+ **Build using the VCPKG package manager. (when PR with new port will be merged)**
+* Install VCPKG.
+```
+git clone https://github.com/Microsoft/vcpkg.git
+cd vcpkg
+./bootstrap-vcpkg.sh
+./vcpkg integrate install

+* Install Rstein.AsyncCpp library.
+```
+vcpkg install rsasynccpp rsasynccpp:x64-Windows
+```
+_Remark: If you need  legacy await support (the /await compiler switch is used, coroutines are in the std::experimental namespace) install Rstein.AsyncCpp library using the command._
+```
+vcpkg install rsasynccpp[lib-cl-win-legacy-await] rsasynccpp[lib-cl-win-legacy-await]:x64-Windows
+```
+* Use the library.
+``` C++
+
+#include <iostream>
+#include <asynccpp/Tasks/TaskFactory.h> //Include required headers
+
+int main()
+{
+    //Create (hot) task using the TaskFactory.
+    auto task = RStein::AsyncCpp::Tasks::TaskFactory::Run([]{std::cout << "Hello from Rstein.AsyncCpp library.";});
+    std::cin.get();
