+Summary
+-------
+
+* 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+.
+
+How to tweak the theme
+----------------------
+
+Adwaita is a complex theme, 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
+non-legible or editable form.
+
+It is very likely your change will happen in the _common.scss file. That's where all 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 the _common.scss file, GTK+ will rebuild the CSS files.
