Noob question about post-processing

Hi.

I have just started learning Unity and I am trying to get a feel for post-processing. I have installed the URP package and created my global volume. However I cant figure out how to activate it. The official URP docs say that i should tick the post-processing box on the main camera object. The problem is that no shuch option exist, the properties of the camera component look completly different from the what the docs show.

Can someone pls explain whats going on or point me to some docs that make sens.
I am using version 2020.3.2f1, if thats relevant.

thanks.

Installing the Universal Render Pipeline into an existing Project

ALSO: put your project under source control or FULLY back it up before you try this.

Ok thanks, i now get what the problem was. And for my fellow idiots reading this in the future, make sure to chose Universal rp (or hdrp) when starting a new project.
