+== Customizing
+
+You can customize the pagination style as follows:
+
+ * It uses by default classes that Padrino Admin's CSS uses - so the default style will fit your admin pages
+ * The pages are enclosed by a div with "pagination" class
+ * Prev/next links has "prev_next" class
+ * First/last links has "first_last" class
+ * The numbers are enclosed by a div with "pages" clas
+ * Page links are, well, links inside that "pages" div
+ * And the current page is a span with "current" class
+
+Remember: not all templates have all those elements.
