 ## API
 
-### resetIdCounter(): void
-
-Allows reseting the internal id counter which is used to generate unique id's for tabs and tab panels.
-
-You should never need to use this in the browser. Only if you are running an isomorphic react app that is rendered on the server you should call `resetIdCounter()` before every page render so that the ids that get generated on the server match the ids generated in the browser.
-
-```js
-import { resetIdCounter } from 'react-tabs';
-
-resetIdCounter();
-ReactDOMServer.renderToString(...);
-```
-
 ## Components
