Each markdown file needs to start with some front matter. For example, the front matter of this page looks like:
title: Front Matter
last_updated: 2021-04-01
toc: false
sidebar: unidata_sidebar
permalink: front_matter.html
breadcrumbs: false
More information about front matter can be found here.
Specific to the Unidata theme
The Unidata extensions to the base theme added a breadcrumb feature.
By default, the breadcumbs are enabled.
To disable the breadcrumbs on a given page, set breadcrumbs: false in the front matter.
Note that this page was generated using breadcrumbs: false in the front matter of the source markdown file.
