Creacion de script basico

Quiero un script de tampermonkey que muestre partes del codigo de una pagina web ya sea al inicio o final(no importa que se vea ordenado). El contenido del codigo cambia al agregarse nuevos elementos a la pagina. Que con pulsar ctrl F se pueda buscar como texto en la pagina web, son 3 elementos como el de a continuacion:
<div class="banking-category" id="category-0">(esto aparece al inspeccionar elemento, luego viene su contenido)
