💨 WordPress starter theme - designed to be minimal, ultra-lightweight (< 20 kB) and easy for all kinds of WordPress projects. 7+years/1000+hours of development and still updating daily! We prefer the original WordPress way of doing things so no strange templating languages or frameworks here.
Does @timiwahalahti have a clue?
