Any (sub)forum on Yocto Project?

I'm new to using Yocto, and wonder if there is a place where I could ask questions specific to Yocto project. Currently, my focus is in configuration, and board bring-up using specific BSP from Yocto (initially using prebuilts).

Or is this THE place?

Just find a sub-forum where it fits. I'd suggest software. all the sub forums have a description stating what is allowed for that particular section. Of course there's always General.
