+#### Usage with TypeScript
+
+In TypeScript, you can specify the custom component type used in the `slots.root` as a generic parameter of the unstyled component. This way, you can safely provide the custom root's props directly on the component:
+
+```tsx
+<Switch<typeof CustomComponent> slots={{ root: CustomComponent }} customProp />
+```
+
+The same applies for props specific to custom primitive elements:
+
+```tsx
+<Switch<'input'> slots={{ root: 'input' }} autoFocus={true} />
+```
