[jitsi-dev] videobridge - how to start

I wanted to create website with video chat.
I have to create my own user interface and this is why i need to integrate my code with videobridge.
What i have now is running videobridge and openfire on my ubuntu machine(https://jitsi.org/Projects/JitsiVideobridge)
Please give me some tips what to do next. I'd like to send video stream from my laptop camera.
I have experience with JavaEE, javascript, jquery.
