+
+### Valid `casing` options
+
+```js
+{
+  // Don't convert names
+  casing: undefined
+}
+
+{
+  // Show names in kebab-case
+  casing 'kebab'
+}
+
+{
+  // Show prop names in camelCase and
+  // Show component names in PascalCase
+  casing: 'camel' // or 'pascal'
+}
+
+{
+  // Show prop names in camelCase and
+  // Show component names in kebab-case
+  casing: {
+    props: 'camel',
+    component: 'kebab'
+  }
+}
+```
 
 In addition to addon options, we have a component option.
