 quic-go is an implementation of the [QUIC](https://en.wikipedia.org/wiki/QUIC) protocol in Go. While we're not far from being feature complete, there's still a lot of work to do regarding performance and security. At the moment, we do not recommend use in production systems. We appreciate any feedback :)
