Ask HN: Any Tips on Handling Distributed Knowledge Bases?

Hello. I'm currently working in consultancy, with multiple teams distributed across various domains and timezones.

Often I find that there are specific processes that need to be documented (or for which I need to find documentation for). I.e. script locations, set up instructions, caveats for specific executions etc.

It happens often that I write something just to find out later that the same information was already present somewhere else, written by someone two weeks ago, buried in confluence subfolders.

I'm looking for any advice to optimize cross-team information distribution, searchability and availability. Specifically for information that doesn't easily lend itself to structured locations like readmes and code documentation.

Are there best practices or tools that you could recommend?
