Jmeter Websocket Sampler Support to Upload file

[paul baboo]

Hi

       I have an application which uses the technology "*Web socket*" to
upload files and my task is to do the load testing on the upload.I
installed a jar file(from
https://github.com/maciejzaleski/JMeter-WebSocketSampler/releases)  which
supports Web socket sampler in Apache Jmeter,but i do not know how to
upload a file by that. Can you please guide me how to pass the "file" in
the Web socket sampler

Thanks

Regards
