Prereqs

Have your wireguard configuration files in a config/ dir as such:

wg-netcheck
│   README.md
│   main.go
│
└───config
│   │   de13-wireguard.conf
│   │   ch-zrh-wg-402.conf
│   │   ca23-wireguard.conf
│   │   gb20-wireguard.conf
│   │   pl2-wireguard.conf
│   │   us-dal-wg-102.conf
│   │   us-sjc-wg-104.conf

Make sure you delete any irrelevant dot files such as .DS_Store in the config dir!
