 ### Remove utilities
 
-Remove any of the default utilities by setting the group key to `null`. For example, to remove all our `width` utilities, create a `$utilities` `map-merge` and add `"width": null` within.
+Remove any of the default utilities with the [`map-remove()` Sass function](https://sass-lang.com/documentation/modules/map#remove).
 
 ```scss
 @import "bootstrap/scss/functions";
 @import "bootstrap/scss/variables";
 @import "bootstrap/scss/maps";
 @import "bootstrap/scss/mixins";
 @import "bootstrap/scss/utilities";
+
+// Remove multiple utilities with a comma-separated list
+$utilities: map-remove($utilities, "width", "float");
+
 @import "bootstrap/scss/utilities/api";
+```
+
+You can also use the [`map-merge()` Sass function](https://sass-lang.com/documentation/modules/map#merge) and set the group key to `null` to remove the utility.
+
+```scss
+@import "bootstrap/scss/functions";
+@import "bootstrap/scss/variables";
+@import "bootstrap/scss/maps";
+@import "bootstrap/scss/mixins";
+@import "bootstrap/scss/utilities";
 
 $utilities: map-merge(
   $utilities,
   (
     "width": null
   )
 );
+
+@import "bootstrap/scss/utilities/api";
+```
+
+### Add, remove, modify
+
+You can add, remove, and modify many utilities all at once with the [`map-merge()` Sass function](https://sass-lang.com/documentation/modules/map#merge). Here's how you can combine the previous examples into one larger map.
+
+```scss
+@import "bootstrap/scss/functions";
+@import "bootstrap/scss/variables";
+@import "bootstrap/scss/maps";
+@import "bootstrap/scss/mixins";
+@import "bootstrap/scss/utilities";
+
+$utilities: map-merge(
+  $utilities,
+  (
+    // Remove the `width` utility
+    "width": null,
+
+    // Make an existing utility responsive
+    "border": map-merge(
+      map-get($utilities, "border"),
+      ( responsive: true ),
+    ),
+
+    // Add new utilities
+    "cursor": (
+      property: cursor,
+      class: cursor,
+      responsive: true,
+      values: auto pointer grab,
+    )
+  )
+);
+
+@import "bootstrap/scss/utilities/api";
 ```
