help update wowza to 4.8.5 and setting webrtc on wowza

Hi, - upgrade the wowza actually on cent os to last version 4.8.5 - then I need to setup a webrtc one to many. I already use a wowza server for flash rtmp but as you know the flash will end soon. I need help in configuring my wowza server, set the html 5 media transmitter and the html 5 media receiver. I will need you to explain me what you do for me to learn The actual wowza server in on linux cent os this is a small per hour job but i maybe need more help in understanding how to configure wowza later.
