I can't figure out how to use 'assign section layouts' to compile a synopsis

When I try to follow the instructions I have found online they assume prior knowledge of section layouts and gallop ahead of me so fast I can’t follow. This is something I’ve spent ages trying to puzzle out and I am clearly just too stupid to understand it. If someone could point me to an idiotproof set of instructions for how to get a synopsis out of scrivener I would be enormously grateful. I know it must be possible!
