+If you are building for latest browsers and don't transpile the "class" keyword use the "no-classes-transpile" dist:
+```js
+import React from 'react';
+
+if (process.env.NODE_ENV !== 'production') {
+  const whyDidYouRender = require('@welldone-software/why-did-you-render/dist/no-classes-transpile/umd/whyDidYouRender.min.js');
+  whyDidYouRender(React);
+}
+```
+Not doing so will [result in a bug](https://github.com/welldone-software/why-did-you-render/issues/5)
+where a transpiled class tries to extend a native class:
+
+`class constructors must be invoked with |new|`.
+
+
 Then mark all the components you want to be notified about their re-renders with `whyDidYouRender` like so:
 
 ```js
