 * Low invasion. All you need to do is add 2-3 annotations and the corresponding compensate methods.
 * Easy to deploy. All components can boot via docker.
 * Support both forward(retry) and backward(compensate) recovery.
-* Easy to extend other coordination protocol which is based on the Pack.
+* Easy to extend other coordination protocol which is based on the Pack, now we have Saga and TCC support out of box.
 
 ## Architecture
 ServiceComb Pack is composed of  **alpha** and **omega**.
