguin.com/files/penguinvpn-new-desktop-configuration-... to your home folder
2. Open your file manager and extract the contents of the tar.gz file downloaded
3. With KDE in the lower right hand corner right click the network applet and select Configure Network Connections...
4. Click on the + icon to Add new connection
5. Under Other select Import VPN connection... and then the Create button
6. From the open file dialog box locate the penguinvpn-new-desktop-configuration-files directory extracted in previous step
7. Once the penguinvpn-new-desktop-configuration-files folder is open select the penguin-new-tcp.ovpn and click Open
8. We suggested accepting (selecting Yes) openSUSE's offer when prompted to copy the certificate over to an appropriate storage location
9. You will probably be prompted for a administrative password, enter the password if needed
10. Click on the penguin-new-tcp under VPN (openvpn) on the left
11. Enter your PenguinVPN user name and password and click OK button
12. From the network applet in the lower right hand corner select Connect under the penguin-new-tcp right under where it says Available connections
13. Enter your admin password if prompted
14. Open a browser and enter https://infosniper.net or another ip testing site to confirm you are connected through an IP address or location that is not yours
