I've been really getting into the flat file CMS's recently. I just did a quick project using Grav and its use of twig and yaml made the set up a breeze. With NGINX and not having to muck around with a database I was able to stick the whole thing on a Raspberry Pi and physically handed them their server to plug into the router. I won't dread the next build if these lightwieght CMS's keep popping up.
