 - Automatically restarts CasWAF if it crashes
-- Prevents restart loops with smart restart limits
+- Prevents restart loops with smart restart limits (max 5 restarts in 5 minutes)
 - Works cross-platform (Windows, Linux, macOS)
 - Uses pure Go with no external dependencies
 
-For more details, see [supervisor/README.md](supervisor/README.md).
