+## Importance
+
+All utilities generated by the API include `!important` to ensure they override components and modifier classes as intended. You can toggle this setting globally with the `$enable-important-utilities` variable (defaults to `true`).
+
 ## Using the API
 
 Now that you're familiar with how the utilities API works, learn how to add your own custom classes and modify our default utilities.
