Create a simple 2-column pdf cheatsheet like so:
Make sure you have TeX distribution installed, such as texlive.
Write your cheatsheet out in pandoc markdown.
Limit code block width, since output will be 2-column.
Use column-breaks (
\newpage) as needed.
Process the doc:
pandoc -s \ -V geometry:"margin=0.5in,twocolumn,landscape" \ -o cheatsheet.tex \ cheatsheet.md pdflatex cheatsheet.tex
