+## OrbitControls from `cientos`
+
+Here is where the fancy part begins. The `cientos` package provides a component called `<OrbitControls />` that is a wrapper of the `OrbitControls` from the `three-stdlib` module.
+
+The nicest part? You don't need to extend the catalogue or pass any arguments. It just works.
