Missing info in documentation

I try to setup vosk as server via docker and want to test it with my microphone.
The documentation at https://alphacephei.com/vosk/server in the section "Testing with microphone" tells me to run ./test_microphone.py but it is not clear where in the repo this python script is located.

Please enhance or update the docu.

EDIT: Ok looks like this https://github.com/alphacep/vosk-server/blob/master/websocket/test_microphone.py is the mentioned file. Would be nice to clarify the docu :)
