Looking for feedback on a security-related project idea
Idea: A free and open-source web repository of Sigma detections where users can find, contribute, and suggest edits to detections. All user contributions will go through a StackExchange-style moderation queue. Built-in conversion from Sigma to the query language of your choice.

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.
