pandoc markdown snippets

I like writing using Markdown, and I like how LaTeX documents look. Pandoc allows me to write in Markdown and render it to PDF with LaTeX, but the defaults are sometimes not that great.

I usually start my documents with this:

---
title: Some Document
author: |
  kitsune\
  email@example.org
date: Thursday, 3 March 2022
papersize: a4
geometry: margin=2cm
documentclass: article
header-includes:
  - \usepackage{multicol}
  - \newcommand{\hideFromPandoc}[1]{#1}
  - \hideFromPandoc{ \let\Begin\begin \let\End\end }
---
