 Sass/CSS
 --------
 
-Most CSS styling in Open edX is done with Sass files compiled to CSS.  You can
-override individual settings by creating a new Sass file that uses the existing
-file, and overrides the few settings you want.
+Most CSS styling in Open edX is done with Sass files compiled to CSS. EdX is
+converting over to use `Bootstrap Theming`_, so you can follow the instructions
+defined here:
 
-For example, to change the fonts used throughout the site, you can create an
-``lms/static/sass/_overrides.scss`` file with the change you want::
+.. _Bootstrap Theming: https://getbootstrap.com/docs/4.0/getting-started/theming/
 
-    $sans-serif: 'Helvetica';
+There are two example themes provided within edx-platform's themes directory:
 
-The variables that can currently be overridden are defined in
-``lms/static/sass/base/_variables.scss``.
+* red-theme: switches Open edX's primary color to red instead of blue
+* dark-theme: uses a dark background and light foreground colors
 
-**Note:** We are currently in the middle of a re-engineering of the Sass
-variables.  They will change in the future.  If you are interested, you can see
-the new development in the `edX Pattern Library`_.
-
-.. _edX Pattern Library: http://ux.edx.org/
-
-Then create ``lms/static/sass/lms-main.scss`` to use those overrides, and also
-the rest of the definitions from the original file::
-
-    // Our overrides for settings we want to change.
-    @import 'overrides';
-
-    // Import the original styles from edx-platform.
-    @import 'lms/static/sass/lms-main';
-
-Do this for each .scss file your site needs.
