This site is created using Hugo a static site generator, and with a slighty changed theme called Learn.
All the content is written in Markdown, and sometimes using Learn’s shortcodes for extra functionalities like with notices, attachments, diagrams, etc.
Content files live in the Content folder, have an md extension, and begin with a YAML/TOML piece of data called frontmatter:
+++
title = "Some title"
menuTitle = "Title"
date = 2019-06-18T14:00:00+02:00
weight = 20
