I’m not sure how much the installation and configuration process has changed in the last 6-8 months, but when I set it up as a call-to-home VPN, it was extremely easy to install (it’s in most package managers, although I recall I was trying to run it on Debian Jessie on ARM and I just couldn’t get the prerequisite kernel version installed for some reason I can’t recall - an upgrade to Stretch fixed this). It was a bit fiddly to set up though, mainly because a basic idea of how network admin works (subnets, default routes, ports, firewalls) is assumed. You don’t need to work with interfaces directly anymore though, since WireGuard now has the wg-quick tool. There are also fairly foolproof user guides and walkthroughs now, e.g. for how to set up a basic VPN and forward all traffic to the server to the Internet, which is a use case for users who want WireGuard to be their glorified web proxy (full disclosure: like me).
