-A high-performance framework for building asynchronous and multi-threaded programs. 
+A high-performance [liburing](https://github.com/axboe/liburing) backed event loop for building asynchronous and multi-threaded programs. 
 
 The original goal of this library was to learn the [new coroutines TS](https://en.cppreference.com/w/cpp/coroutine) for C++. I found the most difficult part of the coroutine TS is when you want to develop an asynchronous architecture or "executer/runtime" that can handle re-entrant code across possibly different threads. Thus, **ZAB** was born.
