At this point the project is primerly intended to be used by checking it out and modifying main.go, however you can also use it by downloading the binaries from releases.
Go command-line application to make chrome generated webrtc diagnostic packet and event recording human readable.
For more information see here.
To regenerate proto files, call docker-compose up in this directory.
go run main.go <log file>
