Pull request templates

One of my favorite little Marie-Kondo/Clean Cody tidbits I have really latched onto since joining Robin is their use of pull request templates in our Github repo. All it is, is a little file name pull_request_template.md that goes inside a .github directory in your project. It really didn't take that long to get use to - and my PR descriptions went from maybe couple sentences (or just one...) of vague description - to generally well formatted lists, images, gifs and context on how to interpret and test the PR. Seems like an obvious addition to a project in hindisght, yet I still have not added one to this blog's repo... 🤦
