+There is a hook available to quickly access Modalize. It returns an object with
+three keys:
+
+- `ref`: a ref object to pass to the `Modalize` component
+- `open`: a function that opens the `Modalize` component. If you are using
+  `snapPoint` prop, you can supply a `dest` argument to the `open`
+  function, to open it to the top directly `open('top')`. You don't have
+  to provide anything if you want the default behavior.
+- `close`: a function that closes the `Modalize` component. You don't need to call
+  it to dismiss the modal, since you can swipe down to dismiss.
+  If you are using `alwaysOpen` prop, you can supply a `dest` argument
+  to the `close` function to reset it to the initial position
+  `close('alwaysOpen')`, and avoiding to close it completely.
