 ## Associating the anchor and tooltip (1.3.1)
 
-So screen readers announce the tooltip content when the anchor is focused, add an `aria-describedby` attribute to the anchor referencing the tooltip's `id`.
+This one is handled for you. While the tooltip is open, ReactTooltip adds its `id` to the active anchor's `aria-describedby` attribute (merging with any values already there), and removes it again when the tooltip closes. This is what lets screen readers announce the tooltip content when the anchor is focused.
 
 ```jsx
-<button
-  data-tooltip-id="my-tooltip"
-  aria-describedby="my-tooltip"
->
-  Help
-</button>
+<button data-tooltip-id="my-tooltip">Help</button>
 <Tooltip id="my-tooltip" content="Helpful description" />
 ```
 
+:::caution
+
+Don't add the tooltip's `id` to the anchor's `aria-describedby` yourself. ReactTooltip manages it automatically, and a static attribute would point at the tooltip element even before it has been rendered (the tooltip is only added to the DOM once it opens).

-ReactTooltip renders the tooltip element with `role="tooltip"`, so pairing it with `aria-describedby` gives assistive technologies the expected semantics.

 ## Putting it all together
 
-This example combines all of the above: a keyboard-focusable anchor, associated with the tooltip via `aria-describedby`, whose content is reachable (`clickable`) and can be dismissed with <kbd>Esc</kbd> (`globalCloseEvents`).
