Stream on Twitch, OSB Streamlabs?

I would like to start streaming at Twitch and I really don't know much about it! Can someone help me with the settings for OSB Streamlabs?

LG and thanks in advance

On YouTube you will find many helpful videos that explain step by step what you should set up and what exactly what is.

As far as the stream settings are concerned, it is good to know what hardware you have. And what games you want to play. It often fails because it is too bad.

As for the hardware, I should be well equipped. Sufficiently large SSD's, 3800x and another gtx 1070. Could I write for detailed questions?
