The worst thing is that I have often gone through a lot of effort around making it easy to set up and deploy (docker and whatnot) but even that I have forgotten about. (I came across a docker file in an old project and couldn't get it to work properly until I noticed that there was a docker compose file lying around that I had missed)
How do you keep track of documentation? I guess for a project a README in the git's root is a good start, but what about more complex systems stuff that does not live in a git project? For example, I had to manually edit a bunch of config files on my Proxmox setup to get docker and some other things to work properly. Where would I document such manual steps? I am thinking a text file somewhere in cloud storage but then of course I'd need to remember that...
