When to Use It
✅ Building API or SDK that needs docs
✅ Want professional docs without hiring tech writer
✅ Docs constantly out of sync with code
✅ Open-source project needs better documentation
When NOT to Use It
❌ Internal tools (docs overkill)
❌ Happy with existing docs solution
❌ Project too small for formal documentation
Bottom line: Makes documentation actually happen. Lowers barrier from "someday" to "done today." Best for products that need public-facing docs.
