My home lab has a mild amount of complexity and I'd like practice some good habits about documenting it. Stuff like, what each system does, the OS, any notable software installed and, most importantly, any documentation around configuration or troubleshooting.
i.e. I have an internal SMTP relay that uses a letsencrypt SSL cert that I need to use the DNS challenge to renew. I've got the steps around that sitting in a Google Doc. I've got a couple more google docs like that.
I don't want to get super complicated but I'd like something a bit more structured than a folder full of google docs. I'd also like to pull it in-house.
Thanks
Edit: I appreciate all the feedback I've gotten on this post so far. There have been a lot of tools suggested and some great discussion about methods. This will probably be my weekend now.
I know that I would keep forgetting to update the docs, so my documentation are the ansible playbooks and docker-compose.yaml files that I use to set it all up.
That leaves anything that has to be done in some Ui undocumented, so I try to keep that to a minimum, which isn't always easy (I'm looking at you authentik!).
Ideally I'd like to move in that direction. I have some Ansible roles that I use for initial configuration but I haven't kept current. I'd like to get better about that as part of this project.
