I got 1.5 paragraphs into this article and ran into the term "helm chart", which I'd never heard before. I searched it and lo and behold, it (Helm) is a package management system for Kubernetes [1].
I'm sure this is quite basic entry-level stuff for the Kubernetes platform, but I haven't used it before. I find myself reading random articles on the topic so I can try to find an interesting use case for it but every time I seem to run into some new terminology like this and feel even more lost than I was before :)
