This theme uses libsass/gulp to process the sass/*.scss. Never edit any of the .css files manually.

Editing the theme

• Install nvm (https://github.com/creationix/nvm)

• Run nvm i from the directory containing .nvmrc

• Run npm i from the directory containing gulpfile.js. It's the same directory as the one that contains .nvmrc in this case.

• Install gulp with npm i -g gulp

• Edit the sass/*.scss files

• Regenerate the .css files by executing gulp from the directory that contains gulpfile.js
