So, I just published "Building software together with Git" on my #blog: https://eliotberriot.com/blog/2019/03/05/building-sotfware-together-with-git/ 🎉
It's a rather high-level, non-technical overview explaining what is software collaboration and how tools like #Git and #GitHub actually help with that.
It assumes little prior knowlegde from the reader, and attempts to explain the technical concepts in accessible ways.
Many thanks to @GinnyMcQueen for the initial idea, @y6nH for proofreading and everyone for the feedback!
