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`
