How do you actually threat hunt?
Agreed in general. But with stuff like SIGMA, I'd lean towards stuff should going into git. Better version control, your docs can be markdown and live right next to your threat library, you can strap on CI/CD (so you can deploy/run stuff as part of a pipeline). Confluence is a great start, but it doesn't scale well.
