-Usage:
+**Usage:**
 
-$('img[usemap]').rwdImageMaps();
+* Add a link to jQuery in your page, preferably at the bottom just before the closing `</body>`
+* After jQuery, either in a `<script>` block or a separate file, call:
 
-* * *
+`$('img[usemap]').rwdImageMaps();`

+You may also want to wrap it inside a `$(document).ready()` function, like so:

+$(document).ready(function(e) {
