Here is how you get it going.

1. download version 3 zip file located on this page somewhere

2. run scripts (install dependencies first, then make, and if you want, connect to my public server)

3. Do NOT press the loopback button, it will cause hearing damage

4. press Talk to enable microphone. Do not forget to press it again to let other people talk. (thats push to talk operation, yes)

5. The latency is high, and that is ok, this thing is designed around big latencies, it is fine.
