This is a template for a colourful cheatsheet.
It supports some visualization features and code listings using tcolorbox / minted. Just input the language you want (and that is supported by minted) in the codebox environment
Different colour themes will probably be added at some point.
(maybe also a more print friendly black and white alternative)
A blog post on cheatsheets and some of my thoughts on them and this template can be found here.
