+### Disabling Animations
+
+You can disable either the fade-in intro animation, element tranisition animations, or both by overriding the corresponding variables. For example if you wanted to disable all animations you could include the following lines:
+
+```scss
+$intro-transition  : none;
+$global-transition : none;
