Hi, I'm really sorry, but I made some mistakes last time: I stupidly didn't copy the YAML ^^" (I think it made a difference because you had runtime: shiny) and one of the links didn't actually work, I just thought it did because (#top) links to the top of the document.
Does this maybe work for you?
## Introduction
## The Template
This should make a [link to the top of the page](#top).
This should make a [link to the introduction](#section-introduction).
This should make a [link to the template](#section-the-template).
