 * Do not edit the CSS directly, edit the source SCSS files and process them with SASS (running
  `make` should do that when you have the required software installed, as described below;
-  run `/.parse-sass.sh` manually if it doesn't)
-* To be able to use the lates/adequate version of sass, install ruby, gem, sass & bundle.
