How to create a page with a list of subpages including text from that subpages.

Hello, I'm new to Perch so if my question was already answered I'm sorry for asking again, but I didn't find it.

So I want to create a job page with a list of all available open positions. I already created a template for the "job detail" page where all the requirements are listed.

But I didn't understand how to build a page with a list of all that "job detail" pages where I can show the "job title" and a small description already included in the "job detail" page / template and a link to the detail page.

I hope someone can understand my question.

Greetings, Sven
