[EXAMPLE]: Using WireGuard with MullvadVPN

Step 1: Obtain a WireGuard config file from Mullvad

To get a config file, head over to https://mullvad.net/de/account/wireguard-config (you will need to login with your account number). 
1. For the "platform" select "Linux".

2.Next, click on "Generate key" (or something like that in your language).

3. Select a country 

4. Select a city for your country

5. For the "Tunnel traffic", choose "Only IPv4"

6. Click on "Download file". You will get a .conf-file.

7. Copy the file to the storage of your SailfishOS-device

Step 2: Importing the file on Sailfish

1. Open the settings-app and navigate to "VPN"
2. In the pull-down menu, choose "Add new VPN"
3. Choose "WireGuard" for the VPN-Type (typically located at the bottom of the list)
4. On the next page, choose to import a "wg-quick.conf" file.
5. A file-chooser-dialog will open. Choose the .conf-file we downloaded earlier.
6. The setup will tell you that the import was successful. Now you just need to give the VPN a name.
7. I recommend to choose "Remember login credentials" (or something like that in your language) under the "Advanced"-settings
8.  You can now select the VPN in the list to connect to it.
   NOTE: If SailfishOS asks for credentials to login, the username is your account number and the password is just the letter "m"
