University of Reading Computer Science Report Template and Guide. This is a report template as well as has instructions on writing various types of reports: e.g. science and lab, software engining and algorithms.
This is an update on my old "Colourful Cheatsheet Template". It is based on the old one, so similar but not the same.
It still supports all the old visualization features and code listings using tcolorbox / minted. Just input the language you want (and that is supported by minted) in the codebox environment.
However, the style now is a bit less bright and mimicks the Metropolis beamer template in style (a bit).
This is the blogpost to go with it: https://latex-ninja.com/2021/10/01/a-new-version-of-the-colourful-cheatsheet-template/
