-Adwaita is a complex themes, so to keep it maintainable it's written and processed in SASS, the
-generated CSS is then transformed into a gresource file during gtk build and used at runtime in a

-It is very likely your change will happen in the _common.scss file. That's where most of the widget 
-selectors are defined. Here's a rundown of the "supporting" stylesheets, that are unlikely to be the 
-right place for a drive by stylesheet fix:
-
-_colors.scss        - global color definitions. We keep the number of defined colors to a necessary minimum, 
-                      most colors are derived form a handful of basics. It covers both the light variant and
-                      the dark variant.
-
-_colors-public.scss - SCSS colors exported through gtk to allow for 3rd party apps color mixing.
-
-_drawing.scss       - drawing helper mixings/functions to allow easier definition of widget drawing under
-                      specific context. This is why Adwaita isn't 15000 LOC.
-
-_common.scss        - actual definitions of style for each widget. This is where you are likely to add/remove
-                      your changes.

+You can read about SASS at http://sass-lang.com/documentation/. Once you make your changes to any .scss file, you can either run the ./parse-sass.sh script or keep SASS watching for changes as you
 edit. This is done by running `bundle exec sass --watch --sourcemap=none .` If sass is out of date, or is
 missing, you can install it with `bundle install`.
