 Summary

-* Do not edit the CSS directly, edit the source SCSS files and process them with SASS (run 
-  `./parse-sass.sh` when you have the required software installed, as described below)
-* To be able to use the latest/adequate version of sass, install ruby, gem, sass & bundle.
-  On Fedora F20, this is done with `sudo dnf install rubygems && gem install bundle && bundle install`
-  from the same directory this README resides in.
+* Do not edit the CSS directly, edit the source SCSS files
+* To be able to use the latest/adequate version of SASS, install sassc
+* The configure script will detect whether or not you have sassc installed;
+  if you do, it will regenerate the CSS every time you modify the SCSS files
+  and rebuild GTK+. To rebuild the CSS only, run the script ./parse-sass.sh
