+## How to change the names of components displayed in Styleguidist UI?
+
+You might want to change your components' names to be displayed differently, for example, for stylistic purposes or to give them a more descriptive names in your styleguide.
+
+This can be done by adding [@visibleName](Documenting.md#defining-custom-component-names) tag to your component documentation.
+
+In case you want to change components' names in bulk, for example, based on their current name, you can use [updateDocs](Configuration.md#updatedocs) config option:
+
+```javascript
+module.exports = {
+  updateDocs(docs) {
+    if (docs && docs.displayName) {
+      docs.visibleName = docs.displayName.toLowerCase()
+    }
+    return docs
+  }
+}
+```
+
 ## What’s the difference between Styleguidist and Storybook?
 
 Both tools are good and mature, they have many similarities but also some distinctions that may make you choose one or the other. For me the biggest distinction is how you describe component variations.

+## Defining custom component names
+
+Use @visibleName JSDoc tag to define component names that are used in the Styleguidist UI:
+
+```javascript
+/**
+ * The only true button.
+ *
+ * @visibleName The Best Button Ever 🐙
+ */
+class Button extends React.Component {
+```
+
+Now the component will be displayed with a custom 'The Bust Button Ever🐙' name and this will not change the name of the component that is used in the JSX.
+
 ## Using JSDoc tags
 
 You can use the following [JSDoc](http://usejsdoc.org/) tags when documenting components, props and methods:
