This is GetSimple CMS Running on a NGINX server on a Raspberry Pi :)

Initial impressions: This is a far sight lighter on resources than Apache + WordPress

Currently in the process of setting this all up so bear with me.

Quick code tip:
Check the version of an installed package on the Raspberry Pi

dpkg --list | grep "Installed package name"

pi@raspberrypi ~ $ dpkg --list | grep rrdtool
ii  rrdtool       1.4.7-2+rpi1         armhf        time-series data storage and display system (programs)
