 # Asynco
 
-A C++ library for event-driven asynchronous multi-threaded programming.
+A C++ library for event-driven asynchronous multi-threaded programming that serves as a runtime for asynchronous operations. It acts as a wrapper around the Boost.Asio library, providing a cleaner way to write asynchronous, concurrent, and parallel code utilizing a set of threads and an event loops. It offers features for event-driven programming, timers, and coroutine support.
 
 ## Motivation
 
-The original concept was to create an interface capable of asynchronously calling any function. It has since evolved into a library that incorporates a thread pool, each with its own event loop, event-driven programming, and functions inherently designed for asynchronous operation (including periodic and delayed functions).
+The initial goal was to create an interface that makes it easy and clean to asynchronously invoke any function in C++ without resorting to complex calls. Initially, the library was built around a custom implementation of a scheduling loop for queuing functions. However, this part was later replaced with Boost.Asio, mainly for its timer functionality. As the library evolved, it expanded to include a thread pool, each with its own event loop, and adopted event-driven programming. This enhancement also introduced functions specifically designed for asynchronous operations, including periodic and delayed execution.
 
-The asynchronous filesystem is provided solely to guide users on how to wrap any time- or IO-intensive function for asynchronous execution.
+The asynchronous filesystem was included solely to demonstrate how users can wrap any time- or I/O-intensive functions for asynchronous execution.
 
 ## Features
 
 - Object oriented
 - Small and easy to integrate
-- Header only
 - Asynchronous programming
 - Multithread
-- Asynchronous timer functions: periodic, delayed (like setInterval and setTimeout from JS)
+- Asynchronous timer functions: Periodic, Delayed (like setInterval and setTimeout from JS)
 - Typed events (on, tick, off) (like EventEmitter from JS: on, emit, etc)
 - Event loops
 - Multiple parallel execution loops
-- Asynchronous file IO
 - Based on ASIO (Boost Asio)
+- On C++20 support Boost.Asio coroutines
 ## Installation

 ## Usage
 
-Time asynchronous functions
+In the following sections, we will explore timers, function execution via the runtime, asynchronous invocation, and waiting for results. We will cover essential use cases involving triggers, and coroutines.
+
+### Timers
+
+We have one timer classes, int two mode Periodic (which runs a callback function periodically), and Delayed (delayed runs a callback function only once).
 
 ```c++

+## Coroutine
 
-Asynchronous file IO
+If `define.hpp` is included, you can initialize coroutines with `boost::asio::awaitable<T>`.
 
 ```c++
-string data_;
 
-fs::read("test.txt", [&data_] (string data, exception* error) {
+awaitable<int> c2(int a) {
-    if (error) {
+    co_return a * 2;
-        cout << "Error " << error->what() << endl;
-    } else {
-        cout << "Data " << endl << data << endl;
-        data_ = data;
-        cout << "Data_" << data_ << endl;
-    }
-});
-
-fs::write("test1.txt", "Hello world", [] (exception* error) {
-    if (error) {
-        cout << "Error " << error->what() << endl;
-    } else {
-        cout << "Write successfuly" << endl;
-    }
-});
-
-auto future_data = fs::read("test.txt");
-
-try {
-    string data = await_(future_data);
-} catch (exception& err) {
-    cout << err.what() << endl;
-}
-
-auto future_status = fs::write("test.txt", "Hello world");
-
-try {
-    await_(future_status);
-} catch (exception& err) {
-    cout << err.what() << endl;
 }
 
 ```
+To run the coroutine at runtime, simply call:
+```c++
+
+async_(c2(4));
+
+```
+Or using a lambda expression:
+
+```c++
+
+async_([]() -> awaitable<void> {
+    std::cout << "Hello" << std::endl;
+    co_await c2(4);
+    co_return;
+}());
+
+```
+To retrieve results from coroutines, you can do so as you would from classical functions by calling `await_`:
+```c++
+
+int r = await_(
+    async_(
+        c2(10)
+));
+
+```
+
+If you need the result immediately, you can use a shorter notation
+
+```c++
+
+auto a =  await_ ( c2(3));
+cout << a << endl;
+
+await_ ([]() -> awaitable<void> {
+    cout << "Hello" << endl;
+    co_return;
+}());
+
+```
+
+If you need a result, you can also retrieve it with `await_`.
+Here too you can use your own runtime instance, only the methods are `.async()` and `.await()`
