+#### Usage with TypeScript
+
+In TypeScript, you can specify the custom component type used in the `slots.root` as a generic to the unstyled component. This way, you can safely provide the custom compoenent's props directly on the compnent:
+
+```tsx
+<FormControl<typeof CustomComponent> slots={{ root: CustomComponent }} customProp />
+```
+
+The same applies for props specific to custom primitive elements:
+
+```tsx
+<FormControl<'button'> slots={{ root: 'button' }} onClick={() => {}} />
+```
+
 ## Hook
