The best way I can describe core infrastructure is that it’s notes on any systems, process or setups that I consider essential to my conscious existence.

There should be a list of stuff in here at the bottom, but for clarity, “core infrastructure” specifically is not just:

• “things I like”, because some things I consider essential, but I use them begrudgingly, and document them here.
• “things I use regularly”, because I hopefully never have to use my backups, but this is where I tend to keep my notes on backup processes.
• “useful tools”, because there are plenty of useful tools out there which either I don’t use, or help me do things I consider non-essential which I wouldn’t include here.
• “essential tech for everyone”, because it includes non-tech and is my personal selection of things that work for me.

tldr; “things I consider essential for me”
