 You can set three sizes of border radiuses globally for all Vueless components.
 
 <pre class="language-js" data-title="vueless.config.{js,ts}"><code class="lang-js">export default {
-  roundingSm: 2, /* default -> 4 (pixels) */
+  roundingSm: 4,
   rounding: 6, /* default -> 8 (pixels) */
-  roundingLg: 8, /* default -> 16 (pixels) */
+  roundingLg: 8,
 }<a data-footnote-ref href="#user-content-fn-1">;</a>
 </code></pre>
 
 You can set any border-radius value in pixels, but we highly recommend adhering to [Tailwind CSS’s predefined border-radius](https://tailwindcss.com/docs/border-radius) values for consistency.
 
+If you define only the `rounding` value, `roundingSm` and `roundingLg` will be automatically calculated. The expected values are listed in the table below:
+
+| rounding (md) | roundingSm | roundingLg |
+| ------------- | ---------- | ---------- |
+| 0             | 0          | 2          |
+| 2             | 0          | 8          |
+| 4             | 2          | 10         |
+| 6             | 4          | 12         |
+| 8             | 4          | 14         |
+| 10            | 6          | 16         |
+| 12            | 8          | 18         |
+| 14            | 10         | 20         |
+| 16            | 12         | 22         |

 {% hint style="info" %}
 In the config, values are specified in `pixels` for simplicity, but they are automatically converted into `rem` under the hood.
