There are lots of documentations that are about how-to's, not necessarily pertaining to technology (submitting forms, requesting accesses, etc).

The problem is that there are A LOT, and it's very hard to go search for one that I need.

Is there a way to manage this properly? What's the best way?

I was thinking about writing a bunch of markdown docs and serve it locally... (None of the info can be uploaded online, so it needs to be stored in a git repo and only accessible offline).
