+##### Cookie domain
+Ouibounce sets a cookie by default to prevent the modal from appearing
+more than once per user. You can add a cookie domain using
+`cookieDomain` to specify the domain under which the cookie should work.
+By default, no extra domain information will be added. If you need a
+cookie to work also in your subdomain (like blog.example.com and
+example.com), then set a cookieDomain such as .example.com (notice the
+dot in front).
+
+_Example:_    
+```js
+ouibounce(document.getElementById('ouibounce-modal'), { cookieDomain:
+'.example.com' });
+```
+
 ##### Sitewide cookie
 You can drop sitewide cookies by using this option.
