@@ -21,11 +22,19 @@ The extension ships with support for items of type ``pages``,
 but this is more a demonstration an used for testing.
 Projects are way too different and should provide their own items, see "Custom Items".
 
+The extension also provides a JavaScript which will parse data-Attributes of DOM and
+attach listener to add elements to the watchlist.
+
 Custom Items
 ============
 
 A developer needs to implement an ``ItemHandler`` and an class representing the ``Item``.
 
+The used identifier has to be unique throughout the system. The first part is the
+item type which is returned by the ItemHandler to be handled, followed by a minus and
+the rest of the identifier, leading to: ``<type>-rest-of-identifier``.
+Commas should not be used within the identifier.
+
 ``ItemHandler``
 ---------------
 
@@ -51,3 +60,45 @@ The Handler needs to be registered via Symfony Tags, e.g. via ``Services.yaml``:
 --------
 
 The class needs to implement the ``WerkraumMedia\Watchlist\Domain\Model\Item``.
+
+JavaScript
+==========
+
+The JavaScript respects two ``data-`` attributes:
+
+``data-watchlist-counter``
+   Defines that this element will hold the current number of items on watch list.
+   The JavaScript will update the content of the element.
+
+   .. code:: html
+
+      <span data-watchlist-counter class="watchlist-badge-counter"></span>
+
+``data-watchlist-item``
+   Defines that this element represents an actual item.
+   The attribute needs the identifier of the item as value, e.g.: ``data-watchlist-item="page-1"``
+
+   An EventListener will be added listening for click events on that element.
+   Each click will toggle the state of the item on the watch list.
+
+   The JavaScript will add a CSS class to the element, depending on the state of the item.
+   ``watchlist-inactive`` will be added in case the item is not on the watchlist.
+   ``watchlist-active`` will be added in case the item is on the watchlist.
+
+A custom Event will be triggered whenever an item is added or removed from the watchlist.
+The event is triggered on the ``document``.
+The event provides the identifier of the item.
+An example listener can look like:
+
+.. code:: js
+
+   document.addEventListener('WatchlistUpdate', function(event) {
+       console.log(event.detail.watchlistItem);
+   });
+
+Example
+-------
+
+A concrete example can be found within ``Tests/Fixtures/FrontendRendering.typoscript``.
+This example includes the provided JavaScript file as well as some custom CSS and Markup.
+The content element is not necessary.
