+### Do not use this code.
+
+This is not a complete implementation of WireGuard. If you're interested in using WireGuard, use
+the implementation for Linux [found here](https://git.zx2c4.com/WireGuard/) and described on the
+[main wireguard website](https://www.wireguard.com/). There is no group of users that should be
+using the code in this repository here under any circumstances at the moment, not even beta testers
+or dare devils. It simply isn't complete. However, if you're interested in assisting with the
+Android development of WireGuard and contributing to this repository, by all means dig in and help
+out. But users: stay far away, at least for now.
