 ## Controlled Popover
 
-To make it easier to implement the popover in your app, you can set the
-`popoverHelperId` prop to the same ID as the `popovertarget` of a trigger.
-This uses the browser Popover API and will control the popover by closing it
-when the trigger or backdrop is pressed.
+Popover API can be used to control visibility of Popover component. You need to
+set `id` on the trigger element and matching `popoverTargetId` attribute on the
+Popover component. This leverages the browser's Popover API to control the
+popover, automatically closing it when the trigger or the backdrop is pressed.
