 ## Best Practices
 
 ### Do's
+
 - **Make steps idempotent** - Safe to retry
 - **Design compensations carefully** - They must work
 - **Use correlation IDs** - For tracing across services

 ### Don'ts
+
 - **Don't assume instant completion** - Sagas take time
 - **Don't skip compensation testing** - Most critical part
 - **Don't couple services** - Use async messaging
