+# WebRTC
+
+This directory contains the WebRTC test suite.
+
+## Acknowledgements
+
+Some data channel tests are based on the [data channel conformance test
+suite][nplab-webrtc-dc-playground] of the Network Programming Lab of the Münster
+University of Applied Sciences. We would like to thank Peter Titz, Felix Weinrank and Timo
+Völker for agreeing to contribute their test cases to this repository.
