+## Warning
+
+This repository [mriccobene/cppcoro](https://github.com/andreasbuhr/cppcoro) is a fork of the original [cppcoro library](https://github.com/lewissbaker/cppcoro) library.
+
+The differences to the original cppcoro are:
+* Replace <experimental/coroutine> with <coroutine>
+* Replace std::experimental:: with std::
+* Add Visual Studio 2019 project (v142, /std:c++latest)

 # CppCoro - A coroutine library for C++
 
 The 'cppcoro' library provides a large set of general-purpose primitives for making use of the coroutines TS proposal described in [N4680](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/n4680.pdf).
