If you just want a different title and description for each page, you can make an additional page file under "files". In the Cayman package it's called "another-page.md". In the preamble to that page, you'd put:

---

layout: default

title: Title of your new page

description: Description of your new page

---

That should let you have different titles and descriptions on different pages, though the buttons will be the same on each as defined in the default layout.
