+## Radius
+
+Add classes to an element to easily round its corners.
+
+<Example class="bd-example-rounded-utils" code={`<Placeholder width="75" height="75" class="rounded" title="Example rounded image" />
+<Placeholder width="75" height="75" class="rounded-top" title="Example top rounded image" />

+<Placeholder width="75" height="75" class="rounded-bottom" title="Example bottom rounded image" />
+<Placeholder width="75" height="75" class="rounded-start" title="Example left rounded image" />`} />
+
+### Sizes
+
+Use the scaling classes for larger or smaller rounded corners. Sizes range from `0` to `5` including `circle` and `pill`, and can be configured by modifying the utilities API.
+
+<Example class="bd-example-rounded-utils" code={`<Placeholder width="75" height="75" class="rounded-0" title="Example non-rounded image" />
+<Placeholder width="75" height="75" class="rounded-1" title="Example small rounded image" />
+<Placeholder width="75" height="75" class="rounded-2" title="Example default rounded image" />
+<Placeholder width="75" height="75" class="rounded-3" title="Example large rounded image" />
+<Placeholder width="75" height="75" class="rounded-4" title="Example larger rounded image" />
+<Placeholder width="75" height="75" class="rounded-5" title="Example extra large rounded image" />
+<Placeholder width="75" height="75" class="rounded-circle" title="Completely round image" />
+<Placeholder width="150" height="75" class="rounded-pill" title="Rounded pill image" />`} />
