 # libdatachannel - C/C++ WebRTC DataChannels
 
-libdatachannel is a standalone implementation of WebRTC DataChannels in C++17 with C bindings. It enables direct connectivity between native applications and web browsers without the pain of importing the entire WebRTC stack. Its API is modelled as a simplified version of the JavaScript WebRTC API, in order to ease the design of cross-environment applications.
+libdatachannel is a standalone implementation of WebRTC DataChannels in C++17 with C bindings for POSIX platforms and Microsoft Windows. It enables direct connectivity between native applications and web browsers without the pain of importing the entire WebRTC stack. Its API is modelled as a simplified version of the JavaScript WebRTC API, in order to ease the design of cross-environment applications.
 
 This projet is originally inspired by [librtcdcpp](https://github.com/chadnickbok/librtcdcpp), however it is a complete rewrite from scratch, because the messy architecture of librtcdcpp made solving its implementation issues difficult.
