How do you keep IT documentation if a lot of customer service?

Question

Documentation

Who has some experience in automating IT documentation? If you are sis. admin work in a team and you have many clients.

I mean different settings, passwords, schemes that are in one place and that are needed both by myself and other team members. At the moment I use Evernote, Google disk, but maybe there is something more suitable, with the distribution of rights, versioning, ease of access, and so on.
Thank you.

Answer 1

than jira and confluence do not suit?

Answer 2

Any task tracker (fat, yutrek, and others) + wiki (confluence, the same yutrek, xwiki).
You can, in principle, shove everything into a notion.
For passwords / configs and other things, you can still use Vault (or any other password / secret manager) or stupidly add it to git (there will be versioning out of the box)
