How can you stream on twitch games?

I just registered with twitch and would like to play live how it works?
I have a youtube channel with the same account

Powerful PC with very strong CPU (Ryzen 7 from 1700 better 2800X eg.) And an upload line of at least 6 Mbit are optimal conditions.

And of course a streaming program like xSplit, OBS etc

Logically… Where except on Xsplit there's free.

Jo and how do I get into the streaming?

First of all, you should tell us which CPU you have and what kind of upload line. Then you download OBS, set everything, stream key etc., bitrate, audio, resolution, etc., and then you can start streaming.

Well set right scenes etc. Etc.
Gives enough instructions on Youtube.

Obs, I have just opened the twitch channel fresh. Streaming key tells me nothing at all I want to play cod-cod live streaming. I do not know CPU

Is this vl

Intel Core (TM) i7-6700CPU3,40GHz?

Upload 50 mbits, donwload 6 mibts if it is not the other way around

Watch a youtube video about it. If you do not even know your Pc, it will be hard to explain the stream to you
