Git and all related things.
The products & services in the title are key to so many organisations. I will focus on learning GitHub's services and features as much as possible, but also compare to alternates such as GitLab and I have an account there too. I will try to compare/contrast where necessary for my own benefit and share here.
I've decided to pay for a "Pro" GitHub Account - just because, I've also decided to sponsor Jeff Geerling as I read a lot of his material and watch his awesome videos on YouTube. Top bloke.
