-By linking with libco, you can easily transform synchronous back-end service into co-routine service, which provide out-standing concurrency compare to multi-thread approach. You get both happy coding in synchronous way and performance improve.
+By linking with libco, you can easily transform synchronous back-end service into co-routine service, which provide out-standing concurrency compare to multi-thread approach. With the system hook, You can easily coding in synchronous way but asynchronous executed.
 
 You can also use co_create/co_resume/co_yield function for asynchronous back-end service, which give you more control of when should I switch between co-routine.
