Floating Terms(What it is)???

So,being into proper web development for last one year,I come across a number of floating terms(headless CMS,static generator,bundler and so on) that make it more intimidating for newbies to grab the concepts. I learned most of the terms the hard way.
Won't it be helping anyone if we make a common GitHub repo where anyone can explain these terms in a layman way through pull requests and then whosoever is writing a technical post,can include those jargons as a link to the GitHub repo. If the reader need to know more,they can visit the site,else an experienced reader can go and finish reading the article.
Thoughts please(or clarity if we are already having some service like this).
