+Endpoints grouping
+------------------
+
+Q: Areas feature doesn't fit my needs. So how can I group similar endpoints of one or more controllers in a separate section in the documentation?

+
+    /**
+     * Class BookmarkController
+     *
+     * @SWG\Tag(name="Bookmarks")
+     */
+    class BookmarkController extends AbstractFOSRestController implements ContextPresetInterface
+    {
+        //...
